| 摘 要： | 高燕锰矿生物标志物特征的研究表明:无论正构烷烃、类异戊二烯烷烃、萜烷还是甾烷特征均反映该矿床生物母源为菌藻类生物.结合该区区域地质背景,推断高燕锰矿形成于深水、还原、偏碱性的盆地斜坡环境.而在高燕锰矿的形成过程中,无论是矿质的初始富集阶段还是最终成矿,生物、有机质均起着极为重要的作用.

| Abstract: | Characteristics of biomarkers were studied in Gaoyan manganese deposit, and the results show that n alkanes, isoprenoids, terpenes and steranes derived mainly from fungi and algae. Considering the regional geology background in Gaoyan, this paper deduced that Gaoyan manganese deposit formed in the basin slope, where presents some characters such as deep water, weak alkalinity and reducibility. During the formation of Gaoyan manganese deposit, biologic activity and organic matter played an important role, whether the enrichment of ore was original or ultima. |
