沙溪斑岩型铜(金)矿床地处长江中下游成矿带,位于庐枞盆地西北部约10 km处,郯庐断裂带南侧,是一个大型的多金属矿床。目前已探明Cu资源量超过100万吨,Au资源量超过33吨。区内侵入岩广泛发育,主要为石英闪长斑岩、黑云母石英闪长斑岩、细斑闪长斑岩,其次还有辉绿岩脉等后期脉体发育,局部闪长玢岩破碎,形成角砾岩。矿区内这一套闪长岩类是主要的赋矿岩石,前人的研究认为他们属于埃达克质
Shaxi porphyry copper (gold) deposit is located in the middle and lower reaches of the Yangtze River metallogenic belt, located in the northwest of Luzong basin about 10 km, south of Tanlu fault zone, is a large polymetallic deposit. At present, it has been proved that the amount of Cu resources exceeds 1 million tons and the amount of Au resources exceeds 33 tons. The intrusive rocks in the area are widely developed, mainly quartz dioritic porphyry, biotite quartz diorite porphyry, diorite porphyrite, followed by diabase veins and other late veins development, local diorite rock broken, Formation breccia. This set of diorites in the mining area is the major ore-hosting rock, and previous studies suggest they belong to the adakitic
