作者对浙江海岸带石英砂所做的电镜分析表明,在不同的沉积环境中石英砂的磨圆程度和表面形态各不相同。河流石英砂磨圆最差,近岸浅海石英砂磨圆程度较潮间带差。本区石英砂表面形态主要有7种:1.贝壳状断口,2.溶蚀孔,3.不规则断块,4.V形痕,5.碟形痕,6.表面弯曲沟,7.硅质沉淀。其中以贝壳状断口、不规则断块、溶蚀孔、硅质沉淀等形态为主。本文还指出了研究石英砂表面形态的意义。
The author of the Zhejiang coast quartz sand made by electron microscopy analysis shows that in different sedimentary environment, the degree of rounding and the surface morphology of quartz sand vary. River quartz sand round the worst, shallow coastal quartz sand abrasion than the intertidal zone. There are seven main types of quartz sand surface morphology in this area: 1. Shell-shaped fracture 2. Dissolved pores 3. Irregular blocks 4. V-shaped marks 5. Dish-shaped marks 6. Surface curved grooves 7. Silicon Precipitation. Among them, shell-shaped fracture, irregular fault block, dissolution hole and siliceous sediment dominated. The paper also points out the significance of studying the surface morphology of quartz sand.
