斑岩铜矿的经济意义已为人所共知.我们试图通过探讨数学地质手段在找矿评价中的应用,裨对这类矿床的找矿突破有所帮助.斑岩铜矿是与中一酸性浅成岩浆侵入活动有关的细脉浸染型高一中温热液硫化矿床,在时间和空间上都具有一定发展规律的蚀变矿物晕和地球化学扩散晕.据此,并从已有的认识出发,我们认为斑岩岩体的种类、规模、形态、侵入时间、岩石结构,围岩的岩性、时代、蚀变带组合,以及矿化富集部位、矿石构造、金属矿物组合等成矿地质条件,可以看作是评价斑岩铜矿的地质变量.
The economic significance of porphyry copper deposits has been well known.We have tried to find a breakthrough in the prospecting of these deposits by exploring the application of mathematical geologic methods in prospecting evaluation.The porphyry copper deposits are associated with a Shallow magmatic intrusions related to the high-medium temperature veined sulfide mineralization vein mineralization, both in time and space have certain development patterns of altered mineral halo and geochemical dispersion of halo.Accordingly, and from the existing understanding We consider the type, scale, morphology, time of intrusion, rock structure, lithology of the surrounding rock, age, alteration zone assemblage, mineralization enrichment site, ore structure and metal mineral assemblage etc. Geological conditions, can be seen as a geological assessment of porphyry copper deposits.
