As a project within this program, the coal-bearing Ghazij Formation (Eocene) was investigated in the northeastern part of Balochistan cast and south of the provincial capital of Quetta. Strata exposed in this area range in age from Permian to Holocene and crop out as a belt of folded and thrusted rocks that form a southeast-facing orocline. In this region of Pakistan, the Ghazij can usually be divided into three parts. The lower part is the thickest (probably more than 1,000 m) and consists of gray-weathering calcareous mudrock (shale, mudstone, and impure claystone) and a few tabular bodies of fine-to medium-grained calcareous sandstone. The middle part (27-300 m) consists of gray-weathering calcareous mudrock and tabular to lenticular bodies of fine-to medium-grained calcareous sandstone; beds of carbonaceous shale and coal are common. The upper part (as thick as 533 m) contains reddish-weathering calcareous mudrock that contains scattered lenticular bodies of fine- to medium-grained calcareous sandstone. Fossil plant debris is common in mudrock of the lower and middle parts of the Ghazij, and bivalves and gastropods are common in the middle part; the upper part of the Ghazij is usually unfossiliferous. This three-fold division of the Ghazij is less distinct in the Johan area. Here, the upper part of the formation is clearly identifiable, but rocks below it are poorly exposed and assigning a stratigraphic level that separates the middle and lower parts of the formation is problematic. Below the upper part of the formation is a thick sequence of greenish-gray calcareous mudrock that contains locally abundant plant debris and isolated bodies of brown-weathering sandstone. Rare carbonaceous shale and even rarer coal are present in the upper part of this sequence, and this interval of the formation might correspond to the middle part of the Ghazji exposed in areas to the north. We propose that, in the Johan area, those rocks below the upper part of the formation be referred to as the main body of the Ghazij (for example, main-body Ghazij). Underlying the Ghazij are the carbonate rocks of the Paleocene Dungan Formation (or its equivalent), and overlying the Ghazij are the mostly carbonate rocks of the Eocene Kirthar Formation (or its equivalent). Both contacts can be conformable or unconformable. All of the pre-Neogene rocks in Balochistan are greatly deformed by the collision of India and Asia. The Ghazij is especially susceptible to regional compressional tectonics because it contains a large amount of shale and is sandwiched between two thick carbonate units. As a result, bedding-plane faults and isoclinal folds are common. As part of our study of the Ghazij Formation, five stratigraphic sections were measured: one near Pir Ismail Ziarat, one in the Sor Range, two in the vicinity of Mach, and one near Johan. Each area's section is published separately.

Strata exposed in this area range in age from Permian to Holocene and crop out as a belt of folded and thrusted rocks that form a southeast-facing orocline. In this region of Pakistan, the Ghazij can usually be divided into three parts. The lower part is the thickest (probably more than 1,000 m) and consists of gray-weathering calcareous mudrock (shale, mudstone, and impure claystone) and a few tabular bodies of fine-to medium-grained calcareous sandstone. The middle part (27-300 m) consists of gray-weathering calcareous mudrock and tabular to lenticular bodies of fine- to medium-grained calcareous sandstone; beds of carbonaceous shale and coal are common (in the Mach area, the middle part of the formation also contains numerous individual beds of muddy limestone). The upper part (as thick as 533 m) contains reddish-weathering calcareous mudrock that contains scattered lenticular bodies of fine-to medium-grained calcareous sandstone. Fossil plant debris is common in mudrock of the lower and middle parts of the Ghazij and bivalves and gastropods are common in the middle part of the formation; the upper part of the Ghazij is usually unfossiliferous. Underlying the Ghazij are the carbonate rocks of the Paleocene Dungan Formation (or its equivalent), and overlying the Ghazij are the mostly carbonate rocks of the Eocene Kirthar Formation (or its equivalent). Both contacts can be conformable or unconformable. All of the pre-Neogene rocks in Balochistan are greatly deformed by the collision of India and Asia. The Ghazij is especially susceptible to regional compressional tectonics because it contains large amounts of shale and is sandwiched between two thick carbonate units. As a result, bedding-plane faults and isoclinal folds are very common. As part of our study of the Ghazij Formation, five stratigraphic sections were measured: one near Pir Ismail Ziarat, one in the Sor Range, two in the vicinity of Mach, and one near Johan.

As a project within this program, the coal-bearing Ghazij Formation (Eocene) was investigated in the northeastern part of Balochistan cast and south of the provincial capital of Quetta. Strata exposed in this area range in age from Permian to Holocene and crop out as a belt of folded and thrusted rocks that form a southeast-facing orocline. In this region of Pakistan, the Ghazij can usually be divided into three parts. The lower part is the thickest (probably more than 1,000 m) and consists of gray-weathering calcareous mudrock (shale, mudstone, and impure claystone) and a few tabular bodies of fine-to medium-grained calcareous sandstone.

The upper part (as thick as 533 m) contains reddish-weathering calcareous mudrock that contains scattered lenticular bodies of fine- to medium-grained calcareous sandstone. Fossil plant debris is common in mudrock of the lower and middle parts of the Ghazij, and bivalves and gastropods are common in the middle part; the upper part of the Ghazij is usually unfossiliferous. This three-fold division of the Ghazij is less distinct in the Johan area. Here, the upper part of the formation is clearly identifiable, but rocks below it are poorly exposed and assigning a stratigraphic level that separates the middle and lower parts of the formation is problematic. Below the upper part of the formation is a thick sequence of greenish-gray calcareous mudrock that contains locally abundant plant debris and isolated bodies of brown-weathering sandstone. Rare carbonaceous shale and even rarer coal are present in the upper part of this sequence, and this interval of the formation might correspond to the middle part of the Ghazji exposed in areas to the north. We propose that, in the Johan area, those rocks below the upper part of the formation be referred to as the main body of the Ghazij (for example, main-body Ghazij). Underlying the Ghazij are the carbonate rocks of the Paleocene Dungan Formation (or its equivalent), and overlying the Ghazij are the mostly carbonate rocks of the Eocene Kirthar Formation (or its equivalent). Both contacts can be conformable or unconformable. All of the pre-Neogene rocks in Balochistan are greatly deformed by the collision of India and Asia.

Major revisions to the original correlation chart include formal naming of key marine units in Kentucky and replacement of informally named marine units incorrectly projected into Kentucky from adjacent states. Also included in the report is the proper correlation of some regionally recognized coal bed names that have been incorrectly projected into Kentucky, particularly from Ohio and West Virginia. Besides these additions and corrections, minor changes have been made to the correlation chart, all of which are discussed below in detail. The Pennsylvania rocks of the eastern Kentucky coal field underlie an area of about 27,000 square kilometers (see index map). Largely because of the size and stratigra[hic complexity of the area, Huddle and others (1963, p. 31) divided the coal field into six coal-reserve districts. District boundaries utilize state and county line as well as geologic features, drainage areas, and coal producing areas. Their division is followed herein because, in general, each of the districts has a characteristic stratigraphic nomenclature, particularly with regard to coal bed names. The six districts are the Princess, Licking River, Big Sandy, Hazard, Southwestern, and Upper Cumberland River district is divided into the Middlesboro and Harlan subdistricts. The correlation chart lists most of the stratigraphic units of Pennsylvanian age used in eastern Kentucky, and is concerned principally with coal bed names used in publications since about 1950, especially all of the names of coal beds for which resources and reserves have been calculated. Coal constitutes only a small percentage of the total Pennsylvanian-rock sequence, but is present in as many as 26 major coal zones that have been prospected and mined extensively in all parts of the coal field since the early 1900's. Coal names listed in this chart represent coal beds that have been mined commercially or used locally by residents of the area. Not every coal bed listed under a district in the chart is found in all parts of that district, nor has every coal bed been given a name. For the sake of saving space, coal beds commonly identified as a \"rider\" coal bed (commonly a minor coal or split above the main bed) or as a \"marker\" coal bed (a minor coal below the main bed) are not included in the chart because they do not contribute to the overall stratigraphic framework of the coal field. Most of the stratigraphic units listed in the correlation chart are defined and described in detail in almost 200 geologic reports of the Geologic Quadrangle (GQ) Map Series of the U.S. Geological Survey (USGS). These maps were published as a result of the cooperative geological mapping program of the USGS and the Kentucky Geological Survey; which was begun in 1960 and was completed in 1978. The GQ maps, at a scale of 1:24,000, describe the lithology and local stratigraphy and identify many coal beds by noth local and regional names. Other sources of stratigraphic information and coal bed names used in the construction of the chart include USGS bulletins dealing with the coal resources of single 7.5-minute quadrangles (Englund, 1955; Adkinson, 1957; Welch, 1958; Bergin, 1962). The coal resources of eastern Kentucky as a whole have been described by Huddle and others (1963) and detailed reports on the stratigraphy and coal resources of significant areas in eastern Kentucky have been made by Huddle and Englund (1966) and Englund (1968). An additional source of coal bed names is the SEAMS database, which is jointly sponsored by the University of Kentucky Center for Applied Energy Research, the Kentucky Geological Survey, and the Kentucky Department of Mines and Minerals. The SEAMS database identifies the stratigraphic position and location of all coal beds in the eastern and the western Kentucky coal fields as well as those of bordering areas in adjacent states. The databases includes references to all coal-bed names used in Kentucky, especially those shown on coal company mine maps. Local names of coal beds in the database file that are not generally used in publications are listed in table 1 together with their regional equivalents.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/mf2275","collaboration":"Prepared in cooperation with the Commonwealth of Kentucky, University of Kentucky, Kentucky Geological Survey, Donald C.

Lee in 1976 and 1978 (Normark and others, 1979) and later mapped in more detail during a swath-sonar survey (GLORIA) of the United States Hawaiian Exclusive Economic Zone in 1986 to 1991 (Lipman and others, 1988; Moore and others, 1989) as part of a cooperative venture of the U.S. Geological Survey and the British Institute of Oceanographic Sciences.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/mf2269","collaboration":"Prepared in cooperation with the U.S. Geological Survey--National Oceanic and Atmospheric Administration Joint Office for Mapping and Research","usgsCitation":"Chadwick, W.W., Moore, J.G., and Fox, C.G., 1994, Bathymetry of the west-central slope of the island of Hawaii: U.S. Geological Survey Miscellaneous Field Studies Map 2269, 1 Plate: 29.95 x 40.82 inches, https://doi.org/10.3133/mf2269.","productDescription":"1 Plate: 29.95 x 40.82 inches","costCenters":[],"links":[{"id":490327,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_5890.htm","linkFileType":{"id":5,"text":"html"}},{"id":183762,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/mf2269.jpg"},{"id":284468,"rank":2,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/2269/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"150000","projection":"Mercator projection","country":"United States","state":"Hawai'i","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -156.8,19.2 ], [ -156.8,20.0 ], [ -155.9,20.0 ], [ -155.9,19.2 ], [ -156.8,19.2 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd4ef6e4b0b290850f269b","contributors":{"authors":[{"text":"Chadwick, William W.","contributorId":77042,"corporation":false,"usgs":true,"family":"Chadwick","given":"William","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":261465,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moore, James G. 0000-0002-7543-2401 jmoore@usgs.gov","orcid":"https://orcid.org/0000-0002-7543-2401","contributorId":2892,"corporation":false,"usgs":true,"family":"Moore","given":"James","email":"jmoore@usgs.gov","middleInitial":"G.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":261464,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fox, Christopher G.","contributorId":86257,"corporation":false,"usgs":true,"family":"Fox","given":"Christopher","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":261466,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":58335,"text":"mf2233 - 1993 - Bathymetry of southern Mauna Loa Volcano, Hawaii","interactions":[],"lastModifiedDate":"2019-04-04T09:41:46","indexId":"mf2233","displayToPublicDate":"1994-01-01T07:00:00","publicationYear":"1993","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":325,"text":"Miscellaneous Field Studies Map","code":"MF","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"2233","title":"Bathymetry of southern Mauna Loa Volcano, Hawaii","docAbstract":"Manua Loa, the largest volcano on Earth, lies largely beneath the sea, and until recently only generalized bathymetry of this giant volcano was available. However, within the last two decades, the development of multibeam sonar and the improvement of satellite systems (Global Positioning System) have increased the availability of precise bathymetric mapping. This map combines topography of the subaerial southern part of the volcano with modern multibeam bathymetric data from the south submarine flank. The map includes the summit caldera of Mauna Loa Volcano and the entire length of the 100-km-long southwest rift zone that is marked by a much more pronounced ridge below sea level than above. The 60-km-long segment of the rift zone abruptly changes trend from southwest to south 30 km from the summit. It extends from this bend out to sea at the south cape of the island (Kalae) to 4 to 4.5 km depth where it impinges on the elongate west ridge of Apuupuu Seamount. The west submarine flank of the rift-zone ridge connects with the Kahuku fault on land and both are part of the ampitheater head of a major submarine landslide (Lipman and others, 1990; Moore and Clague, 1992). Two pre-Hawaiian volcanic seamounts in the map area, Apuupuu and Dana Seamounts, are apparently Cretaceous in age and are somewhat younger than the Cretaceous oceanic crust on which they are built.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/mf2233","isbn":"0607821965","usgsCitation":"Chadwick, W.W., Moore, J.G., Garcia, M.O., and Fox, C.G., 1993, Bathymetry of southern Mauna Loa Volcano, Hawaii: U.S. Geological Survey Miscellaneous Field Studies Map 2233, Map: 25.18 x 43.40 inches, https://doi.org/10.3133/mf2233.","productDescription":"Map: 25.18 x 43.40 inches","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":181014,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/mf2233.png"},{"id":284451,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/2233/plate-1.pdf"}],"scale":"50000","country":"United States","state":"Hawai'i","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -16.0,18.3 ], [ -16.0,19.3 ], [ -15.5,19.3 ], [ -15.5,18.3 ], [ -16.0,18.3 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd4ef6e4b0b290850f2693","contributors":{"authors":[{"text":"Chadwick, William W.","contributorId":77042,"corporation":false,"usgs":true,"family":"Chadwick","given":"William","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":258776,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moore, James G. 0000-0002-7543-2401 jmoore@usgs.gov","orcid":"https://orcid.org/0000-0002-7543-2401","contributorId":2892,"corporation":false,"usgs":true,"family":"Moore","given":"James","email":"jmoore@usgs.gov","middleInitial":"G.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":258774,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Garcia, Michael O.","contributorId":51636,"corporation":false,"usgs":true,"family":"Garcia","given":"Michael","email":"","middleInitial":"O.","affiliations":[],"preferred":false,"id":258775,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Fox, Christopher G.","contributorId":86257,"corporation":false,"usgs":true,"family":"Fox","given":"Christopher","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":258777,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":60630,"text":"mf2125E - 1993 - Assessment of the Joplin 1° x 2° quadrangle, Kansas and Missouri, for Mississippi Valley-type deposits and other minerals","interactions":[],"lastModifiedDate":"2021-10-22T19:03:45.048595","indexId":"mf2125E","displayToPublicDate":"1994-01-01T07:00:00","publicationYear":"1993","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":325,"text":"Miscellaneous Field Studies Map","code":"MF","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"2125","chapter":"E","title":"Assessment of the Joplin 1° x 2° quadrangle, Kansas and Missouri, for Mississippi Valley-type deposits and other minerals","docAbstract":"This map is a part of the folio of maps of the Joplin 1° X 2° quadrangle, Kansas and Missouri, which was prepared under the Conterminuous United States Mineral Assessment Program.
