本文根据武汉地区不同地貌单元、不同层位钻井岩心砂(岩)样品15组,计2000余粒石英砂,进行扫描电镜表面形态研究和分组X射线能谱元素组合分析,论证本地区自晚第三纪至第四纪全新世的沉积物是近源物质在时空分布上属多次阶段性沉积物环境的产物,即为石英砂脱离母岩—以河网交错为特色的大陆水下环境—风化和成岩作用的模式。在青山这个特定的地貌单元上,于大陆水下环境沉积之后,再次经受较强烈风扬磨蚀作用。
In this paper, based on the different geomorphic units and 15 layers of core sand samples from different layers in Wuhan, more than 2000 quartzite sand samples were collected and analyzed by scanning electron microscopy (SEM) and X-ray grouping of grouped X-ray elements. The sediments of the Triassic to Quaternary Holocene are the products of the near-phase material in the sedimentary environment of multiple stages in space-time distribution, that is, the quartz sand is separated from the parent rock-the continental underwater environment characterized by river network interlacing - Patterns of weathering and diagenesis. On this particular geomorphic unit of Castle Peak, it was once again subjected to a more intense fouling action after the deposition of the underwater environment in the mainland.
