Rare elements and REE are mainly enriched in gray-black trachyte and less in other rocks. In addition, schistosity, pyritization, silicification and carbonation in gray-black trachyte are contributed to enrich rare element and REE. It is suggested that alkaline rocks in Hongyang area have the characteristics of subvocanics, and alkaline rocks in Hongyang and Miaoya areas all came from upper mantle and mixed with some substances of crust. Intrusion of alkaline rocks is related to the occurrence, development and evolvement of the deep rupture zone in the areas.

稀土、稀有元素主要富集于灰黑色粗面岩中，而在其他岩石类型中相对较少，同时岩石的片理化、黄铁矿化、硅化和碳酸盐化对稀土、稀有元素有进一步的富集作用；提出了本区的碱性岩组合具有次火山岩相的特征，讨论了本区碱性岩的成因，认为其与湖北庙垭地区的碱性岩可能均来自上地幔，并不同程度地混染了大陆壳的物质成分，其形成时代与断裂构造带的发生、发展和演化基本同步。

结果表明，这些植物的气孔全部着生在远轴面。7种植物中，玉蕊和绒毛番龙眼的气孔密度较大，滇南红厚壳和团花的保卫细胞最长。

An interbedded sliding zone with fault-slip cleavage in an amygdaloidal basalt thin layer made up the embryo of the main sliding zone and the coupling chemical weathering with physical weathering based on lateral unloading made the interbedded sliding zone get a material prone to slide finally.

褶皱运动产生的构造裂隙与柱状节理的叠加使滑体玄武岩呈现碎裂—镶嵌结构，而沿结构面发生的化学风化形成的腐岩壳使岩体进一步转变为&石夹土&结构，加剧了坡体的时效变形。

According to the evolutionary study of Ostracoda and Conchostraca, a conclusion can be obtained, that environment changes affected and controlled the origination, development and prosperity of the organisms.

构造活动期，生物组合具有低分异度、低丰富度的特点，化石的纹饰结构也相对简单；构造平稳期，湖生生物迅速发展并繁盛，生物组合具有高分异度、高丰富度的特点，化石壳面纹饰结构趋于复杂化、多样化。
