In June 1949, the U. S. Geological Survey in cooperation with the State Engineer of Nevada, as part of the State-wide ground-water studies, drilled a test well on the flood plain of the Humboldt River about 4 miles northeast of Battle Mountain. This well was drilled for the purpose of obtaining information concerning the geologic and hydrologic character of the sediments underlying the flood plain, and the quality of the water in those sediments.

Diamond drill hole exploration of magnetite deposits near Dillsburg revealed a body of diabase beneath the sedimentary rocks in which the deposits occur. The drill core revealed a complete gradational sequence downward from a diabase chill zone through normal diabase, diabase pegmatite, transitional granophyric diabase into granophyre.
New data include the results of petrographic study of a series of specimens from the drill core and 10 new chemical analyses. The sequence, diabase to granophyre, shows progressive increase in alkalies and silica; iron increases into the transitional granophric diabase stage, then decreases in the granophyre. The chemical variations are accompanied by changes in mineralogy which are described in detail.
Field and petrographic studies of other granophyre masses were likewise made.
Possible origins of granophyre from diabase are considered, and it is concluded that crystal differentiation in a large sheetlike intrusion most satisfactorily explains the genesis of granophyre in this region. Prior to complete solidification a residual liquid rich in iron, alkalies, silica, and volatiles collected locally in the upper part of the diabase sheet. In some places fractures released volatile-rich iron-bearing solutions which deposited magnetite in the overlying sedimentary rocks; the remaining liquid crystallized to fine grained granophyre. Elsewhere the volatiles were retained for a longer period; the resulting rock is coarse-grained with numerous miarolitic cavities.
Ring-like outcrop patterns are characteristic of the diabase intrusions in southeastern Pennsylvania. Drill hole and geophysical data indicate that the diabase of these rings has the form of generally discordant curved sheets or basins. Pre-existing fractures or potential lines of weakness may have controlled the sheet-like form, or because of existing pressure conditions the diabase magma was forced to spread laterally rather than rise vertically.

The pits are on the northern edge of Magnet Cove and have been excavated in the oxidized zone of highly weathered and altered volcanic agglomerate. The agglomerate is composed of altered mafic igneous rocks in a matrix of white to gray clay, a highly altered tuff. The agglomerate appears layered and is composed of tuffaceous clay material below and igneous blocks above. The agglomerate is cut by aplite and lamprophyre dikes. Alkalic syenite dikes crop out on the ridge north of the pits.\r\n\r\nAt the present stage of mine development the rutile seems to be concentrated in a narrow zone beneath the igneous blocks of the agglomerate. Rutile, associated with calcite and pyrite, occurs as disseminated acicular crystals and discontinuous vein-like masses in the altered tuff. Thin veins of rutile locally penetrate the mafic igneous blocks of the agglomerate.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr506","usgsCitation":"Kinney, D.M., 1949, The Magnet Cove Rutile Company mine, Hot Spring County, Arkansas: U.S. Geological Survey Open-File Report 50-6, 10 p. :folded map ;27 cm., https://doi.org/10.3133/ofr506.","productDescription":"10 p. :folded map ;27 cm.","costCenters":[],"links":[{"id":95275,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1950/0006/report.pdf","size":"5556","linkFileType":{"id":1,"text":"pdf"}},{"id":147789,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1950/0006/report-thumb.jpg"},{"id":43165,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1950/0006/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac8e4b07f02db67bb4f","contributors":{"authors":[{"text":"Kinney, Douglas M.","contributorId":64642,"corporation":false,"usgs":true,"family":"Kinney","given":"Douglas","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":169514,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":51044,"text":"ofr516 -
