广东省和平县公和铜多金属勘查区成矿预测与成矿简析

摘要

广东省和平县公和铜多金属勘查区位于河源深大断裂北东段的北西盘，九连山复背斜的东翼。勘查区处于三叠纪车田岩体（花岗闪长岩）与栖霞灰岩、壶天群灰岩、钙质砂岩的接触带上，矽卡岩化强烈，且勘查区内有原生矿体露头、较好的地球物理航磁异常和水化学镍异常等成矿标志，与北部龙狮铁矿有相似的成矿条件，推测为沉积型、矽卡岩型铜，石英脉型铜钨锡矿床。%The copper polymetallic exploration zone in Gonghe, Heping County, Guangdong Province is located in the north-west plate in north-eastern part of deep faults of the Heyuan plate, eastern flank of Jiulianshan anticlinorium. Explo-ration area is in the contact belt of Triassic chetian rock( granodiorite) , Qixia limestone, pot-day group limestone, calcare-ous sandstone, with intense skarn, native outcrop, good geophysical anomalies and aeromagnetic anomalies and other water chemistry nickel mineralization indication.It has the similar conditions with Longshi iron deposit, conceived to be mineral deposit of copper, tungsten, featuring sedimentary type, skarn copper, and copper quartz vein type.
