Problems solved by technology

[0006] 1. This technical means is only applicable to the oil and gas exploration process in oil and gas basins, and it is not suitable for solid mineral exploration in mountainous and hilly areas;
[0007] 2. This technique mainly relies on drilling engineering and high-resolution 3D seismic data for sedimentary microfacies characterization, which is costly and inefficient

Embodiment Construction

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments thereof. The exemplary embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0032] 1. Work background

[0033] The rare earth-rich claystone formation in Weining County, Bijie City, Guizhou Province is exposed at the bottom of the Permian Xuanwei Formation, with layered output and good continuity. On the plane, it is widely exposed in the west and south of Weining, and the north, central and southern parts of Hezhang County are distributed in strips. From northwest to southeast, rare earth-rich claystone formations tend to become thinner. Vertically, it is exposed at the top of the Emeishan basalt and the bottom of the Xuanwei Formation. It is mostly in parallel unconformity contact with the Emeishan basalt formation. There is often a set of purple-re...

Abstract

The invention discloses a rare earth ore prospecting method based on large-scale section sedimentary microfacies analysis, and the steps are as follows: a. to find out the basic geological conditions in the working area, and to understand the regional metallogenic geological background; b. according to the actual geological conditions of the working area , stratigraphic and lithological characteristics, combined with the layout and measurement of large-scale sections in the working area, restore the lithofacies and paleogeographic pattern in the working area, and determine the dominant facies belt of the ore-bearing horizon; c. Combined with the trenching and analysis of the section where the rare earth dominant microfacies developed Drilling verification and delineation of the prospecting target area. The method can quickly and conveniently delineate the prospecting target area, and can solve the limitation of the traditional method, thereby reducing the labor cost and greatly improving the prospecting efficiency.

Description

technical field [0001] The invention relates to the technical field of mineral exploration, in particular to a rare earth prospecting method based on large-scale profile sedimentary microfacies analysis. Background technique [0002] Traditional rare earth deposits can be divided into mineral-type rare-earth deposits and weathered rare-earth deposits. The former is mainly composed of independent rare-earth minerals such as bastnasite and monazite; the latter’s rare-earth elements are mainly adsorbed by hydrated or hydroxyl hydrated ions. Mainly clay minerals. [0003] Sedimentary rare earth deposits in a certain area, as a new type of deposits, occur in the lower part of a certain Permian group, and the ore-bearing formation is a set of gray-white claystones. The area is widely distributed and exposed continuously. Preliminary process mineralogy studies have shown that the content of rare earths is positively correlated with the content of kaolinite in clay rocks, and rare...
