摘要
研究通过对吉根锰矿常量元素、微量元素及稀土元素特征的分析,发现围岩与矿石敏感元素比值明显不同,反映吉根锰矿形成时的水体为常氧-贫氧条件,少部分锰矿形成于厌氧条件下,而围岩则为贫氧-厌氧的环境特征.对其地区化学特征及物源指示进行探讨,对成矿过程及沉积环境具有一定的指示意义.
Abstract
Through the analysis of the characteristics of major elements,trace elements and rare earth elements in Jigen manganese ore,it was found that the ratio of sensitive elements between surrounding rock and ore significantly are different.It is reflecting that the water body during the formation of Jigen manganese ore was under normal oxygen poor oxygen conditions.A small part of manganese ore was formed under anaerobic conditions,while the surrounding rock was characterized by poor oxygen anaerobic environmental characteristics.Exploring the regional chemical characteristics and source indications has certain indicative significance for the mineralization process and sedimentary environment.
