Page 221 - Missouri ; stockwerk deposits, or bodies of rock impregnated over an irregular space with metalliferous particles ; contactdeposits, or accumulations of ore between the planes of contact of two different kinds of rock-masses. From this last class, we pass by gradual steps to that of the regular unstratified deposits, or mineral veins, the term by which this division may most properly be designated. A mineral vein may be defined as an aggregation of mineral matter, of indefinite length and depth,...
Page 221 - Gash-veins may cross the formation at any angle, but are limited to one particular group of strata, and are peculiar to the unaltered sedimentary rocks.

But even now I have a strong impression that the mineral has been derived from beneath, and that the prospects of deep and continued mining are here as favorable as in other more established mining...
Page 387 - We had not gone far in this uncomfortable manner, when a handsome cave appeared before us, illuminated by the lights in front. It was a square room, with a mud floor and a rock ceiling, along the middle of which was a seam, or vertical crevice, containing galena.
