Sainsbury, C.L., 1974, Geologic map of the Bendeleben 1:250,000 quadrangle, Seward Peninsula Alaska: Golden, CO, Air Samplex, 1 sheet, 31 p., scale 1:250,000, Prepared in cooperation with U.S. Bur. Mines, USGS, and The Mapmakers


Summary:

Sainsbury (1969) first described rocks as of pre-Ordovician age where well exposed in York Mountains in Teller quad, Seward Peninsula, AK. Mapped in Bendeleben quad, Seward Peninsula, AK. Consists of thick unit of thin-bedded argillaceous and dolomitic limestone but intensely schistose on east side of Darby Mountains. Contains thin veinlets of vitreous quartz. Weathers to distinct orange color. Thickness undetermined. Conformably overlies York Slate (new). Underlies folded thrust sheet of Paleozoic limestone converted to dolomite along east side of Darby Mountains. Late Precambrian age is based on stratigraphic relations with York Slate.
