摘要
生物成矿作用分为生物直接成矿作用和生物间接成矿作用。生物直接成矿作用的标志性结构为生物有机胶体结构，生物间接成矿作用的标志性结构为“矿交代生物”结构。藻菌生物成因的矿床有三类：生物直接成矿作用形成的矿床、生物间接成矿作用形成的矿床、生物直接成矿作用叠加生物间接成矿作用形成的矿床。
Biomineralization is classified into direct and indirect biomineralization.The indicatortexture of direct biomineralization is biological organic colloid texture and the indicator texture of zation is 'mineralized biological'.The organic genesis ore deposits are classified into three types:(1)Preceding stage type:Organic bodies accumulated ores directly andliving beings participate in metallogenic function directly.(2)Subsequent stage type:Induced materials of organisms participate in mineralization.that is indirect ore-forming process for organisms.(3)Two stage type:Organisms participate in ore-forming process directly and indirectly.
