The ratios of Al 2O 3/SiO 2 and kaolinite+illite vs quartz for whole rock indicated the intensities of both chemical weathering and erosion.
研究结果表明 ,全岩的化学蚀变指数 (CIA)值主要代表自然作用下化学风化的强度 ;而硅铝率 (或Al2 O3 SiO2 比值 )和 (高岭石 +伊利石 ) 石英比值在全岩研究中代表化学风化与侵蚀作用的共同强度 ;Al2 O3 SiO2 比值与CIA值的相关关系可以作为区分化学风化作用自然因素变化与侵蚀作用加剧的一种新的分析方法 :当样品CIA值异常偏离趋势线时 ,反映出自然化学风化作用的异常变化 ,而Al2 O3 SiO2 比值的异常偏离则可能反映了表层侵蚀作用的加剧 ;结合当地自然环境和人类活动的特点 ,可以推断人为因素对表层红土剖面地球化学特征变异的干预和对侵蚀作用加剧的贡
Further more, Cl\+- content of river water drops off markedly from upstream to downstream, which just is the showing of feature that chemical erosion on evaporate is strong relatively in river source area under high sea level\|frigid and arid area.
计算表明,长江河源区河水中主要化学成分来自蒸发岩中Na+和Cl-,在河流水化学成分中占比例最大,长江河水中Cl-含量从河源区向下游明显逐渐减小,反应出河源区高寒干旱环境下河流蒸发岩的化学侵蚀作用较强的特征。
