| 摘 要： | 贵州遵义地区黄家湾矿是黑色页岩型镍钼多金属元素矿床。镜下观察及电子探针分析首次发现了矿石中红藻囊果及其与各金属硫化物之间密切的共生关系,为生物参与成矿作用提供了证据。结合前人研究结果,认为镍、钼等金属元素的来源及富集可能与藻类生物作用有关。

| Abstract: | The Huangjiawan Ni-Mo polymetallie deposit in Zunyi, Guizhou Province, is of the black shale type. The red algae ascospores and their association relationship with various metallic sulphides were discovered by microscope and electron microprobe for the first time, providing a powerful evidence for the biogenetic mineralization of Ni-Mo polymetal- lie ores in the Lower Cambrian black shales. Combining with the results of predecessors＇ researches, it is considered that the source and enrichment of Ni, Mo and other metallic elements are possibly related to the algal biologic effects. |
