某稀土矿床成因及找矿远景分析

Analysis of Formation Cause and Mineral Exploration of One Rare Earth Deposit

该稀土矿位于扬子陆块区(VI)上扬子古陆块(Ⅵ-2)康滇基地断隆带(VI-2-11)中北部。通过分析研究,区内含矿层主要位于第二喷发旋回玄武岩风化壳中,稀土含量较高、含矿层厚度较大。稀土矿的形成与玄武岩风化程度有直接的关系,岩石风化越完全,稀土含量越高,是一种新的玄武岩风化壳型稀土矿床。矿床的成因类型为以轻稀土富集的玄武岩风化壳型稀土矿床,在该区有可能发现一个中大型稀土成矿远景区。

The rare earth mineral is located in the North Central Part of the Kangdian base fault uplift belt(VI-2-11),upper Yangtze ancient landmass(Ⅵ-2),and Yangtze block area(VI).The ore-bearing layers in the area are mainly located in the second eruptive cycle basalt weathering crust,its rare earth content is high,and the thickness of the ore-bearing layer is large.The formation of rare earth minerals has a direct relationship with the weathering degree of basalt,the more completely the rock is weathered,the higher the rare earth content,it is a new kind of basalt weathering degree type rare earth mineral.The formation type of the deposit is light Rare Earth enriched basalt weathering crust rare earth minerals deposit,it might be a medium-large rare earth mineralization prospect area.
