Sinopsis: This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. Excerpt: ...shear joints. Several tension joints traceable for several hundred feet are shown by uranium-bearing veins (pl. 3; figs. 18, 19), and vertical continuity of tension joints that is greater than that typical of shear joints is best shown by the vein in the Hope adit 3. A few shear joints are traceable along strike for as much as 100 feet, and possibly, one or more of these is as long as the tension joints but is not as readily traceable. An en echelon pattern of tension joints, suggested by several uranium-bearing veins, is apparent only because of the presence of the radioactive material. The distribution of tension joints may actually be random, and the en echelon pattern may be a mere reflection of the selectivity of the mineralization. Examples of the possible en echelon pattern as reflected by uranium-bearing veins can be seen in the Lost Dog-Lucky Stop area (figs. 18 and 20), the Hope adit 3 (pl. 3), and the Big Buck deposit (fig. 21) and, on a smaller scale, at the Blue Bock deposit (Granger and Baup, 1969). SHEAR JOINTS Most joints in the Sierra Ancha region and all prominent joints recognized farther south in Gila County belong to the shear-joint type. These joints generally are nearly perpendicular to the stratification and have planar surfaces; both characteristics result in a fairly constant strike and dip for individual joints even in inhomogeneous rocks. The shear joints rarely are traceable for more than a few tens of feet and are shorter than tension joints in their vertical extent. Most of the joints recorded as fractures on mine maps are shear joints that cut the uranium deposits and are consequently later than them. Not uncommonly a strong shear joint has nearly the same trend as the uraniumbearing vein, but in several deposits (pl. 3, adit 2; f...
