继在新疆谢米斯台地区玄武岩中发现自然铜矿化后，在谢米斯台地区中-酸性次火山岩中发现具有一定规模的斑岩型铜矿化。原生硫化物主要为黄铜矿、黄铁矿和斑铜矿。斑岩型铜矿化主要发育于蚀变的英安斑岩、流纹斑岩和安山玢岩中，矿化岩石中发育强烈的绿帘石化、绿泥石化、碳酸盐化、硅化，局部发育泥化。区内斑岩型铜矿化的发现，表明新疆谢米斯台地区存在两种类型铜矿化，有望取得铜矿找矿新突破。矿化次火山岩及其下部的浅成侵入体可能是区内斑岩型铜矿床找矿评价的重要目标。

The porphyry copper mineralization with a certain scale was found in intermediate-acidic subvolcanic rocks after the discovery of native copper mineralization in basalts of Xiemisitai area, Xinjiang. The primary sulfides are mainly chalcopyrite, pyrite and bornite. The porphyry copper mineralization occurs mainly in the altered rhyolitic porphyry, dacitic porphyry and andesitic porphyrite, and intense epidotization, chloritization, carbonation and silicification and weak argillation occur in the mineralized rocks. This discovery shows that there are two types of copper mineralization in Xiemisitai area, and it is expected that new breakthrough can be made in further copper prospecting. The mineralized subvolcanic rocks and the hypabyssal intrusive bodies beneath the subvolcanic rocks may be the important targets for the further porphyry copper prospecting in Xiemisitai area.
