【摘要】 研究岩石风化过程中岩石化学成分的变化规律 ,对于进一步研究岩石的风化机理以及岩石的物理力学性质变化过程有着十分重要的意义。本文通过对湘西地区陡山沱组黑色岩石不同风化程度的化学成分分析研究表明 ,岩石中的化学成分将随风化的进行而不断发生变化 ,在一定程度上反映了陡山沱组黑色岩石风化过程中其化学成分的变化趋势。更多还原

【Abstract】 To study the rule of change of rock chemical composition in the weathering process is very important for further research of weathering mechanism and change in rock’s physics mechanics character. This thesis proves the chemical composition of rock will change with its weathering varying and images the tendency of the chemical composition changes by analysis of chemical composition of black rock located in DouShantuo Zu in west Hunan district.更多还原
