... Abstract The Meikle and Betze/Post orebodies are two Carlin-type, sedimentary rock-hosted, disseminated gold deposits, located in north-central Nevada along the Carlin trend (Fig. 1). They display important differences in size, alteration, sihcification, pyritization, and gold grade. The Post...

...Greg B. Arehart; K. A. Foland; C. W. Naeser; Stephen E. Kesler Abstract The Post-Betze deposit of Nevada is the largest sediment-hosted disseminated gold deposit presently known, both dimensionally and in terms of contained metal. Ore occurs primarily as submicron-sized gold that is disseminated...

Late ore- and postore-stage sulfide minerals (pyrite, orpiment, and stibnite) from the Betze-Post and Meikle deposits in the Carlin trend and from the Jerritt Canyon mining district have Pb isotope characteristics similar to those determined in Getchell and Turquoise Ridge. This observation...
