Burd Gol granite Massif as a typical product of the Late Cambrian post-orogenic magmatism in the SE part of the Lake Zone, Gobi Altay, SW Mongolia

Popis výsledku v původním jazyce

Intrusion of the Cambrian Burd Gol Granite Massif into the Proterozoic metamorphic rocks of the Zamtyn Nuruu and molasse-like sediments of the Boomyn Khudag culminated the collisional events of the Caledonian evolution in the SE part of the Lake Zone, Gobi Altay, SW Mongolia. The monotonous leucogranites of the Burd Gol Massif have a high-K geochemical signature with an intermediate initial Sr ratio (87Sr/86Sr510 = 0.7064) and rather unradiogenic Nd ( = ?1.5 and ?0.2). The ICP-MS U?Th?Pb dating of monazites and zircons yields intrusive ages between 506.4 ? 5.4 and 513.4 ? 4.3 Ma. The final stage of magmatic activity is documented by the Ar?Ar dating of muscovite from a pegmatite dyke at 485.1 ? 3.2 Ma. The granites intruded and thermally influenced theterrestrial clastic sediments of the Boomyn Khudag Formation. These new data argue against the previously assumed Permian age of the Burd Gol Massif and illustrates the terrestrial evolution in this part of the Lake Zone during the Cambr
