Abstract：The Lushan copper deposit occurred in the dark gray or black silty mudstone at the bottom of the Xuanwei Formation (P3x), and the volcano breccia hematite bed at the top of the third section of Emeishan basalt (βP3). These ore-host strata with a new ore type were recognized as new copper mineralized horizons in Guizhou Province. The element zoning sequence in the ore-bearing rock from top to bottom is Ti-Cu-Fe, which is in accordance with the characteristics of the weathering and leaching copper deposit from basalt. The geological characteristics of the Lushan copper deposit was summarized by a detailed study, which provided some new ideas for the exploration of the same type copper deposit.
