Constraints on the Proterozoic evolution of the Aravalli-Delhi Orogenic belt (NW India) from monazite geochronology and mineral trace element geochemistry

Buick, Ian; Clark, C; Rubatto, Daniela; Hermann, Joerg; Pandit, M; Hand, Martin


The timing and extent of polymetamorphism in the Mangalwar and Sandmata Complexes from the Aravalli-Delhi Orogenic Belt of Rajasthan (NW India) remains contentious, with Archaean, Paleoproterozoic and Neoproterozoic events having previously been postulated. Monazite SHRIMP U-Pb and electron microprobe (EPMA) chemical ages obtained from metasediments in the amphibolite-facies Mangalwar Complex show that it was metamorphosed at ca. 0.97-93. Ga, with evidence in one sample for an earlier event at...[Show more]
