对承德斜长岩杂岩体中,黑山苏长伟晶岩的紫苏辉石巨晶以及钛磁铁矿矿区的纤闪石化紫苏辉石的透射电子显微镜研究表明:表生作用中,在紫苏辉石的(100)裂理面上会生成诸如滑石、蒙皂石等层状硅酸盐矿物.它们是云辉闪石多体间反应的产物.透射电子显微镜观察到这些矿物由小至大的演变.大多数情况下,这些层状硅酸盐矿物最早生成于紫苏辉石晶体中出溶页片的界面上,成一种菱形状的块体,其边界与紫苏辉石的{210}单形平行.此种菱形状块体可串连成脉状,进而连成片.其生成是受多体反应产物在原多体中成核机制控制的.蚀变作用形成的纤闪石化紫苏辉石的超微结构特征则表明,它是由于云辉闪石多体反应的体反应机制而形成.
In the Chengde plagioclase complex, transmission electron microscopy study of peridotite giganton of Heishan pegmatite in Heishan and stilboraze periclase in the titanomagnetite mining area shows that in the epiphytic process, periclase (100) cleavage planes produce layered silicate minerals such as talcum, smectite, etc. They are the products of the intergranular reaction between ornithubblets, and the evolution of these minerals from small to large is observed by transmission electron microscopy In most cases, these phyllosilicate minerals were first formed on the interface of the dissolution of periclopyrite crystals into a rhombohedral block, the boundaries of which were closely related to the {210} Shaped parallel to the diamond-shaped block can be connected into a series of pulse-shaped, and then even into a sheet. Its formation is controlled by the multi-body reaction products in the original multi-body nucleation mechanism of alteration formed fibula petrochemical purple Su Hui The ultrastructure of the stone indicates that it is formed by the body reaction mechanism of the mullite multi-body reaction.
