ANALYSIS OF METALLOGENIC GEOLOGICAL LAW AND PROSPECTING PROSPECT OF RARE EARTH DEPOSIRS IN LONGLING-LUXI AREA
The ion adsorption type rare earth deposits in the weathering crust of the Longling-Luxi granite belt mainly occur in the upper fully weathered layer and the middle upper strongly weathered layer of the granite weathering crust.The exposed area of the granite is greater than 1000km2,and the degree of preservation of the weathering crust is high,with a thickness greater than 10 meters.The average total rare earth content in a single project is(ΣREE)0.05％～0.107％,with good ore-forming geological conditions and significant prospecting potential.
