Metasedimentary complexes of the Tuva-Mongolian massif: Age, provenances, and tectonic position
A complex problem of dating supracrustal rocks is unavoidable by analysis of tectonic position of polymetamorphic amphibolite and granulite complexes. Geochronological dates are necessary to constrain ages of source rocks and accumulation periods of clastic sediments, while isotopic-geochemical parameters open a possibility to estimate model ages of the crust in provenances. Using the ion microprobe SHRIMPTM (Hiroshima, Japan), clastic zircons from metasediments of the Erzin and Moren complexes...[Show more]
