Book Description
Excerpt from Geology and Water Resources of the Northern Portion of the Black Hills and Adjoining Regions in South Dakota and Wyoming It is desirable to repeat here the statement made in my previous report that all who study the geology of the Black Hills must feel impressed by the remarkably clear general conceptions of the geologic relations of this region afforded by the survey made by Mr. Henry Newton over a quarter of a century age! In one short season, with many unfavorable conditions for travel ing, be determined most of the broader features and recorded many of the essential details. His posthumous report, edited by Mr. G. K. Gilbert, will always remain a standard work on Black Hills geology. Later studies have added greatly to our knowledge of the details of the stratigraphy and structure, the distribution of the rocks and minerals, and the age of the beds, and have afforded means for a more complete elucidation of the geologic history, especially the physiographic development of the Black Hills region.

Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1897 edition. Excerpt: ...sulphuric acid, or by hydrochloric acid, to give a colorless solution, which, treated with metallic zinc, becomes intensely blue, but soon bleaches on dilution. Characterized by its high specific gravity. Wolfram is often associated with tin ores; also in quartz, with native bismuth, pyrite, galenite, blende, etc. Found in the Etta and Bob Ingersoll Tin mines near Keystone, on Sunday Gulch and near Berne. QUARTZ. H.=7. G.=2.5--2.8. I ustre vitreous, sometimes inclining to resinous; splendent; nearly dull. Colorless when pure; of various shades of yellow, red, brown, green, blue, black. Streak white of pure varieties; of impure, often of the same color but much paler. Composition: pure silica=oxygen 53.33; silica 46.67=100; in massive varieties often mixed with a little opal; silica, impure varieties often contain iron sesquioxide, caleium carbonate, clay, sand and various minerals. Varieties: 1. Crystallized vitreous in lustre. 2. Flint-like, massive, or cryptocrystalline. The first division includes all ordinary vitreous quartz, whether having crystallized faces or not. The varieties under the second are in general acted upon somewhat more by attrition, and by chemical agents, as fluohydric acid, than those of the first. In all kinds made up of layers, as agate: successive layers are unequally eroded. ROSE QUARTZ. Fine specimens of rose quartz of deep rose-red and pink colors are plentiful in many localities of the granitic region around Harney's Peak. The color is due to titanic oxide. Smoky quartz, massive, brownish-black and nearly opaque is found near Keystone. The color is due to organic compounds. Milky quartz, milk-white and nearly opaque. Lustre greasy. Occurs two miles east of Custer Peak on the north fork of Box Elder Creek...
