七十年代以来,国内外斑岩矿床研究人员普遍注意斑岩矿床蚀变和矿化的水平和垂直分带的模式,进而确认斑岩矿床基本上是由以斑岩体为核心呈同心环状分布的蚀变和矿化带的近似直立筒状体组成。由于矿床所处的地质构造位置不同和矿床剥蚀程度不一,使得各个矿床目前表现的经济价值和蚀变一矿化特征有所不同。因此,正确识别斑岩铜(钼)矿床顶部或根部带的特征,对于评价和勘探一个斑岩矿床来说是十分重要的。过去,国外不少学者对智利丘
Since the 1970s, researchers in porphyry deposits both at home and abroad have paid close attention to the horizontal and vertical zoning patterns of alteration and mineralization of porphyry deposits. This confirms that porphyry deposits are basically concentric rings centered around porphyry Distribution of alteration and mineralization of the approximate vertical cylinder composition. Due to the different geological structure and the denudation of deposit, the economic value and alteration-mineralization character of each deposit are different at present. Therefore, the correct identification of the top or root zone of the porphyry copper (molybdenum) deposit is very important for the evaluation and exploration of a porphyry deposit. In the past, many foreign scholars on Chile mound
