Excerpt from book: A CONTRIBUTION TO THE THEORY OF MINERAL VEINS. By Robert Hunt, F.r.s. Two constants appear to have been established in relation to the phenomena of metalliferous deposits; one is the uniformity of main general direction of the productive lodes, and the other is the influence of the proximity of dissimilar. rocks. It is very desirable that every possible information upon these points should be collected and recorded, as such a record would serve to establish upon yet more certain data the universality or otherwise of these positions. Two hypotheses, or perhaps three, appear to prevail as to the origin of metalliferous veins. One, and that is the least generally adopted, is, that they have a purely igneous origin; that their contents indeed have been sublimed from great depths, and condensed against the sides of the vast fissures through which the vapours made their escape from the profound depths at which they were formed. Another view is, that the fissures now forming mineral veins were the vents through which thermal waters, highly charged with mineral matter, were forced to the surface; that from these hot springs there weredeposited, layer after layer, against the colder sides of the cracks the metalliferous and earthy matters which they held in solution. According to Mr. John Arthur Phillips, this condition can be actually observed going on in some parts of California. Highly silicious waters are forced through rents in the rocks, in which they deposit their silica, usually in the gelatinous condition; and in this soft silica are found particles of iron pyrites, and even gold. The other view supposes waters to have penetrated from above, and that in passing through the rock fissures, which were the natural channels of aqueous circulation, these waters deposited, under...
