| 摘 要： | 陕西泾阳-淳化地区奥陶系地层可划分为四个组,自下向上为三山子组、贾汪组、马家沟组、桃曲坡组。其中马家沟组的上段碳酸盐岩特纯,CaO的平均含量>54%,MgO的平均含量<1%,是华北地台其它地区所没有的,构成特大型石灰岩矿床。

| Abstract: | The Ordovician strata in the Jingyang-Chunhua region,Shaanxi may be grouped into four formations,from the base upwards including Sanshanzi,Jiawang,Majiagou and Taoqupo Formations.The carbonate rocks more than 1000 m in thickness in the upper member of the Majiagou Formation are very pure,with the average CaO contents of more than 54%,and average MgO contents of less than 1%.These carbonate rocks constitute the extra-large limestone deposit which is unmatchable on the North China platform. |
