The Jidu marble deposit is located in the northern part of the Yanyuan-Lijiang passive con⁃
tinental source of the Yangtze block. The structure is not well developed，the magmatic activity is strong，
and the metamorphism is weak.Through the analysis of regional geological background and geological charac⁃
teristics of the mining area，the geological characteristics and genesis of the deposit are determined.Two mar⁃
ble ore bodies are delineated in the mining area. The ore-bearing strata are the Yangxin Formation of the
Middle Permian. The ore body is large in scale and stable in thickness. Porcelain white marble，beige mar⁃
ble and silver gray marble are developed.Combined with the metallogenic geological conditions and ore min⁃
eral characteristics of the deposit，it is considered that the deposit belongs to marine chemical and biological
sedimentary marble deposit，and the ore-bearing layer has great prospecting potential in the northeast exten⁃
sion direction.
