中国是世界上矿产资源丰富的国家之一,具有形成超大型矿床的优越地质条件。作者以全国权威性的矿产储量信息和最新的矿产勘查资料为基础,提出了适合我国国情的超大型矿床储量规模划分标准,对我国48种主要矿产的198个超大型矿床进行了全面的统计分析。文中从超大型矿床储量与矿产地之间的数量关系的角度,讨论了不同矿产的储量集中程度和富集能力,就我国超大型矿床对矿床类型的选择性及其时空分布规律等问题进行了讨论,并提出了新的认识。
China is one of the countries rich in mineral resources in the world and has superior geological conditions for forming superlarge deposits. Based on the authoritative information of mineral reserves and the latest mineral exploration data, the author puts forward the criteria for the division of reserves scale of super-large deposits suitable for China’s national conditions and conducted a comprehensive statistical analysis on 198 super-large deposits of 48 major mineral resources in China . In this paper, we discuss the concentration and enrichment ability of different mineral deposits from the perspective of the relationship between the amount of super-large deposit and the quantity of mineral deposits. The paper also discussed the selection of deposit type and its temporal and spatial distribution in China’s super-large deposits Discuss, and put forward new understanding.
