摘要:
新寮岽矿区位于东南沿海火山-侵入岩带西南端,是粤东地区新发现的铜多金属矿床之一。对该矿区与铜矿化关系密切的闪长斑岩和石英闪长岩进行矿物岩石学、SHRIMP锆石 U-Pb定年和地球化学特征研究。结果表明:闪长斑岩和石英闪长岩SHRIMP 锆石U-Pb年龄分别为160.2±1.4 Ma和161.9±1.1 Ma,形成于晚侏罗世,与粤东地区晚侏罗世(161~145 Ma)锡铜成矿期一致; 矿区内各类岩石中均见角闪石、榍石和磁铁矿等; 闪长斑岩属于准铝质高钾钙碱性系列,石英闪长岩属于准铝质高钾钙碱性系列; 闪长斑岩和石英闪长岩富集Rb、U、Ce、Zr、Hf、Y和Nd,亏损K、Sr、Nb、Ta、P和Ti,稀土元素配分曲线呈右倾型,具有明显的中等负Eu异常,轻、重稀土元素分异明显,均具有I型花岗岩的特征; 部分石英闪长岩和矿化石英闪长岩受成矿作用影响,化学成分发生明显变化。
Abstract:
The Xinliaodong copper-polymetallic ore district, located in the southwestern volcanic-intrusive belt of coastal southeast China, is a newly discovered deposit in eastern Guangdong Province. The diorite-porphyry and quartz diorite closely related to copper mineralization were studied using mineral mineralogy, SHRIMP zircon U-Pb dating and lithogeochemical methods. This study yielded a SHRIMP zircon U-Pb age of 160.2±1.4 Ma and 161.9±1.1 Ma for diorite-porphyry and quartz diorite, respectively, suggesting that they formed in late Jurassic. This is consistent with tin-copper mineralization period(late Jurassic, 161~145 Ma)in eastern Guangdong Province. All the rocks in the mining area are found to commonly contain amphibole, sphene and magnetite. Diorite-porphyry belongs to metaluminous, high-K calc-alkaline series. Diorite-porphyry and quartz diorite are enriched in Rb,U,Ce,Zr,Hf,Y and Nd, delepted in K,Sr,Nb,Ta,P and Ti. Right-dipping REE distribution pattern, distinct fractionation between LREE and HREE, and mean negative Eu anomalies are characteristic of I-type granitoid. Some quartz diorite and mineralized quartz diorite were altered chemically by mineralization.
