引言本文的目的是评述一些新增加的地质资料和对全世界的斑岩铜矿研究中所得出的最新解释。过去的廿年是发现和研究斑岩铜矿的硕果累累的廿年。在这一时期,除了在不列颠哥伦比亚发现了一大批矿床外,在菲律宾、新几内亚、中美、加勒比群岛和伊朗也找到了一些大型矿床。对矿床的洋细野外研究、板块构造学说的迅速发展、岩浆活动的产生与演化、热液系统的性质,所有这一切均有助于解释斑岩铜矿的成因。本文并非为全面的详细评述,而仪概略地综述板块构造理论和对斑岩铜矿解释的要点。
INTRODUCTION The purpose of this paper is to review some of the new geological data and the latest explanation of the porphyry copper deposits in the world. The past 20 years have been a fruitful 20 years of discovering and studying porphyry copper deposits. During this period, in addition to the discovery of a large number of deposits in British Columbia, a number of large deposits have also been found in the Philippines, New Guinea, Central America, the Caribbean Islands and Iran. The field study of the ore deposits, the rapid development of plate tectonics, the generation and evolution of magmatic activity and the nature of hydrothermal systems all contribute to the explanation of the genesis of porphyry copper deposits. This article is not intended to give a comprehensive and detailed review, but rather an overview of plate tectonics and the main points of interpretation of porphyries.
