“五层楼+地下室”找矿模型的适用性及其对深部找矿的意义

Application of "Five levels+Basement" Model for Prospecting Deposits into Depth

在我国地质工作者通过长期实践总结出来的"五层楼"找矿模式的基础上,根据近年来深部找矿的新进展,重点探讨了"五层楼+地下室"找矿模型的适用性。"五层楼+地下室"作为找矿模型不但适合于赣南—粤北地区,也适用于赣中的徐山矿区,在南岭外围的其他矿区如广西的大明山地区和云南的老君山地区也有适用性;除了石英脉型钨矿之外,"五层楼+地下室"模型也适用于钨矿之外的其他矿种,如广西大厂的锡多金属矿区;对于其他类型的矿种和矿床类型,如火山岩型块状硫化物矿床,在某种程度上也不妨理解为倒转的"五层楼+地下室"。当然,"五层楼+地下室"找矿模型的运用也是有条件的,需要结合具体矿区的具体成矿地质条件来综合把握,灵活运用。

The ＂Five levels＂ model is one experical model concluded from the long work by Chinese geologists. Combined with it, authors have tried to discuss the applicability of the prospecting model of ＂Five levels＋Basement＂, based on new development for deep prospecting in recent years. ＂Five levels＋Basement＂ model is not only fit in the Gannan-Yuebei region, but also in the Xushan mining area of central Jiangxi, and other mines in the periphery of Nanling, such as Damingshan in Guangxi and Laojunshan in Yunnan. This model is fit to the quartz-type tungsten ore, and other ore type such as tin polymetallic ore in the Dachang, Guangxi. It’s a kind of reversed model of ＂Five levels＋Basement＂ when it’s used in other type ore and mineral deposits, such as the volcanic-type massive sulphide ore deposits. It is limited by a certain condition when the ＂Five levels＋Basement＂ model is used for prospecting. Therefore, it’s needed to comprehensively combine with the specific metallogenic and geological conditions in a specific ore deposit and used with flexibility.
