Many common minerals, such as feldspar, develop microscopic pits during weathering. 许多常见矿物(例如长石)会在风化过程中发展出微小坑洞。
The notes describe the common minerals such as quartz and its polymorphs, coesite, tridymite and cristobalite, feldspar, plagioclase, feldspathoids, pyroxenes, amphiboles, etc. 讲稿详细地介绍了火成岩矿物,如:石英及它的同构异形体、柯石英、鳞石英、方石英、长石、斜长石、似长石、辉石、闪石等矿物。
The deformation mechanism of eastern feldspar is dislocation creep in main; but microfractures, twinning and recrystallization are common in western feldspar. 东部长石的变形机制为位错蠕变为主;西部则以微裂隙、双晶与重结晶为主。
