菲律宾铜矿资源比较丰富,总矿石储量达37亿吨,其中斑岩铜矿储量34亿吨,约占总储量的90%.该国也是世界上主要产铜国之一.特别是近十几年来,由于一批斑岩铜矿的发现与开发,使菲律宾铜矿储量和产量成倍增长,铜年产量从1960年的4万吨增到1977年的27.3万吨(增长7倍),跃居世界第七位.为了解菲律宾斑岩铜矿的分布规律及其地质特征,学习他们的找矿勘探经验,以扩大我国铜矿资源找矿途径,根据中菲科学技术合作协定,我组于1978年11月30日至12月30日对菲律宾斑岩铜矿进行了实地考察.现将菲律宾斑岩铜矿的分布概况、地质特征及找矿勘探方法整理如下,供有关地质工作者参考.由于能力所限,文中错误在所难免,敬请批评指正.
The Philippines is rich in copper resources, with total reserves of 3.7 billion tons of ore, of which porphyry copper reserves of 3.4 billion tons, accounting for about 90% of the total reserves of the country is also one of the world’s major copper producing countries, especially in the past decade Due to the discovery and development of a group of porphyry copper deposits, the reserves and output of copper deposits in the Philippines doubled. The annual output of copper increased from 40,000 tons in 1960 to 273,000 tons in 1977 (a 7-fold increase) The seventh in the world.In order to understand the distribution and geological characteristics of the porphyry copper deposits in the Philippines and to learn from their prospecting exploration experience so as to expand the prospecting path for copper resources in China, according to the agreement on scientific and technological cooperation between China and the Philippines, A field investigation of the porphyry copper deposit in the Philippines was conducted from November 30 to December 30. The distribution, geological characteristics and prospecting methods of the porphyry copper deposit in the Philippines are summarized as follows for reference by the geotechnical workers Limited ability, the text error is inevitable, please criticize correction.
