塔中—巴楚地区下奥陶统云灰岩地球化学与成因探讨
Keywords: 塔里木盆地,下奥陶统,白云岩化,成因模式
Abstract:
？塔里木盆地下奥陶统分布着规模巨大的白云岩地层，在这些白云岩地层中已经发现了工业油气藏，勘探潜力巨大。应用岩石学与地球化学方法，对塔中隆起—巴楚隆起内下奥陶统的云灰岩开展成因研究。根据岩石学特征，下奥陶统云灰岩分为低云化程度灰岩、高云化程度白云岩、与中云化程度云灰岩3个端元。地球化学分析结果显示，白云岩与云灰岩δ18o值均比灰岩重约3.5‰，3个端元具有相似的稀土元素配分模式与相似的87sr/86sr同位素组成，表明云化流体主要来源于海水或蒸发海水。云灰岩与白云岩端元表现出富fe、贫u和mo,负ce异常特征，指示其形成于水体偏浅的氧化环境中|相反，灰岩端元表现出形成水体偏深的还原环境中。利用白云岩—海水与灰岩—海水的氧同位素温度计估算岩石形成温度的结果显示，白云岩形成温度高于灰岩，表明温度可能是克服白云岩化动力学障碍的关键性因素。根据流体源、氧化还原条件、形成温度与水体深度的认识，建立了“层状水温控云灰互层模式”|并认为白云岩化主要发生在水体较浅(0~70m),温度相对较高(夏季达30℃)的环境中，对应沉积相主要包括半局限台地潮坪亚相与潮下浅滩亚相|灰岩沉积水体相对较深，温度相对较低(~10℃)，对应沉积相主要为半局限台地潮下滩或滩间海亚相。
