浙江璜山造山型金矿的确认及其意义

Determination and significance of Huangshan orogenic gold deposits in Zhejiang Province

造山型金矿是一种重要的金矿类型,在我国主要造山带都有分布,但在华南地区的江南造山带却少有人研究。通过与典型造山型金矿进行对比,认为浙江璜山金矿在成矿构造环境、赋矿地体变质特征、成矿时间与构造变形、峰期变质时间的关系、成矿元素富集特点以及成矿流体特征上,均与造山型金矿类似,所以确认璜山金矿为典型造山型金矿。璜山造山型金矿的确认对江南造山带区域找矿、璜山金矿深部找矿均具有十分重要的启发和借鉴意义,而且对江南造山带构造演化提供了约束。

Orogenic gold deposit was one of the most important gold types distributed broadly in the main orogenic belts in China, but was rarely studied in Jiangnan orogenic belt in south China. Huangshan gold deposit was located in the east of Jiangnan orogenic belt. It was controlled by NE trending ductile shear zone with translithospheric fracture. The ore bearing geological body was green schist facies rocks. The metallogenic time was synchronization with tectonic deformation. The metallogenic elements were characteristic of single gold enrichment. It was concluded that the determination of Huangshan orogenic gold type was of great instruction significance to the regional mineral exploration and exploration in the deep parts of Huangshan gold deposit.
