Architecture of a 1.38-1.34 Ga granite-rhyolite complex as revealed by geochronology and isotopic and elemental geochemistry of subsurface samples from west Texas, USA

Barnes, Melanie; Anthony, Elizabeth; Williams, Ian; Asquith, George B.

Description

During the evolution of Laurentia, a Mesoproterozoic felsic igneous belt extended from Fennoscandia through Canada to the southwestern United States. This belt, referred to as the granite-rhyolite province in North America, forms much of the west Texas and eastern New Mexico basement. We present data from 41 closely spaced wells in west Texas that penetrated several hundred meters into the southern granite-rhyolite province and provide the first opportunity to develop a three-dimensional view...[Show more]
