Method for rapidly delineating medium and heavy rare earth prospecting target area in weathering crust model based on geologic body rare earth partition

Abstract

The invention discloses a method for rapidly delineating a medium and heavy rare earth prospecting target area in a weathering crust model based on geologic body rare earth partition, and belongs to the technical field of mineral resource exploration. By collecting and analyzing the rare earth element content of the geologic body, the partition rule of the rare earth elements and the main rare earth carrier secondary mineral characteristics, the medium and heavy rare earth prospecting target area is rapidly determined. According to the method, the occurrence state of the rare earth in the weathering crust and the mineralization potential of the medium and heavy rare earth can be rapidly evaluated only by carrying out a small amount of field verification, a large amount of prospecting cost and manpower investment are saved compared with an existing medium and heavy rare earth target area delineation method, and the method has the advantages of being low in cost, accurate in result, high in efficiency and the like.

Description

technical field [0001] The invention relates to a method for quickly delineating a weathering crust-type medium-heavy rare earth prospecting target area based on the rare earth distribution of a geological body, and belongs to the technical field of mineral resource exploration. Background technique [0002] The rare earth family is a total of 15 elements including lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, and yttrium. Among them, the light rare earth group (lanthanum, cerium, praseodymium, neodymium ), referred to as LREE (abbreviated as L); medium rare earth group (samarium, europium, gadolinium, terbium, dysprosium, holmium), referred to as MREE (abbreviated as M); heavy rare earth group (erbium, thulium, ytterbium, lutetium, yttrium), referred to as HREE (abbreviated H). The combination of medium rare earth group + heavy rare earth is called "medium heavy rare earth" (a...

Problems solved by technology

Although my country's medium and heavy rare earths mainly come from the southern ion-adsorption rare earth mines with Jiangxi, Guangdong, and Fujian as the core production areas, accounting for about 90% of my country's proven medium and heavy rare earth resources and 70% of the remaining medium and heavy rare earth resources, but The fortunes of China's medium and heavy rare earths are still undiscovered
