摘要
古丈县烂泥田锰矿位于震旦系下统湘锰组下段黑色岩系中,成矿受武陵陆隆边缘拗陷之半局限盆地控制,形成于古陆边缘近岸的海湾深湖中,矿石富含有机碳和藻类生物化石.研究表明,菌藻类生物与成矿关系极为密切,矿床属化学-生物化学沉积矿床.
The Lannitian manganese deposit is hosted in the black rock series of Xiang Meng formation in lower Sinian, and its metallization was found to be controlled by the semi-restricted basin at the marginal depression of Wuling continental upwarping. The deposit was formed in the sea-coastal lagoon at the old-land margin, and is rich in fossil bio-algae and organiccarbon. The investigation indicated that the metallogenesis was closely related with the microbe-algae, therefore the deposit is believed to be a chemical-biochemical sedimentary one.
