Previous studies in the La Noria-Las Calaveras area have proposed that the entire complex was deformed in the greenschist facies during a Late Devonian (Mixtecan) orogeny; based on a U-Pb lower intercept age of ~370 Ma for the La Noria granite, interpreted to have syntectonically intruded the complex’s uppermost unit, the Tecomate Formation, during this event. As a result of structural, geochemical and geochronological reassessment of the area, however, it is concluded that the complex records Late Devono-Mississippian, Early Permian and Triassic (?) greenschist facies deformational events. This finding affects traditional Paleozoic tectonic models for the Acatlán Complex, by suggesting that the complex’s tectonothermal evolution coincides with the closure of the Rheic Ocean during the final assembly of Pangea.</p> 2006-10-03 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1151434573 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1151434573 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
