Abstract:

文石海底沉淀是地球早期大气高CO2浓度、海洋贫氧条件下,CaCO3过饱和而直接沉淀于海底所形成的自生碳酸盐,可反映古海洋贫氧状态。对华北中元古界雾迷山组(ca1.50~1.45Ga)碳酸盐岩的研究发现:潮下带下部黑色纹层石由针状文石假晶等厚层与微生物席层交互堆叠而成;潮下带中部凝块石白云岩(A单元)主要由针状文石假晶形成的环带或扇状集合体包裹有机质团块所组成,少见碳酸盐微粒。潮下带上部—潮间带下部纹层白云岩(B单元)以自然沉淀的碳酸盐微粒为主,含少量等厚层和扇状、葡萄状文石假晶集合体,以及以孔洞充填形式产出的针状文石假晶。而潮坪成因的泥晶白云岩(C单元)则完全由含有石盐假晶和微生物席裂痕的泥晶质微晶白云岩组成,不含针状文石沉淀。对构成雾迷山组典型副层序基本单元的氧化还原敏感元素比值分析显示:由C单元至A单元,V/Th、Mo/Th、U/Th值逐渐增大,在A单元可能达贫氧富集程度。研究表明,在雾迷山组沉积期,华北陆表海潮下带中部及其以下可能长期处于贫氧状态,而潮下带上部则处于氧化状态,氧化—还原界面接近于正常浪基面底。这个认识对进一步了解中元古代海洋条件、生物与环境相互作用过程及烃源岩勘查具有重要意义。
