Analysis on the Enrichment Characteristics of Lithium in Aluminium-bearing Rock Series in Jinsha County
To clarify the enrichment mechanism of lithium in the aluminous clay rock series of the Lower Carboniferous Jiujialu Formation in Jinsha area,and provide reference for the comprehensive utilization and e-valuation of lithium resources.This paper evaluates the economic value of lithium resources in Pingzishang and Bucket Jing research area of Jinsha County,studies the distribution characteristics of chemical elements in hori-zontal and vertical space of aluminium-bearing rock series,and analyzes the correlation of chemical ele-ments.The results show that lithium resources in the study area have no industrial value.Lithium resources are high in the north and low in the south in the Pingzishang,and high in the northwest and low in the southeast in the Tongjing.Vertically,samples with Li2O content of 1 000×10-6~1 999×10-6 accounted for 16.87%of the total analysis samples,samples with 2 000×10-6~2 999×10-6 accounted for 5.42%,and lithium samples with content of>3 000×10-6 accounted for 1.81%.Li2O is the most abundant in bauxite,followed by clay rock and bauxite.Li2O is positively correlated with Al2O3(r=0.40)and TiO2(r=0.43),negatively correlated with SiO2(r=-0.33)and TFe2O3(r=-0.20),and has no correlation with A/S(aluminum-silicon ratio)and rock layer thickness.
