Associated minerals are primary glauberite, halite and terrigenous mud; while calcite is absent or rare. The X-ray diffraction analysis shows that the mud-sized crystalline dolostone has an average CaCO3 mole content of 57.30% and an average degree of order of 0.40, revealing the characteristics of higher calcium content and lower degree of order. It is closely intergrown with glauberite, indicating that the aqueous medium in the depositional environment of mud-sized crystallinedolostone was hypersaline water or dilute brine. The temperature of water in the depositional environment calculated according to the oxygen isotope data averaged 30.5℃ and the minimum homogenization temperature of inclusions in primary glauberite crystals associated with mud-sized crystalline dolomite was 44℃. The two groups of temperature data are close, indicating that the temperature of the water in the paleolake environment during the deposition of mud-sized crystalline dolostone ranged from 30.5℃ to 44℃.

泥晶白云石在阴极发光下呈红色、橙红色，与其伴生的矿物除原生钙芒硝、石盐、陆源泥质外，方解石没有或极少；X衍射分析结果表明，泥晶白云石的CaCO3摩尔含量平均为57.30%，有序度平均为0.40，具高富钙、低有序的特征；与钙芒硝岩的紧密共生，说明泥晶白云岩沉积环境的水介质为高盐度的咸水或淡卤水；根据氧同位素数据计算的沉积环境的水体温度平均为30.5℃，与泥晶白云石伴生的原生钙芒硝晶体中的包裹体均－温度最低值为44℃，这两组温度数据基本接近，表明泥晶白云石沉淀时环境水体的温度大致在30.5-44℃之间。

The experiments show that one portion of amino organic compounds in the shell is changed to the volatilizable amine and the other portion is transformed to the involatile nitrate after pyrogenation.The organic compounds disappear completely at 600℃.They also show that the aragonite phase of calcium carbonate in pearl shell chang with temperature;the aragonite phase transforms to calcite at 500℃, but some of organic compounds is still residual;and calcium carbonate begins to decompose to calcium oxide at 600℃.

实验发现，贝壳中的氨基酸类有机物热降解后部分以胺的形式挥发出来，另一部分则转化为不可挥发的硝酸盐的形式，600℃有机物完全消失；同时，贝壳碳酸钙的文石晶相随温度而变化，500℃时转变为方解石结构，其中仍有部分有机物残留，600℃开始分解为氧化钙。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it.
