摘要
The Huojihe molybdenum deposit in Heilongjiang Province occurs in the Late Triassic-Early Jurassic granodiorite in the north part of Yichun-Yanshou granite belt.The molybdenite is hosted in the fractures of granodiorite,genetically belonging to veinlet-disseminated deposit type.The ore-bearing granitoid involves mainly granodiorite and monzogranite.The zircon U-Pb dating result of diagenetic age of the granodiorite is 190.3 ±2.4 Ma,suggesting that the mineralization age of the Huojihe molybdenum deposit is Early Yanshanian.
