| 摘 要： | 作者提出了一个较完善的生物礁定义。在湘西南洞口—城步确定了十个生物礁;列举了典型礁相剖面并阐述了礁体特征;提出六种生物礁成矿作用。环礁内的城步铺头黄铁矿床成因类型,属于礁控半闭塞泻湖沉积矿床。后来（1979—1980）鉴于这类矿床的独特成矿作用和巨大经济价值,提出礁控成矿论、礁控矿床和生物数学地质等概念来指导找矿。

| Abstract: | The author proposes a well complete definition of reef, and first determines ten reefs of southwestern Hunan and their typical reef-facies sections, and finally, six mineralizing processes of reef are involved. These reefs constituted an uncontinued atoll. The Putou pyrite deposit of Chengbu county within this atoll belongs to reef-control sedimentary deposit of half-enclosed lagoon in genetic type. The studies followed prove the characteristic mineralization ( material source) and the big economic value of these deposits. In contrast with the stratabound theory the author proposes the terms of reef-control mineralization theory, reef-control ore deposits and biomathematical geology in order to prospect ore deposits. |
