摘要:
      主要介绍了1∶5万高精度重力测量在广东南岭雪山嶂地区地质综合调查中的应用。利用面积性及剖面性重力数据处理和解释所取得的成果,在指导1∶5万地质填图中圈定半隐伏或隐伏岩体、追踪断裂构造、确定地层界线及追索矿(化)体等发挥了重要作用。以成矿地质体、成矿构造和成矿结构面、成矿作用“三位一体”成矿理论指导大宝山矿床外围找矿,圈定了大宝山矿集区含矿建造范围,追踪已知矿段延伸,分析其深部成矿潜力。根据1∶5万重力测量成果,在大宝山矿床外围的北东侧剩余重力正异常部位,成功发现深部厚大铜矿。

Abstract:
      This paper introduces the application of 1∶50 000 high-precision gravity survey in the comprehensive geological survey of the Xueshanzhang area in Nanling, Guangdong, by applying the area and profile gravity data to process and interprete research data. The gravity survey plays an important role in the 1∶50 000 geological mapping, delineating semi-concealed or concealed rock mass, tracking fault structures, and determining stratigraphic boundaries and retrieving ore bodies. The ″trinity″ theory of metallogenic geological body, metallogenic structure and metallogenic structural surface, and metallogeny is used to guide the prospecting of the Dabaoshan deposit, delineate its ore-bearing construction area, track down the extending of known ore sections, and estimate the metallogenic potentials of its deep areas. The result of gravity survey manages to indicate the residual gravity anomaly of the northeast side of the Dabaoshan deposit, where a deep thick copper mine was discovered.
