The lower Triassic Himalayan tectonic period is the non-tectonic stillstand period because then grounds do not reach to the denudation-planation level by far, and the denudation-planation surface of the "Daloushan" period aren t quite likely to form.
本文根据碳酸盐岩溶速率及地质年代测定等有关新的研究资料 ,对贵州高原喀斯特区传统地文期提出质疑 ,其论点主要有三 :①下第三纪时的喜山构造期不是构造宁静期 ,当时的地面远未达到剥蚀夷平的程度 ,“大娄山期”剥夷面不太有可能形成 ;②“山盆期”夷平面是由定型于上新世末的喀斯特准平原面 ,经新构造大幅度抬升发展演化而成的 ,由于遭受长期的喀斯特叠加发育及剥蚀降低 ,其地质时代与地貌年代已相差甚远 ,两者不能相提并论 ;③贵州高原喀斯特层状地貌发育 ,至上而下主要有三级 :Ⅰ级夷平程度高 ,称夷平面 ;Ⅱ、Ⅲ级剥蚀夷平程度低 ,称剥夷面。
