THE ACTIVE TECTONTICS ALONG YADONG—GOLMUD,QINGHA—XIZANG PLATEAU AND ITS RELATIONSHIP TO SOCIAL CONSTRUCTIONS |
The active tectonics along Yadang—Golmud, Qinghai-Xizang Plateau mainly refer to Yadong-Yangbajing-Wenquan active tectonic belts, the Himalayan border tilting belts, the Gangdise fault block tilting belts and part of the eastern Kunlun boundary tilting belts. Earthquakes are closely related to the marginal faults of the active tectonic belts, so the seismic belts are consistent with the active tectonic belts. The structures controlling earthquakes are active tectonic bels, and the seismic, structures are boundary fracture belts. Geothermal activity is mainly controlled by the faulting depression zone belt in the arive tectonic belts. The intensity of the geothermal activity is mainly concerned to the intensity of the active tectonics, the mechanic nature of the faulting depression zones and its location in the tectonics. Hydropower resource is mainly controlled by the uplifting of the active tectonics, so the engineering and construction in this area should keep away from the boundary fracture belts or take needed precautions against earthquakes. Geothermal resources may be found and utilized in the north-south faulting depression zone where the active tectonics are intensive nowadays and at the bending or cross-cut parts of tectonics. Hydropower resources are richest at the gorges formed at the intersecting parts of north-south directional active tectonic belts and the Yarlungzangbo River bed. |
