摘要
综述了近年来斑岩铜矿研究领域取得的最新成果。包括 6个方面 :①斑岩铜矿与岩浆的氧化状态有关 ,只有氧化型岩浆才能形成斑岩铜矿 ,并提出了确定岩浆氧化状态的新标志 ;②岩浆中硫和氯的含量、存在状态、溶解度等对成矿有重要控制作用 ;③岩浆能否较早达到水过饱和状态 ,并发生流体相的出溶是成矿的另一个控制因素 ;④俯冲板片释放出的流体对上覆楔形地幔的交代作用是形成含矿岩浆的重要环节 ;④岩浆混合或底侵作用可能在某些斑岩铜矿成矿中起到了重要作用 ;⑤提出了一些新的成矿及找矿标志 。
The progress in research on porphyry copper deposit is viewed, including the following five aspects: (1) It has been proved that porphyry copper deposit is related to oxidized type granite magma. And some new symbol which can be used to determine the redox state of magmas have been established. (2) The contents and solubility of sulfur and chlorine in magma are very important to the mineralization of porphyry copper deposit. (3) It has been illustrated that the earlier reached the oversaturation of water during magmatism, the more advantageous for the mineralizatuon. (4) Mantale metasomatism and magma mixing plays an important role in the origin of the magma which relate to the deposit. (5) Some new kinds of alteration in the deposit, such as magnetite alteration facies and Na Ca alteration, have been discovered and studied.
