摘要
大田高才坂矿区铜多金属矿体产在昆山向斜东翼早三叠世文宾山组中,明显受北东向断裂控制。矿区内已发现14条铜多金属矿体,形态复杂,总体呈脉状,局部为透镜状产出,矿床成因属于热液充填-交代脉状矿床。矿区南面的石笋崎Cu-Pb-Zn-Mo土壤综合异常中各元素套合紧密,异常规模较大、浓度高,浓集中心清晰,分布连续。认为该区成矿条件较为有利,在昆山向斜西翼及东翼东南部土壤异常区内有望找到隐伏的铜多金属矿体。
The Gaocaiban copper-polymetallic deposit in Datian county was discovered in the three early Triassic Wenbinshan formation and was obviously controlled by NE faulted structures in the east wing of Kunshan syncline. 14 copper polymetallic ores have been discovered. The ore body is complex morphology, exists in veins overall and local in lenticular. The deposit belong to the hydrothermal filling and metasomatic vein deposit with dip angle and continu- ous mineralization. The elements of Shisunqi Cu-Pb-Zn-Mo integrated soil anomaly have a better telescoping in the south deposit. The anomaly is high in concentrations, is countinu- ous in distribution , is large in size and the contraction center of the anomalies is obvious. In conclusion , there are good ore-forming geological conditions in the area, so there will still be the lare-scale hidden copper polymetallic deposit to be found in the soil anomaly area of the west wing and South-East of east wing of Kunshan Syneline.
