摘要

The Yaoling tungsten deposit has two types of tungsten mineralization, i.e., wolframite-quartz veins and scheelite skarn. The ⁴⁰Ar/³⁹Ar age of muscovite formed in the ore-forming period of wolframite-quartz veins is (149.44±0.73) Ma, consistent with large-scale tungsten and tin mineralization in Mesozoic Yanshanian period in South China, and this age represents the ore-forming time of wolframite-quartz vein deposits. The SHRIMP zircon age of the buried biotite plagioclase granite body related to mineralization of wolframite-quartz veins is (158±2) Ma, whereas the SHRIMP zircon age of Baijizhai biotite granite body related to mineralization of scheelite skarn is (158±1) Ma.
