Semiquantitative emission spectrographic analyses for 64 elements on 62 stream sediment and 71 rock samples from Mill Creek Wilderness Study area, Giles County, Virginia, are reported here in detail. Locations for all samples are given in Universal Transverse Mercator (UTM) coordinates. Brief descriptions of rock samples are also included. Rocks analysed are mostly sandstone. Samples of hematitic sandstone of the Rose Hill Formation and limonite-cemented sandstone of the Rocky Gap Sandstone contain high values of iron; these rocks are submarginal iron resources. Some of the same iron-rich samples have a little more barium, copper, cobalt, lead, silver, and/or zinc then is in average sandstone, but they do not suggest the presence of economic deposits of these metals. No other obviously anomalous values related to mineralized rock are present in the data.

Semiquantitative emission spectrographic analyses for 64 elements on 98 stream sediment and 122 rock samples from Mountain Lake Wilderness Study Area, Giles and Craig Counties, Virginia and Monroe County, West Virginia, are reported here in detail. Locations for all samples are in Universal Transverse Mercator (UTM) coordinates. Brief descriptions of rock samples are also included. Rocks analysed are mostly sandstone. Samples of hematitic sandstone of the Rose Hill Formation and limonite-cemented sandstone of the Rocky Gap Sandstone contain high values of iron; these rocks are submarginal iron resources. Some of these iron-rich samples have a little more barium, copper, cobalt, lead, silver, and/or zinc than in average sandstone, but they do not suggest the presence of economic deposits of these metals. A few samples of Tuscarora Quartzite contain moderate amounts of manganese. These are from a submarginal manganese resource. No other obviously anomalous values related to mineralized rock are present in the data. VML Chip sample, limonite, bedded (?) or replacement of shale; upper Keefer Sandstone. VML Chip sample, light-tan, friable, fine-grained sandstone, dark-brown to black manganese oxide cement locally; upper Keefer Sandstone. VML Oil Chip sample, very pale-orange, friable sandstone, minor dark minerals; Keefer Sandstone. VML Chip sample, 1.5 m, dark-grayish-red, fine-to mediumgrained, hematitic sandstone, minor white and palered clay chips; Rose Hill Formation. Sp. G. 3.07. VML Chip sample, pale yellow-brown, very fine-grained sandstone; upper Tuscarora Quartzite. VML Chip sample, 1 m, light-gray to brown, iron-stained, fine-grained quartz conglomerate; lower Tuscarora Quartzite.

Semiquantitative emission spectrographic analyses for 64 elements on 69 stream sediment samples and for 30 elements on 14 soil and 86 rock samples from • Dolly Sods Wilderness and vicinity, Grant, Randolph and Tucker Counties, West Virginia, are reported here in detail. Locations for all samples are given in Universal Transverse Mercator (UTM) coordinates. Brief descriptions of rock samples are also included. Rocks analysed are sandstone and shale. No obviously anomalous values related to mineralized rock of economic importance are present in the data.
