When local hypergene life prosperous, deposition relative many; Otherwise when the life is in the murky time, relative small; When deposits the many stratum participation internal heat circulation, the surface activity is relatively violent, has the possibility to mean surface Earth life a disaster time, when deposits the few stratum participation internal heat circulation, the surface activity is relatively stable, has the possibility to mean the life an epacme, this is the Earth life periodicity deconstruction and the newborn basic internal reason is at.

当地表生命繁盛时，沉积就相对较多；反之当生命处于低迷时期时，就相对较小；当沉积较多的地层参与内热循环时，地表活动相对猛烈，就有可能意味着地表地球生命的一个灾难期，当沉积较少的地层参与内热循环时，地表活动相对稳定，就有可能意味着生命的一个繁盛期，这就是地球生命周期性毁灭与新生的根本内部原因所在。

First,we have discovered stone artefacts in caves, which have similar features to that were broadly scattered in laterite terraces in Bose basin(0.8 Ma B.P),next study on deposits and fauna will be hopefully contributed to document paleoenvironmental background of early human;Second,early human fossils,Gigantopithecus and mammalian fossils unearthed in Mohui cave provide new evidence of early human origin; Third,after our scientific excavation in Fengshudao site in Bose basin, we have found five pieces of bi-face LCT with 10 tektites and nearly 100 stone artefacts form original laterite deposit.This important discovery is very answerable to international question about stratigraphic suspect of LCT; Fourth, abounding mammallian fossils with human fossils and remains from early Pleistocene to Holocene have been uncovered after systematically excavation in marginal cave of Bose basin.These discoveries are significant to the study on human evolution and establishment of sequence of Quarternary biological-stratigraphic in southern China.

Himalaya, which formed on the basement of the Pan-African orogenic event at about 550 Ma BP and experienced Ordovician to Devonian platform sedimentation, was transformed into to a back-arc extensional-rifted zone at the end of the Carboniferous. The Yarlung Zangbo ophiolitic mélange zone is a Mesozoic back-arc spreading basin corresponding to the Gangdise paleo-island arc zone on the south side of the Tethyan Ocean. The Gangdise zone experienced island-arc orogeny in the Late Paleozoic. The very significant differences in geology on both sides of the Bangong Co-Nujiang suture zone suggest that the suture zone is not only the northern boundary of Gondwanaland and the boundary between the Indian (Yunnan-Tibet) stratigraphic realm and the South China (Qiangtang-Sanjiang) stratigraphic realm, but also the relics of subductional collision and final extinction of the Phanerozoic Tethyan Ocean after the breakup of the Neoproterozoic supercontinent Rodinia. The basic point of study of the collisional orogenic processes of the plateau is the structure and composition of the archipelagic arc-basin tectonic realm of three different stages bounded by three rigid paleocontinental blocks (Gondwanaland, Laurasia and Pan-Cathaysian) and the mutual constraining, transformation and coupling of various material movement forms.
