岩浆成矿新探索——小岩体成矿与地质找矿突破

The New Exploration of Magmatic Mineralization: Small Intrusion Mineralization and Geological Prospecting Breakthrough

近年来,地质勘查工作取得的许多突破性进展多与小岩体岩浆矿床密切相关。因此,小岩体矿床作为主要的勘查研究方向之一已经越来越受到关注。在对"两类岩浆小岩体成大矿"(2006)、"小岩体成大矿的范畴及地质属性"(2008),以及"小岩体成矿体系"(2011)研究的基础上,进一步深入阐明小岩体成矿的内涵;完善了2类岩浆小岩体成矿的主要机制和10种成矿类型(基性-超基性岩深部熔离/结晶-贯入机制与中酸性岩头部气、液、矿质聚集成矿机制);指出了大型岩体成矿与小岩体成矿的本质区别及斑岩成矿与小岩体成矿的关系;总结了小岩体成大矿的优越禀赋(小、广、大、高、浅(潜))。同时,提出了在新一轮岩浆矿床勘查工作中应注意小岩体成大矿的典型特征、找矿方向及重点突破的远景区。

Many geological exploration breakthrough are more closely related to the small intrusions depos- its in recent years. The small intrusions deposit that is one of the major exploration research directions has received increasing attention. The author clarified the connotation of small intrusions mineralization, im- proved the main mechanism （the deep segregation/crystallization-penetration mechanism of marie-ultra- mafic magma and the gas, liquid, mineral aggregate in the head of acidic magma mineralization mecha- nism） of the two types of magma of small intrusion mineralization and ten mineralization types. The author also pointed out the essential differences between the large-scale intrusions mineralization and small intru- sions mineralization, and the relationship between the porphyry and small intrusions mineralization, and summarized the superior characteristics （Small, Broad, Large-scale, High, Shallow/Latent） of small in- trusions mineralization. All of the above work on the basis of study about the small intrusions mineraliza- tion of the two types of magma （2006）, The scope and geological attributes of small intrusions mineraliza- tion （2008） and The small intrusions mineralization system （2011）. In addition, we should pay more atten- tion to the typical characteristics, prospecting direction and the important prospecting areas of small intru- sions mineralization in the new round of magmatic deposits exploration work in the future.
