| 中文摘要: |
| 排正金-铅-锌多金属矿床位于三都-丹寨Hg-Au-Sb成矿带南段。为查明矿床成因类型,作者利用地质调查工程成果,对矿床地质、地球物理及化学、矿体及矿石、成矿期次等特征进行分析。分析结果表明,排正多金属矿床受断裂构造控制明显,金属矿化体及异常区多分布主断裂与次级断裂交汇处。矿体多呈脉状、透镜状产出,连续性较差,矿石矿物以自然金、闪锌矿、方铅矿、黄铁矿、黄铜矿、褐铁矿等为主。依据矿石矿物产出状态及共生关系将矿体成矿过程依次划分为构造期、气成-热液期、表生期3个成矿期次,其中气成-热液期为矿床主要成矿期次。结合对成矿带Au、Hg、Sb等矿床的研究,认为排正金-铅-锌多金属矿床为一中低温热液型矿床,且受到后期改造作用影响,研究成果为矿床外围及深部找矿提供了科学依据。 |
| 英文摘要: |
| The Paizheng gold-lead-zinc polymetallic deposit is located in the southern section of the Sandu-Danzhai Hg-Au-Sb metallogenic belt. In order to find out the genetic type of the mineral deposit, by using the results of geological survey engineering, the characteristics of the deposit geology, geophysics and chemistry, ore body and ore, and mineralization period are analyzed. The Paizheng polymetallic deposit is obviously controlled by the fault structure, and the metal mineralization and abnormal areas are mostly distributed at the intersection of the main fault and the secondary fault. The ore bodies are mostly veined and lenticular, with poor continuity. The ore minerals are mainly natural gold, sphalerite, galena, pyrite, chalcopyrite, limonite, etc. According to the ore mineral production status and symbiosis relationship, the ore body’s metallogenic process is divided into three metallogenic stages:tectonic period, gas-hydrothermal period, and epigenetic period. Among the three mineralization stages, the gas-hydrothermal stage is the main mineralization stage of the deposit. Combined with the study of Au, Hg, Sb and other deposits in the metallogenic belt, it is believed that the Paizheng gold-lead-zinc polymetallic deposit is a medium-low temperature hydrothermal deposit, and it is affected by the later transformation. This knowledge provides a scientific basis for prospecting in the periphery and deep of the deposit |
