摘要

Wanquansi Ag-Au deposit is located in the Jurassic fault depression at the east part of Zhangjiakou-Xuanhua mantle branch structure. Ag-Au mineralization is posterior to 101.82 to 133.33 Ma. Based on sulfur, lead, oxygen, carbon and noble gases isotopes, it is considered that the mineralizing materials came from the deep mantle. Economic ores were concentrated in the process of mantle branch evolution during Mesozoic. Hydrothermal fluids were dominated by magmatic water with some meteoric water.
