Recognition of Late Ordovician Yudai porphyry Cu (Au, Mo) mineralization in the Kalatag district, Eastern Tianshan terrane, NW China: Constraints from geology, geochronology, and petrology

Although the Eastern Tianshan terrane in Xinjiang, NW China, occupies a critical position in the Central Asian Orogenic Belt (CAOB), the early Paleozoic tectonic evolution and mineralization history of this terrane remain ambiguous. The Yudai deposit is a newly discovered porphyry Cu (Mo, Au) deposit in the Kalatag district of the Dananhu island arc, a key area containing early Paleozoic rocks in the Eastern Tianshan. This paper reports the...
