| 摘 要： | 新疆西准托里成矿带过去是以金矿、铬铁矿为主的找矿区，2001-2004年包古图地区铜矿找矿获重大突破。包古图铜矿与花岗闪长斑岩密切相关．金属矿物成分简单，矿石构造为细粒浸染状和细脉浸染状。矿石品位低、矿化均匀，矿床蚀变组合和分带特征明显，属典型斑岩型铜钼矿。包古图斑岩型铜矿的发现，在西准是首次，并且证明了哈萨克斯坦巴尔喀什斑岩铜矿带东延至中国境内。对西准地区今后的找矿工作将起到重要的推动作用。

| Abstract: | Volcanic-hosted gold and ophiolite-hosted chromite were previously the focus of long-term exploration and research in the Toli ore belt, western Junggar, Xinjiang. In 2001-2004, a major breakthrough was made in copper exploration in the Baogutu area. The Baogutu copper deposit is closely related to Hercynian granodiorite porphyry. The ore has a simple metallic mineral composition and finely disseminated and veinlet- disseminated structures. The ore grade is low, the mineralization is homogeneous and the alteration assemblage and zoning are pronounced. According to the above-mentioned features, the deposit belongs to a typical porphyry copper-molybdenum deposit. The discovery of the Baogutu porphyry copper deposit is the first-ever discovery of a copper deposit in western Junggar. It proves that the Balkhash porphyry copper belt of Kazakhstan extends eastward into the Junggar area of China, which has great significance for advancing mineral exploration in this new prospect area. |
