Therefore, the straticulate dolostone and spatulate dolostones were rapidly formed by direct precipitation from vaporized seawater in tidal platform. 因此，塔里木盆地塔中1井钻遇的下奥陶统藻纹层白云岩与夹层竹叶状白云岩为潮坪环境下，从蒸发海水中快速沉积形成的。
In this paper, the straticulate dolostone and spatulate dolostone in Lower Ordovician strata of Well Tazhong 1 were studied using petrologic and geochemical methods. 本文选择塔中地区塔中1井下奥陶统藻纹层白云岩与夹层竹叶状白云岩作为对象,应用岩石学与地球化学方法对其成因问题进行了研究。
