Figure 13. Supergene alunite dates and geomorphic events in northeastern Nevada. The vertical blue bars indicate the sedimentary lifespans of the basins, simplified from Figure 2. Basin abbreviations: CaB—Carlin basin; ChB—Chimney basin; EB—Elko basin; IB—Ivanhoe basin; IV—Independence Valley. Supergene alunite dates for the Carlin and Getchell gold trends are shown as squares (open, Rain deposit in the northern Piñon Range; solid, all other deposits); data are provided in Table 2. The major geomorphic periods and processes are shown along the right margin.
