Abstract: In recent years,the extraordinary enrichment of lithium in the ore-bearing rock series of karst bauxite(clay) deposits has attracted more and more attention,and relevant research has been carried out in Guizhou,Guangxi and other places.The reserves of karst bauxite(clay) deposits in Henan are in the forefront in China,but the research on associated lithium is relatively weak.Through the analysis of 170 samples from 10 mining areas of the main bauxite(clay) metallogenic area—Sanmenxia-Mianchi-Xin’an bauxite(clay) metallogenic area in Western Henan,and based on the study of regional paleogeography,it is considered that lithium may be adsorbed in the clay mineral of montmorillonite and more easily enriched in the coastal environment;the lithium content in Zhang-yaoyuan-Xiaye metallogenic belt is generally high,which is an ideal area for further prospecting.
