1.The basin tectonic model: it is intermont basin during late Jurassic to early Cretaceous, developed into faulted-lacustrine basin in Eogene, and evolved into depression in Neogene and Quaternary.
2.On period sequences of modern mountain landslide and ground subsidence hazard of Weihe River basin
3.If a strenuous effort is not made to secure all the necessary conditions, indeed even if one of these conditions is missing, disasters like the loss of Nanking and other places are bound to be repeated.
4.Half convinced, the man raised another question that whether the ground would cave in.
5.Based on the large scale volcanism and the thickness of cenozoic group rapid increased from the north and south side of Leiqiong fault depression to the Qiongzhou strait,combining with the results of geophisical prospecting in strait areas,contributing factor for the rift valley of Qiongzhou strait is discussed,which can caused by the uprush of upper mantle materials.
6.The problems of geo-environment mainly include ground fissure, loess wet-frame , sand soil fluidity, water contamination, geochemistry abnormity(including F, G r 6+ ).
8.In the overlap part of the two main faults, the left-lateral strike-slip movement of them in Miocene Epoch formed the rhomboid and graben downfaulted Big Jinggu Basin the original basin of the Jinggu basin.
9.Studies have made the following conclusions that the concentration places of mineral deposits in Qinling Dabashan area in Shaanxi are mainly distributed in the depressed places of the mantle uplift zones and the contact portion between the mantle and the mantle col and the basement uplift places of pre Cambrian period, secondly near the deep seated big faults of the Caledonides Indosinides.
10.I pick my way through the wet grass, my feet sinking into the saturated soil.
