In the Great Basin, the strike of the<br \/>\nArchean\/Proterozoic suture zone is poorly constrained because it is largely concealed<br \/>\nbelow a Neoproterozoic-Paleozoic miogeocline and basin fill. Two-dimensional resistivity<br \/>\nmodeling of two regional south-north magnetotelluric sounding profiles in western<br \/>\nUtah and eastern Nevada reveals a steep, deep (greater than 10-km depth),<br \/>\nconductive (1 to 20 ohm-m) zone about 40- to 55-km in breadth interpreted to be a major<br \/>\nregional shear zone that may be related to or inherited from the Archean\/Proterozoic<br \/>\nsuture zone. The major shear zone may have formed during Proterozoic rifting of the<br \/>\ncontinent and reactivated during Paleozoic tectonism. The magnetotelluric profiles<br \/>\nsuggest the major shear zone is not manifest by a single structure with a uniform<br \/>\nstrike in western Utah and eastern Nevada. Rather, it appears to be comprised of two<br \/>\nor more broad, deep conductive structures with orientations that vary from westsouthwest<br \/>\nin western Utah to northwest in eastern Nevada and follows the general<br \/>\ntrend of the approximate edge of Archean crust proposed by Reed (1993).<\/p>\n","protected":false},"featured_media":4683,"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\/2357"}],"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=2357"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/media\/4683"}],"wp:attachment":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/media?parent=2357"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product_cat?post=2357"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product_tag?post=2357"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
