【摘要】 滨海岩溶具有与内陆一般岩溶区不同的发育机理 ,其过渡带混合溶蚀作用是控制滨海岩溶发育的最主要因素之一。通过七组不同淡水与海水配比的混合溶蚀实验 (封闭CO2 -H2 O系统 ) ,初步得出了过渡带混合溶蚀作用的基本结论 :(1)滨海岩溶区过渡带岩溶发育的基本规律与内陆一般岩溶区岩溶发育规律的基本一致 ,即岩性、结构是控制滨海岩溶发育的最主要因素 ;(2 )滨海岩溶区混合过渡带内碳酸盐岩的混合溶蚀速率大于纯淡水或纯海水中同种岩石的溶蚀速率 ;(3)在不同的CO2 分压条件下 ,滨海岩溶区混合过渡带内碳酸盐岩的混合溶蚀机理不同。更多还原

【Abstract】 The development mechanism of littoral karst differs from inland karst,and the mixture corrosion effect is one of the most important factors which control the development of littoral karst. Through seven groups static experiments carried out in closed CO 2-H 2O system, basic conclusions can be drawn as follows: (1) the basic law of corrosion process in transitional zone of seawater freshwater in littoral karst areas is identical with that of in the fresh water, i.e., lithologic characteristic and rock structure are the main factors which control the development of littoral karst; (2) the mixture corrosion rate of the carbonate rock in seawater freshwater transitional zone is faster than that in fresh water or seawater; (3) the development mechanism of carbonate rock is different at various pressures of CO2 in transitional zone of littoral karst areas.更多还原
