All were found in Pleistocene glacial deposits or Holocene river gravel. The bedrock kimberlite source for the diamonds is unknown but has been presumed to be in northern Canada, the only area north of Wisconsin previously known to contain kimberlites. Recently, a kimberlite pipe, here named the Lake Ellen kimberlite, has been found in Iron County, Michigan. That find suggests the possibility that drift diamonds in Wisconsin have come from a more local source--kimberlites in northern Michigan and Wisconsin. \r\n\r\nThe Lake Ellen kimberlite is very poorly exposed, but a strong positive magnetic anomaly indicates that it is roughly circular in plan and about 200 m in diameter. Although the kimberlite is entirely surrounded by Precambrian rocks, it contains abundant inclusions of fossiliferous dolomite, probably from the Ordovician Black River Group that overlay the area when the kimberlite was intruded. The post-Ordovician age of the kimberlite leads us to suspect that other possible cryptovolcanic structures in Paleozoic rocks in the region were formed over kimberlite pipes that are not yet exposed by erosion. Such structures include Limestone Mountain and Sherman Hill, in Houghton and Baraga Counties, Michigan; Glover Bluff, in Marquette County, Wisconsin; and possibly an area along the Brule River south of Iron River, Michigan. \r\n\r\nNo diamonds are known in the Lake Ellen kimberlite, but it has not been adequately sampled. The cryptovolcanic structures could not be the source of the drift diamonds in Wisconsin because even if the structures are caused by kimberlites, those kimberlites have not yet been exposed by erosion. \r\n\r\nElsewhere in the world, kimberlite is seldom found as a single isolated body; clusters of bodies are more common, and the presence of one kimberlite implies that others may exist nearby. \r\n\r\nThe discovery of additional kimberlites may be very difficult because of the extensive cover of glacial drift and the typical small size of kimberlite bodies. If all are magnetic, they might be found by detailed aeromagnetic surveys. However, the magnetism of the Lake Ellen kimberlite appears to be caused by secondary magnetite formed during serpentinization of olivine, so an unserpentinized kimberlite may not be strongly magnetic. \r\n\r\nWe suggest that one or more diamond-bearing kimberlites may exist in northern Michigan or Wisconsin, but the discovery of such bodies is unlikely unless a very thorough search is undertaken.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/cir842","usgsCitation":"Cannon, W.F., and Mudrey, M., 1981, The potential for diamond-bearing kimberlite in northern Michigan and Wisconsin: U.S. Geological Survey Circular 842, iii, 15 p. :ill., map ;26 cm., https://doi.org/10.3133/cir842.","productDescription":"iii, 15 p. :ill., map ;26 cm.","numberOfPages":"18","costCenters":[],"links":[{"id":124490,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1981/0842/report-thumb.jpg"},{"id":31203,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1981/0842/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a71e4b07f02db641d68","contributors":{"authors":[{"text":"Cannon, William F. 0000-0002-2699-8118 wcannon@usgs.gov","orcid":"https://orcid.org/0000-0002-2699-8118","contributorId":1883,"corporation":false,"usgs":true,"family":"Cannon","given":"William","email":"wcannon@usgs.gov","middleInitial":"F.","affiliations":[{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":148186,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mudrey, M.G.","contributorId":69963,"corporation":false,"usgs":true,"family":"Mudrey","given":"M.G.","affiliations":[],"preferred":false,"id":148187,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

With the development of technology, exploration, development, and production are being extended to include areas off the coast of southwest Florida and deep-water areas near the Mississippi River Delta. Development in both areas requires careful analyses of local considerations. The hydrocarbon potential of the region, while not well established in the frontier portions, generally remains favorable. A total of 482 fields have been discovered to date in the federally regulated part of the Gulf of Mexico. Reserve estimates have been made for the 435 producing fields in the region. Through December 31, 1980, those fields have produced 5.0 billion barrels of oil and condensate, and 48.7 trillion cubic feet of gas. Remaining recoverable reserves are 3.1 billion barrels of oil and 40.2 trillion cubic feet of gas. Estimates of undiscovered recoverable resources for the Gulf of Mexico are 6.6 billion barrels of oil and 71.9 trillion cubic feet of gas.</p><p>Since enactment of the Outer Continental Shelf Lands Act in 1953, there have been 42 oil and gas lease sales in the Gulf of Mexico. An average of three lease sales per year are scheduled through 1986. Since 1953, the Bureau of Land Management (BLM) has leased 3,119 tracts in the Gulf of Mexico; 1,825 leases are currently active. The distribution of leased tracts exhibits a regionwide pattern as shown by Lease Sales A62, 62, A66, and 66. Proposed Lease Sales 67, 69, 72, and 74 will probably continue that pattern. Tracts off the coast of southwest Florida in the Charlotte Harbor, Howell Hook, and Pulley Ridge Areas will be offered in upcoming sales. Operations on tracts in deepwater areas slated for future sales may require additional technology.</p><p>Exploration, development, and production in the Gulf of Mexico Region are continuing at a rapid pace throughout the Gulf of Mexico. Between January 1, 1980, and April 15, 1981, 197 initial plans of exploration and 165 supplemental plans of exploration were submitted to the U.S. Geological Survey (USGS). During the same period, 107 initial and 131 supplemental plans of development/production were submitted to the USGS. As of May 1981, there were 121 offshore mobile drilling units operating in the Gulf of Mexico.</p><p>Pipelines continue to be the preferred mode of transport for Gulf of Mexico OCS oil and gas production. Pipeline additions to the existing network average 69 miles (111 km) per month. At any given time, numerous pipeline projects are under way in the Gulf of Mexico. To supplement OCS oil and gas production several deepwater port projects, designed to handle imported crude oil, are being planned or constructed in the region. The process of transportation planning in the Gulf of Mexico is done by industry and government through BLM's Intergovernmental Planning Program and its Regional Technical Working Group (RTWG). The RTWG has completed the First Edition Gulf of Mexico Regional Transportation Management Plan.</p><p>The nearshore and onshore facilities in the Gulf of Mexico service both the domestic onshore and offshore oil and gas industry as well as the global market. Most of the major centers along the Gulf Coast, including Houston, Corpus Christi, Galveston, Beaumont, Port Arthur, and Freeport, Texas; New Orleans, Lake Charles, Lafayette, Baton Rouge, Morgan City, and Houma, Louisiana; Pascagoula, Mississippi; Mobile, Alabama; and Port Manatee, Florida, have ties to the offshore industry. A wide array of services and support industries, ranging from small independent vendors to major international manufacturing contractors, can be found within the region. Profiles of selected centers reveal typical industries and patterns of activity that are characteristic throughout the Gulf Coast region.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr81620","collaboration":"Prepared in cooperation with the Bureau of Land Management","usgsCitation":"Havran, K.J., 1981, Gulf of Mexico summary report 2, August 1981: A revision of Outer Continental Shelf oil and gas activities in the Gulf of Mexico and their onshore impacts: A summary report, September 1980: U.S. Geological Survey Open-File Report 81-620, Report: x, 79 p.; 6 Plates: 34.91 x 15.86 inches or smaller, https://doi.org/10.3133/ofr81620.","productDescription":"Report: x, 79 p.; 6 Plates: 34.91 x 15.86 inches or smaller","costCenters":[],"links":[{"id":413813,"rank":8,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1981/0620/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":413812,"rank":7,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1981/0620/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":413811,"rank":6,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1981/0620/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":142942,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1981/0620/report-thumb.jpg"},{"id":413810,"rank":5,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1981/0620/plate-4.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":413809,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1981/0620/plate-5.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":413808,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1981/0620/plate-6.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":413807,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1981/0620/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Alabama, Florida, Louisiana, Mississippi, Texas","otherGeospatial":"Gulf of Mexico Outer Continental Shelf","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -97.53573046304996,\n              26.019482367005608\n            ],\n            [\n              -82.34267159501141,\n              26.019482367005608\n            ],\n            [\n              -82.34267159501141,\n              30.325598976571015\n            ],\n            [\n              -97.53573046304996,\n              30.325598976571015\n            ],\n            [\n              -97.53573046304996,\n              26.019482367005608\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a81e4b07f02db64a1c9","contributors":{"authors":[{"text":"Havran, Kenneth J.","contributorId":40983,"corporation":false,"usgs":true,"family":"Havran","given":"Kenneth","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":159620,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Compared with the background values, pH and concentrations of all major dissolved ions and dissolved, suspended, and streambed metals generally increased in Spencer Creek tributary downstream from the mine. Median dissolved-sodium and sulfate concentrations increased as much as eighteenfold and fourteenfold, respectively , and median dissolved-manganese and suspended aluminum concentrations increased as much as sevenfold and more than twofold. Concentrations of suspended metals decreased more than 50% after installation of sediment ponds by the mine operator. During high streamflow, concentrations of major ions at background and at mined sites on Spencer Creek tributary decreased, but dissolved- and suspended-metal concentrations increased downstream from the mine. South Lake exhibited seasonal stratification and mixing characteristics of other lakes at a similar latitude. However, the bottom 3 feet of the water column demonstrated persistent chemical stratification. Phytoplankton populations of the lake varied seasonally, and the population density patterns resembled those in other lakes at latitudes similar to that of South Lake.

The flash flooding was caused by intense storms on June 30 through July 2. Total rainfall accumulation ranged from 5.8 inches near Ontario to 9.5 inches at La Farge. The resulting flood equaled or exceeded the largest ones recorded since the 1850 's and equaled or exceeded the 100-year flood frequency at the U.S. Geological Survey 's streamflow gages at La Farge and Steuben. Elevation and delineation of the flood are shown on photo mosaics developed from black and white aerial photographs. The 100-mile reach from Wauzeka to Wilton is shown. A summary of the storm conditions causing the flood and an analysis of the rainfall totals, as prepared by the Wisconsin Geological and Natural History Survey, are also included.

This 40-km x 35-km area was chosen for study because it lies within the area of high interest for petroleum development (Lease sales 49 and 59), and because it includes several wells which provide stratigraphic control. This report discusses the results of geologic mapping, using seismic-reflection data acquired in 1978 and 1979. Some initial results from more recently acquired data are included.</p><p>The Continental Slope in the study area has a complex surface with ridges, canyons, and valleys. Three slump or slide features were observed in the heads and on the walls of canyons and valleys, and two slides were identified on an intercanyon area. The identified slumps or slides are found in Quaternary sediments and total about 1.3 percent of the Continental Slope area mapped.</p><p>The slope is generally mantled by less than 2 m of Holocene sediments. Pleistocene sediment (primarily silty clay) is about 450 m thick at the top of the slope and thins to nearly zero or is absent on much of the mid and lower slope, where sediments of Miocene to Eocene age are exposed. Ridges on the midslope (water depths of 800-1,500 m) and parts of the lowr slope (1,500-2,150 m) result primarily from Pleistocene and older deposition. The intervening valleys show evidence of erosion along the deepest parts of their courses. Mid-range sidescan-sonar data show evidence that processes of bottom-current erosion and downcanyon transport of material may be active in the present day.
