摘要
///Though detailed, systematic geological survey in filed, detailed studied the Qianjin rock body of the previous division of Jiaohe region, Jilin Province, combined with petrological, lithogeochemical characteristics to determine the rock type (medium-grained-fine adamellite). Using LA-ICPMS zircon U-Pb method to get the adamellite emplacement age of (205 ± 5.0) Ma, being roughly equal to Sandaohe alkali-feldspar granite isotopic age (216 ± 3Ma). Meanwhile, the authors detailed studied molybdenum mineralization of central part of Jilin Province-Yanbian region, and determined that the granites and molybdenum mineralization have nothing to do.
