自1959年在这里发现斑岩铜矿床以来,到现在已有十多个矿山投产.探明储量32亿吨,平均含铜0.46%,含金0.30克/吨. 矿床产在第三纪闪长岩体的边缘.在吕宋岛北部,沿阿格罗岩基边缘,在马林杜克岛的马欣欣岩株,内格罗岛西北部的岩株以及棉兰老东部的一些岩株的边缘,都有斑岩铜矿产出. 矿床的特征可归纳为以下几点: (1)侵入体的地质年龄在成因上与矿有关,不是上新世就是中新世. (2)与矿有关的侵入岩具有闪长岩的成分.
Since the porphyry copper deposit was discovered here in 1959, more than a dozen mines have now been put into operation, with proven reserves of 3.2 billion tons and an average copper content of 0.46% and a gold content of 0.30 g / t. In the northern part of Luzon, along the edge of the Agro-rock base, the Maoxinxin rock mass on the Marinduque Island, the rock mass on the northwestern Negro Island and some rock masses on the eastern part of Mindanao (1) The geological age of the intrusions is genetically related to the ore, not the Pliocene is the Miocene. (2) With the formation of the porphyry copper deposit, the characteristics of the deposit can be summarized as follows: The mine-related intrusive rocks have the composition of diorite.
