Book Description
Excerpt from Geology and Ore Deposits of Boise Basin, Idaho Most of the deposits are of moderate size, but the lodes are not uniformly mineralized, and the ore shoots are generally discontinuous and the ore Spotty. The ore shoots are controlled by the effects of movement directed obliquely upward along irregular fissures and by zones of Oblique tension fractures across and along broader zones of shearing. Structural reopening at the end of the base-metal stage of deposition has also been an important factor in the control and distribution Of the precious-metal ore. Thermal zoning has apparently limited the vertical range Of gold and silver deposition, and few of the ore shoots appear to have extended downward for more than 500 feet. The lodes have the general structural, textural, and mineralogical features of the epi thermal precious-metal and base-metal deposits. They were Obviously formed at comparatively shallow depths with the precious-metal ore limited to a narrow vertical range in Spite of favorable structural Openings below the limits of present workable ore bodies.
