In molybdenum-bearing sandstone of Muchuan County, the molybdenum of over 94% is existed in the form of mineral, only less molybdenum then 6% is existed in form of ionic sorption in the carbon-debris. Muchuanite, a new mineral discovered in 1981, occupies most of molybdenum-minerals.Molybdite formed by the oxidation of muchuanite is quite rare.

The authors selected zircon, tourmaline, quartz and feldspar from 67 samples of different facies on the coast of Guangdong for ultrastructural observation with a magnification from 300 to 10,000 under an electron scanning microscope. It has been found that the mineral grains vary ultra-morphologically from place to place, suggesting the influence of different environmental factors. The grains from rivers mostly show simple but irregular collision pits, some being disc-shaped or desquamated, which probably resulted from physical erosion. The exposed areas have yielded rounded grains covered with mini-pores, fissures and funnel-shaped corrosion pits, suggesting a physical erosion together occasionally with chemical corrosion. The morphology of the rounded grains from some periodically exposed facies zones, e.g. intertidal zone, is varied, assuming shell-or honeycomb-shaped mini-pits, small directional striae, curved fissures, V-shaped corroded pits and some SiO_2 precipitates, which are considered to have been formed by physical erosion in combination with chemical corrosion. An equally complicated texture was also found at the surface of the mineral grains from the underwater zones. It is characterized by honeycomb, corroded pits, irregular or parallel fissures, curved steplike and funnel-shaped corroded pits as well as SiO_2 precipitates. This texture is probably a product of chemical corrosion associated with a joint pbysicalchemical corrosion. All these characters seem to indicate the origins of different facies zones in this particular coastsl area.

作者选择了67个分布于不同海岸相带及近海河流环境表层碎屑沉积物中的锆石、电气石、长石、石英四种矿物,用扫描电境放大300至10000倍观察分析其表面结构特征。观察分析发现,不同环境下的矿物表面结构特征有一定区别。这些区别主要由不同环境因素造成。河流环境的矿物表面结构简单,由物理作用造成;海岸环境的不同相带,矿物表面结构特征比较复杂,但程度有所不同。其特征主要取决于物理作用和所迭加的化学溶蚀作用。热带、亚热带海水对矿物的化学溶蚀和改造十分重要。
