The<br \/>\nMcAfee thrust fault emplaced a relatively thick (>200 m) sheet of Ordovician Valmy<br \/>\nquartzite (locally termed the McAfee Quartzite) on complexly deformed units of the<br \/>\nRMA (locally termed the Snow Canyon Formation) comprised of the Vinini Formation,<br \/>\nElder Sandstone, and Slaven Chert. The rocks were affected by multiple phases<br \/>\nof deformation during and after the Devonian-Mississippian Antler orogeny, including:<br \/>\nemplacement of the Roberts Mountains allochthon with south-vergent folding<br \/>\nand faulting of the upper and lower plate rocks to the Roberts Mountains thrust; emplacement<br \/>\nof Upper Mississippian (324 Ma) basalt dikes that cross-cut the upper<br \/>\n(allochthonous) and lower (para-autochthonous) plate rocks and south-vergent folds;<br \/>\nemplacement of the McAfee Quartzite; and upright north-trending folding after the<br \/>\ndeposition of Antler overlap rocks. Recognition of this history is required to determine<br \/>\nthe internal structure and thickness of the allochthon and location of high-angle<br \/>\nstructures within it that, respectively, may conceal and localize Carlin-type gold<br \/>\ndeposits in underlying carbonate rocks.<\/p>\n","protected":false},"featured_media":4589,"comment_status":"closed","ping_status":"closed","template":"","meta":{"pmpro_default_level":""},"product_cat":[154],"product_tag":[],"_links":{"self":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product\/2505"}],"collection":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/comments?post=2505"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/media\/4589"}],"wp:attachment":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/media?parent=2505"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product_cat?post=2505"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product_tag?post=2505"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
