|Location and accuracy||This occurrence is on the south side of the foot of Tsina Glacier. It is near the center of the south border of section 17, T. 7 S., R. 3 W., of the Copper River Meridian. This occurrence is probably located to within one-quarter mile. It is locality 79 of Winkler and others (1981 [OFR 80-892-B]).|
Geologic descriptionIron-stained lenses and quartz veins in mafic metavolcanic rocks of the Late Cretaceous Valdez Group contain pyrite, chalcopyrite, galena, and sphalerite (Winkler and others, 1981 [OFR 80-892-B]). The sulfide minerals are disseminated in the mafic metavolcanic rocks and in the quartz veins. The metavolcanic rocks probably represent ocean floor basalts that were accreted with the flysch of the Valdez Group (Winkler and others, 1981 [OFR 80-892-A]).
