| 厘清金沙地区下石炭统九架炉组铝质黏土岩系中锂的富集机制，为锂资源的综合利用与评价提供参考依据。文本评价金沙县坪子上和桶井研究区的锂资源经济价值，研究含铝岩系化学元素在平面和垂向上的分布特征，并分析化学元素的相关性。结果表明，坪子上研究区平面上Li2O呈北高南低、桶井研究区呈西北高东南低。垂向上，Li2O含量在1 000×10-61 999×10-6的样品占分析样品总数的1687%、在2 000×10-62 999×10-6的样品占分析样品总数的542%、在＞3 000×10-6的锂样品占分析样品总数的181%，Li2O在铝土岩中最为富集，其次为粘土岩、铝土矿。Li2O与Al2O3(r=040)、TiO2(r=043)呈正相关，Li2O与SiO2(r=-033)、TFe2O3(r=-020)呈负相关，Li2O与A/S(铝硅比)(r=004)、岩层厚度(r=-007)无相关关系。 |

| 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 evaluation of lithium resourcesThis 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 horizontal and vertical space of aluminium-bearing rock series，and analyzes the correlation of chemical elementsThe results show that lithium resources in the study area have no industrial valueLithium 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 TongjingVertically，samples with Li2O content of 1 000×10-61 999×10-6 accounted for 1687% of the total analysis samples，samples with 2 000×10-62 999×10-6 accounted for 542%，and lithium samples with content of ＞3 000×10-6 accounted for 181%Li2O is the most abundant in bauxite，followed by clay rock and bauxiteLi2O is positively correlated with Al2O3 (r=040) and TiO2 (r=043)，negatively correlated with SiO2 (r=-033) and TFe2O3 (r=-020)，and has no correlation with A/S (aluminum-silicon ratio) and rock layer thickness |
