gritstone

In the paper, the character of gamma-ray spectrometry is studied upon the simplex element medium, granite, gritstone, limestone and basalt. We can use the variable of S1/ S2 to distinguish the effective atom number so we can distinguish the lithology.

在考虑大气扰动因素下，对单一元素介质、花岗岩、石灰岩、砂岩和玄武岩上空γ能谱的分布特征进行研究，结果表明利用S1/S2的方法可以定性判别岩石的有效原子序数，进而区分岩石性质。

Through the researches, we found that raw material of high silicon low alkali gritstone composition and high alkali clay composition had been calcined under 1400 ℃, so f-CaO in clinker is lower than 1.0%, even lower than this number.

通过试验研究发现，高硅低碱砂岩配料和高碱粘土配料两方案的生料经1400℃煅烧后，熟料中的f-CaO均在1.0%以下，且远低于这个数。

The Artux Formation is dominated by sandstone and siltstone, with minor gritstone layers, indicating a fluvial and distal fan environment. There are terrigenous clastic rocks and carbonate rocks in those Formations.

阿图什组以砂岩和粉砂岩为主夹薄层砾岩，为河流相及冲积扇前缘相。岩石类型有碎屑岩和碳酸盐岩，还有膏盐岩，并夹薄层火山碎屑岩。
