The results of in situ DRIFTS on propylene oxidation show that the allyl species originated from α-H abstraction of propylene were located at the wavenumbers of 1454 cm~(-1) and 1427 cm~(-1). The rate-determining step is the abstraction of an α-H abstraction from a lattice oxygen linked to a bismuth ion to form a π-allyl intermediate coordinated to a molybdenum ion. The metal-oxo group then attacks the allyl intermediate forming a σ-bonded oxygen-allyl species, which is in a rapid equilibrium with the π- bonded species. The σ-bonded species then transforms to acrolein by further abstraction of α-H. Such species as formate, carboxylate, carbonate transform to deep oxidation products. The acetone was derived from propylene by an enolic species at lower temperatures.

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。
