位于甘、川两省交界处的拉尔玛金矿床，赋存于下寒武统太阳顶群，矿区内岩浆活动不强烈，矿床中断裂构造较发育，矿石矿物种类较齐全。矿石中的生物有机地球化学特征表明其为细菌和低等藻类生物体衍生的生物标志物和遗传特征，证明了太阳顶群中的有机质起源于菌藻类生物。矿石中的金属矿物生物组构有生物有机胶体组构和矿交代生物组构，说明生物成矿作用经历了直接成矿和间接成矿，即两轮聚矿作用，菌藻生物的第一轮聚金主要形成矿源层，生物的两轮聚金结果，形成此矿床。
The Lalma gold deposit located at the junction of Gansu and Sichuan Provinces occurs in the Lower Cretaceous solar crest group. The magmatic activity in the ore area is not strong, and the fault structure in the deposit is relatively developed. The types of ore minerals are relatively complete. The bioorganic geochemical characteristics of the ores show that they are biomarkers and genetic traits derived from bacteria and lower algae organisms and demonstrate that the organic matter in the solar crest cluster originates from bacteria and algae. The mineral assemblages of metallogenetic minerals in the ore have bio-organic colloidal structure and ore-bearing biological structure, indicating that bio-mineralization has undergone direct mineralization and indirect mineralization, ie two rounds of mineralization, the first round of bacteria and algae Poly gold formation of the main source layer, bio-gold poly round results, the formation of this deposit.
