The crystalline phases of laboratory prepared slags and commercial cover fluxes were studied by using X-ray diffraction and lithofaciesanalysis.
采用X-衍射分析和岩相分析两种物相分析方法，研究了实验室自制覆盖剂和工业覆盖剂的结晶矿相。

Sedimentology plays an important role in the analysis of orogenic stratigraphy and lithofacies, but more attention should be paid to the close relation between sedimentology and tectonics.
沉积学在造山带地层和岩相分析中具巨大作用，应更多强调构造与沉积学的紧密结合。

Reservoir diagenetic features or diagenetic heterogeneties can be characterized by the recognizing diagenetic lithofacies, and their sequence analysis and mapping.
