摘　　要：通过对白石溪锰矿地质特征、矿石特征、矿物组分、矿物的形成途径、成矿古地理、同位素的研究分析,认为白石溪锰矿的形成是发生在晋宁运动后,低纬度暖温带—亚热带气候条件下。在潮坪相的潮间带,藻类生物在生长繁衍过程中大量吸取或吸附了母液中的Mn2+,等藻类生物死亡后锰则沉积成矿。在研究的基础上初步建立了锰矿成矿模式。Based on the study of geologic features, ore characteristics, mineral components and mineral formation process, paleo- geographic environment of ore - forming and isotope analysis on Baishixi manganese ore, it is concluded that the Baishixi manganese ore deposit was formed in the age of post - Jinning tectonic movement and in the warm temperate zone and sub - tropical zone located in lower latitude areas. In intertidal zone of the tidal flat depositional facies, the algae creatures sucked or absorbed Mn2＋ from mother so- lution during their growth and propagation, and then manganese deposited after the algae was dead. Finally the metallogenic model of manganese ore deposit was initially been built according to the above - mentioned studies.
