Excerpt: ... "Vein. The filling of a fissure or fault in a rock, par"ticularly if deposited by aqueous solutions. When "metalliferous, it is called by miners a lode. ... A bed "or shoot of ore parallel with the bedding." "Ledge. A metal-bearing rock-stratum; a quartz vein." Richardson's Dictionary: -- "veins. Lineal streaks in mineral." Encyclopedia Britannica: -- "veins. Fissures or cracks in the rocks which are "filled with materials of quite a different nature from the "rocks in which the fissures occur." I 288. As defined by the geologists.-- Dana: -- "Veins are the fillings of fissures, or of open spaces "made in any way, exclusive of those called dikes, which "are due to intrusions of melted rock.1 Where ores occur "along a vein, it is, in miners' language, a lode."'1 Geike: -- "Into the fissures opened in the earth's crust there "have been introduced various simple minerals and ores, "which, solidifying there, have taken the form of mineral "veins. "A true mineral vein consists of one or more minerals "filling up a fissure, which may be vertical, but is usually "more or less inclined, and may vary in width from less "than an inch up to one hundred and fifty feet or more."3 Le Conte: -- "All rocks, but especially metamorphic rocks, in moun"tain regions are seamed and scarred in every direction, as "if broken and again mended, as if wounded and again "healed. All such seams and scars are often called by the "general name of veins. True veins are accumulations, "mostly in fissures, of certain mineral matters, usually in "a purer and more sparry form than they exist in the "rocks."4 'Dana's Manual of Geology, 4th ed.
