This paper takes a marble deposit ore body in northeastern Jiangxi as the research object. Based on the analysis of the geological data of the mining area

combined with the field geological survey and sample test analysis results of the structure

strata and alteration of the mining area

the geological characteristics of the mining area are systematically discussed. The ore body occurs in the stratum where the original rock in the middle section of the Sinian Lantian Formation is basin-lacustrine deposits. The analysis shows that the prospecting mark is the marble of the middle section of the Sinian Lantian Formation; the outer contact zone of magmatic rock and limestone; the structure is relatively uniform

the gray-white marble with a high degree of crystallinity

coarser mineral particles and uniform massive

striped structure can break through to the periphery through the prospecting mark

and expand the mine reserves. After comprehensive analysis

this marble mine was formed by tectonic movement and sedimentary metamorphism in the later period

and belongs to the sedimentary metamorphic marble deposit

which provides a basis for subsequent exploration of the marble deposit.
