The Study Of Mineralization In Huangtuliang Gold Deposit, Northwest Hebei

The Huangtuliang gold deposit is located the Chicheng County of Zhangjiagang city, is a large-scale gold deposit. This study has been carried out detailed studies on the regional geology and the local geology of the deposit. In this foundation, the author has the direct and the thorough understanding to the stratums, the magmatic activity, and ore-forming and ore-controlling structures of the Huangtuliang gold deposit. After the office work and the sample analysis, the author unified the original material, elaborated Zhangjiakou-Xuanhua mantle branch structure to the Huangtuliang gold deposit metallogentic control action, reestablishes the metallogentic model of the Huangtuliang gold deposit. The study obtains the understanding is main as follows:1. This article discusses the relation of the stratums and the metallogentic of the Huangtuliang gold deposit. the research demonstrated that, the mining area stratum certainly is not the origin of mineral resources.2. This article studies the relations of the magmatic activity and the mineralization of the Huangtuliang gold deposit, this mining area magmatic rock mainly is Hercynian Shuiquangou- Dnanshan alkali mixed orebody and the Yanshanian granite, the research believed, Shuiquangou - Dnanshan alkali mixed orebody and the mineralization have not directly relations, but Shuiquangou -Dnanshan alkali mixed orebody and metalligenetic materials have the same origin-deep mantle, all is control by alkalinous metasomatic which controls by the ductile shear zone. Yanshanian large-scale magmatic activity and metallogenesis have close correlation.3. This article analyses the ore-forming and ore-controlling structures and the orebody shape .The research demonstrated that, the ore-forming and ore-controlling structures is a ductile shear zone, the orebody shape mainly control by characteristic of the ductile shear zone.4. This article based on the synthetic studies of geochronology and lead, hydrogen, oxygen, sulfur and helium isotopes, and contrasts with the isotope of other gold deposits in Northwestward in Hebei, research mineralization matter origin. The analysis result showed that, the metalligenetic materials mainly came from deep mantle, partial earth crust materials dissolved into metalligenetic hydrothermal in its migration process, including the massive atmospheric water to join.5. Analyses the ingredient of the mineral inclusion to studies how the metalligenetic fluid migrate.6. Applies the mantle branch structure theory, conclude metalligenetic rule of the Huangtuliang gold deposit, establishes the metalligenetic model.7. Collects the grade of each position of Huangtuliang gold deposit, researches the change tendency in dip and in strike of the orebody, and with the foundation of knowing the ore-forming and ore-controlling structures and the orebody shape, analyses the localization in deep and periphery western of orebody.
