Silver Belt-McCabe vein, Galena Gulch area, McCabe, Big Bug District, Bradshaw Mts (Bradshaw Range), Yavapai Co., Arizona, USA

‡Ref.: Anderson, C.A. & S.C. Creasey (1958), Geology and ore deposits of the Jerome area, Yavapai Co., AZ, USGS PP 308: 169-174.

The Silver Belt-McCabe vein was traced as a continuous zone for about 14,000 feet (4.2 km) from a point about 1,500 feet WNW of the Iron King Mine southwestward to the corner of the Jerome area. Northeastward the structure disappears beneath the gravel of the Hickey formation in Lonesome Valley; and southwestward, the vein passes from the Jerome area in the quartz diorite. The strike ranges from N.65ºE. in the southern sector to N.30ºE. in the northern sector; the dip ranges from 70ºNW. to 80ºSE.; and the width ranges from 6 to 15 feet.

The vein is almost entirely within the breccia facies of the Spud Mountain volcanics. Chlorite and probably some sericite, lying withe their basal sections essentially parallel to the strike of the vein, characterize the fissile, sheared zone comprising the vein; whereas the wall rocks, especially those on the hanging wall (west side), are foliated but not fissile, and are characterized by actinolitic hornblende.

The vein structure appears to have been mineralized only locally. The oreshoots occur as lenses or pods that rarely, if at all, occupy the entire width of the vein.
