Kalamazoo County comprises an area of 572 square miles in the southwestern part of Michigan. It includes parts of the Kalamazoo, St. Joseph, and Paw Paw River basins, which drain into Lake Michigan. The northern two-thirds of the county is drained by the Kalamazoo River and its tributaries. A small area in the western piart of the county is drained by the Paw Paw River, and the rest, by tributaries of the St. Joseph River. Glacial deposits, containing sand and gravel, form an upper aquifer and a lower aquifer underlying large parts of the county. Areas of high transmissibility and thick saturated deposits are sufficiently localized to be considered as separate ground-water reservoirs having limited areal extent and definite hydrologic boundaries.
Ground-water runoff from the basins constitutes a large part of the streamflow. Hydrograph separation shows that ground-water runoff composed 65 and 73 percent of the discharge of Kalamazoo River at Comstock and 75 and 79 percent of the discharge of Portage River near Vicksburg in 1965 and 1966, respectively. Based on the hydrologic budgets for the same years, ground-water recharge was 9.1 and 9.0 inches in the Kalamazoo River basin and 12.2 and 11.6 inches in the St. Joseph River basin.
Ground-water recharge in the Kalamazoo River basin extrapolated for the 34-year period 1933-66 ranged from 4 to 13 inches and averaged 9 inches. In the St. Joseph River basin average recharge was about 9 inches for the same period.
There is a wide range in runoff in the county. Augusta Creek, Portage Creek near Kalamazoo, and Gourdneck Creek have the highest annual runoff and maintain high yields even during periods of deficient precipitation. Spring Brook also reflects large ground-water contributions to streamflow. Storage in these basins could provide additional water during low flows for municipal and industrial needs.
The primary use of lakes in the county is for recreational and esthetic purposes. Maintaining lake levels is therefore of the utmost importance. Levels at Crooked and Eagle Lakes have been maintained by pumping from lower aquifers. Diversion of water from Gourdneck Creek to West and Austin Lakes has helped in maintaining levels. Several relatively undeveloped lakes could be utilized as reservoirs whose storage could be used to augment streamflow or for water supply.
Water in streams is generally of good chemical quality; however, several streams, including the Kalamazoo River downstream from Kalamazoo, have been degraded by municipal and industrial waste disposal. Water in the lakes is generally of good chemical quality with the exception of Barton Lake, which has been degraded by waste disposal.
There is sufficient surface water available in Kalamazoo County to meet requirements for development of large quantities of water. The total available supply (average discharge of a stream) is about 680 mgd (million gallons per day). The dependable supply (7-day Q2, or average 7-day low flow having a recurrence interval of 2 years) is about 303 mgd. By developing artificial recharge facilities, surface runoff during winter and spring could be utilized to recharge ground-water reservoirs.
Surface-water withdrawal in 1966 was about 58 mgd, of which 33 mgd was withdrawn from the Kalamazoo River. The quantity of water now being withdrawn from the ground and surface sources is small compared to the total that may be obtained in the area through full utilization of these resources.
Mathematical models were used to simulate hydrologic conditions in the ground-water reservoirs and to evaluate maximum drawdowns for periods of little or no recharge. The practical limits of development as determined for the ground-water reservoirs are estimated to be at the following average withdrawal rates: Kalamazoo, 39 .mgd; Schoolcraft, 17 mgd; Kalamazoo-Portage, 24 mgd; and several small reservoirs, 67 mgd. These total 147 mgd. Further development would require additional artificial recharge facilities.
Average ground-water withdrawal in 1966 was about 54 mgd. The Kalamazoo River ground-water reservoir furnished about 28 mgd, the Kalamazoo-Portage ground-water reservoir, about 21 mgd, and the other reservoirs, about 5 mgd. Thus, further development without artificial recharge is estimated to be about 11 mgd in the Kalamazoo River reservoir, 17 mgd in the Schoolcraft reservoir, 62 mgd in the several small reservoirs, and only 3 mgd in the Kalamazoo-Portage reservoir.
The ground water is generally of good chemical quality and is suitable for most uses; however, it is Usually very hard and may contain objectionable amounts of iron. Some deterioration of water quality- has .been observed in several areas because of seepage from stockpiles of industrial minerals.
The presence of many inland lakes, streams having high ground-water runoff, and, in places, relatively undeveloped ground-water reservoirs provides -flexibility in water management.

Haden Tetkik ve Arama Enstitusu (MSA)-U. S. Geological Survey (USGS) Mineral Exploration and Training Project, Subproject 2. Subproject 2 is concerned with aeromagnetic interpretation of MTA's aeromagnetic surveys, and ground investigations of selected aeromagnetic anomalies. This report includes new aeromagnetic maps for the Bolu, Canakkale-Karabiga, Demirkoy, and Orhaneli areas and reviews ground investigations in five areas. Activities for each area are sunmarized below: \r\n1. Bolu area: The aeromagnetic map shows two belts of anomalies related to regional magnetite-bearing formations and a group of discrete anomalies, some of which may reflect significant concentrations of magnetite. To date three of these anomalies have been checked on the ground and at one a metamorphic rock containing 14 percent magnetite was observed. \r\n2. Canakkale-Karabiga area: Ground checks were made of six aeromagnetic anomalies. At one locality (Cakirly-Koyu) 6 km south of Nazmara Sea a small magnetite deposit was found. The magnetic anomaly over the area is 150 meters long, and about 3 meters deep in the center of the anomaly exposed massive magnetite boulders. \r\n3. Demirkoy area: The aeromagnetic map shows only one significant anomaly which was checked on the ground and found to be caused by minor magnetite at an intrusive contact. \r\n4. Ezine area: A ground survey of 4.5 sq km area was made where magnetite boulders are locally present on the surface. No significant magnetic anomaly or iron mineralization were found. \r\n5. Orhaneli area: The aeromagnetic map o# the area showed regional magnetic anomaly patterns related to magnetite in mafic intrusives, ultramafic rocks, and mafic flow rocks. In addition 16 localized anomalies were identified. Most of these anomalies were checked on the ground but no significant iron deposits were found. \r\n\r\nThe largest deposit found was a one-meter wide magnetite vein.

S. Geological Survey (USGS) mineral exploration and training project, for the purpose of increasing the known mineral reserves. Geologic mapping of the mine area indicates that hematite is restricted to argillized, silicified, and pyritized dacite and possibly andesite. Hematite is present as massive replacements, impregnations, disseminations, and fracture fillings. Most of the upper part of the iron deposit consists of a breccia composed mostly of silicifiled dacite fragments in a hematite matrix. The iron deposit was apparently formed in three steps: \r\n\r\n1. Argillation, silicification, and pyritization of the andesitic lava and dacite units as a result of a regional intrusion. \r\n2. Intrusion of the Dere Oren dacite stock, with associated faulting, fracturing, and breccia formation at the surface. \r\n3. Deposition of hematite by oxidation of pyrite, and transfer of iron via fractures and faults by hydrothermal or meteoric fluids.\r\n\r\nThe Eymir iron deposit is a blanketlike deposit on the crest of the Sivritepe-Eymir ridge. It is 1300 meters long, 80 to 450 meters wide, and has an average thickness of 18.6 meters. Drill holes in the deposit show the iron content to range from 32.0 to 57.6 percent, and to average 46.5 percent. Most of the gangue is silica, and an arsenic impurity averaging 0.39 percent is present. Most of the deposit cannot be utilized as iron ore because of low iron content, high silica content, and high arsenic content. \r\n\r\nOre-dressing tests have shown that it is feasible to concentrate the low-grade material, producing a concentrate having increased iron content and reduced silica content. Tests have shown also that the arsenic content of the ore can be reduced substantially by sintering. Further tests and economic feasibility studies are necessary to determine whether an economic marketable iron ore can be produced. If such studies indicate the technical and economic feasibility of utilizing all the Eymir iron deposit, detailed additional studies are recommended including: \r\n\r\n1. A detailed drilling and sampling program to include 60 drill holes averaging 40 meters in depth and detailed sampling of mine dumps. \r\n2. Pilot-plant testing of concentration and sintering procedures. \r\n3. A detailed pre-investment economic feasibility study.","language":"ENGLISH","publisher":"U.S. Geological Survey],","doi":"10.3133/ofr72189","usgsCitation":"Jacobson, H.S., and Turet, E., 1972, Geology of the Eymir iron mine, Edremit, Turkey: U.S. Geological Survey Open-File Report 72-189, ii, 14 leaves :ill., maps ;27 cm.;

The area examine is shown by the distribution of sample localities on the accompanying map. No mineral deposits of economic interest were seen.\r\n\r\nThe terrain is one of broad plains and low hills that extend westward from the base of a prominent erosional scarp which forms the western edge of the Arabian Plateau. Streams cutting headward into the low-dipping massive sandstone of the Plateau have carved deep canyongs with vertical walls, and outliers of the sandstone are preserved as buttes and erosional forms of varied shapes.\r\n\r\nThere are no permanent settlements in the mapped areas. The one road leads up a tributary of Wadi Qaraqir to some date gardens at the base of the sandstone cliffs. A well-travelled caravan route crosses the passes at Al Khuraytah to reach the Plateau H. St. John Philby strongly recommended that a road be constructed through these passes to provide direct access from Tabuk to the Red Sea coast.\r\n\r\nBurton (1878) was probably the first European to visit the area. He was searching for mineral deposits and he also located some Nabatcan ruins. Philby in company with R. G. Bogue, U. S. Geological Survey, explored the scarp in the Wadi Qaraqir valley and drove northwestward to Al Khuraytah pass. The geology of the Wadi Qaraqir quadrangle shown on the geologic map of the Northwestern Hijaz (Brown and others, 1963) was compiled from Bogue's work.\r\n\r\nOur work consisted of making traverses around the hilly area and up accessible wadis. We examined the rocks along the traverse routes and visited target areas that had been selected by examination of aerial photographs. Samples of wadi sediment were collected from fault zones, granite contacts, and areas that showed some evidence of hydrothermal alteration.\r\n\r\nThe work was made possible by the cooperation fo the officials of the Directorate General of Mineral Resources, Ministry of Petroleum and Mineral Resources, who arranged for vehicles and accompanying personnel. We did not have a counterpart Saudi geologist for this portion of our trip.","language":"ENGLISH","publisher":"U.S. Geological Survey],","doi":"10.3133/ofr72196","usgsCitation":"Johnson, R.F., and Trent, V.A., 1972, Mineral reconnaissance of the southern part of the Wadi Qaraqir quadrangle, Saudi Arabia: U.S. Geological Survey Open-File Report 72-196, i, 4 leaves :folded col. map ;27 cm., https://doi.org/10.3133/ofr72196.","productDescription":"i, 4 leaves :folded col. map ;27 cm.","costCenters":[],"links":[{"id":147662,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1972/0196/report-thumb.jpg"},{"id":43025,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1972/0196/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":43026,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1972/0196/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":43027,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1972/0196/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 36,27.5 ], [ 36,28 ], [ 36.5,28 ], [ 36.5,27.5 ], [ 36,27.5 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a80e4b07f02db649869","contributors":{"authors":[{"text":"Johnson, Robert Francis","contributorId":8864,"corporation":false,"usgs":true,"family":"Johnson","given":"Robert","email":"","middleInitial":"Francis","affiliations":[],"preferred":false,"id":169307,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Trent, Virgil A.","contributorId":47381,"corporation":false,"usgs":true,"family":"Trent","given":"Virgil","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":169308,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":12568,"text":"ofr7222 - 1972 - Geologic reconnaissance of the Uzunpinar iron mine and vicinity, Kayseri Province, Turkey","interactions":[],"lastModifiedDate":"2012-02-02T00:06:50","indexId":"ofr7222","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1972","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"72-22","title":"Geologic reconnaissance of the Uzunpinar iron mine and vicinity, Kayseri Province, Turkey","language":"ENGLISH","publisher":"U.S. Geological Survey],","doi":"10.3133/ofr7222","usgsCitation":"Barosh, P.J., 1972, Geologic reconnaissance of the Uzunpinar iron mine and vicinity, Kayseri Province, Turkey: U.S. Geological Survey Open-File Report 72-22, i, 18 leaves :maps (2 col.) ;27 cm., https://doi.org/10.3133/ofr7222.","productDescription":"i, 18 leaves :maps (2 col.) ;27 cm.","costCenters":[],"links":[{"id":146242,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae0e4b07f02db688363","contributors":{"authors":[{"text":"Barosh, Patrick James","contributorId":42184,"corporation":false,"usgs":true,"family":"Barosh","given":"Patrick","email":"","middleInitial":"James","affiliations":[],"preferred":false,"id":166351,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70112313,"text":"70112313 - 1972 - ERTS and EROS","interactions":[],"lastModifiedDate":"2017-03-27T14:15:16","indexId":"70112313","displayToPublicDate":"1990-06-12T14:26:00","publicationYear":"1972","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1829,"text":"Geotimes","active":true,"publicationSubtype":{"id":10}},"title":"ERTS and EROS","docAbstract":"In June the National Aeronautics & Space Administration is to launch its first experimental satellite designed to view the Earth systematically with remote-sensing instruments that will provide new information about our resources and environment.
