本文是在“我国大陆中东部基底地层成份分区与金属成矿分区”一文的基础上,进一步讨论金属矿床的成矿物质来源.我们认为,金属矿床的成矿物质有两大来源:一是来自上地幔及地壳深部,称为第一成矿物质来源;二是来自硅铝层下部及有关部分,称为第二成矿物质来源.本文现就硅铝层基底形成后,特别是中生代以来所形成的许多铜、钨、钼、金、铅锌和锑等重要矿床,其成矿物质主要来自硅铝层下部及有关部分的问题进行探讨.
This article is based on the article “Basement Stratigraphic Components and Metal Mineralization Zones in the Middle East of Mainland China,” and further discusses the metallogenic source of metallogenic deposits.We believe there are two main sources of metallogenic materials for metallogenic deposits: one is from The upper mantle and the deep crust, known as the first source of ore-forming materials; the second is from the lower part of the Si-Al layer and related parts, known as the source of the second mineralization.This paper is now on the Si-Al substrate, especially after the Mesozoic The formation of many copper, tungsten, molybdenum, gold, lead, zinc and antimony and other important deposits, the metallogenic material mainly from the lower part of the silicon-aluminum layer and related issues are discussed.
