Other editions of book Minerals And Rocks: The Elements Of Mineralogy And Lithology For The Use Of Students In General Geology

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

This scarce antiquarian book is a facsimile reprint of the original. Due to its age, it may contain imperfections such as marks, notations, marginalia and flawed pages. Because we believe this work is culturally important, we have made it available as part of our commitment for protecting, preserving, and promoting the world's literature in affordable, high quality, modern editions that are true to the original work.

This is a reproduction of a book published before 1923. This book may have occasional imperfections such as missing or blurred pages, poor pictures, errant marks, etc. that were either part of the original artifact, or were introduced by the scanning process. We believe this work is culturally important, and despite the imperfections, have elected to bring it back into print as part of our continuing commitment to the preservation of printed works worldwide. We appreciate your understanding of the imperfections in the preservation process, and hope you enjoy this valuable book.

This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

They are distinguished by their cleavage, color, softness, solubility in H2S04 and manner of occurrence. They are found as constituents of partially altered igneous rocks, and of schists. Chlorite schists are made up largely of chlorites and quartz (No. 34). The chlorites also fill veins, and form pseudomorphs after other minerals. 101. Leucite (KAl(Si03)2), is an important rock constituent. It occurs almost exclusively in isometric crystals, resembling those of garnet (Fig. 63), or in small round grains. It is white or light gray, with a glassy luster, and a white streak. It is brittle and transparent or translucent, and has a hardness of 5-6 and a sp.gr. of 2.5. Because it easily Fig. 63.--Leucite decomposes, most specimens appear Crystal, white and opaque. Before the blowpipe, leucite is infusible, but colors the flame for K. It is soluble in HC1 with the production of pulverulent silica. Its powder reacts alkaline. Leucite is distinguished from most other minerals by its crystallization. It is distinguished from white garnet (No. 88) by its inferior hardness and from analcite (No. 130) by its infusibility and the fact that it contains no water. Moreover, analcite fails to give the flame reaction for K (p. 144). The mineral occurs principally in igneous rocks, especially lavas that are rich in potash. It has no commercial value at the present time, but it has been suggested that it might be made a source of potash salts. 102. Kyanite, cyanite ((A10)2Si03) or disthene is an abundant component of some schistose rocks. The name, "kyanite", suggests the sky-blue, color noticed in many specime...
