Associated type:	Rhyolite
Structure:	Generally northwest-trending, broad to moderate amplitude, anticlinal folds play an important role as structural traps to fluid migration within individual deposits and on a regional scale. The autochthonous carbonate sequences that form the Carlin and Lynn tectonic windows are postulated to be remnant segments of a larger north-northwest-trending regional-scale anticline, with a doubly plunging fold axis that extends from the Gold Quarry deposit northward to the Genesis deposit. In this unified tectonic window model, gold deposits of the north-central and south-central Carlin trend are clustered along both the northeast and southwest flanks of the anticline, while its central portion has been segmented into a Tertiary, postmineral graben by late-phase Basin and Range extensional block faulting., The K and Anne dikes are important dike-filled northeast fault structures in the Genesis Mine area.
Alteration processes:	Zonation patterns for silica-sulfide breccia pipes such as Deep Star exhibit compact envelopes in which silicification and sulfidation are more intensely focused than at other Carlin deposits.
