上扬子地壳区域性地层岩石物性力学参数与滑动层位关系研究

STUDY ON RELATIONSHIP BETWEEN ROCK PHYSICO-MECHANIC PARAMETERS AND SLIPPING LAYERS OF REGIONAL STRATA IN THE UPPER YANGTZE CRUST

在中下扬子地区地壳区域性滑动层位岩石物性力学参数研究的基础上,对上扬子地区地壳的相应岩层进行了系统的定量测试。其滑动层位各种参量在塑性、韧性和粘性上所表现出特征的规律,在我国南方型数字地层中,具有一定的普遍性和可比性。同时,也揭示了地壳的构造分层性,并可作为上扬子板块浅层地质—地球物理特征分析的重要依据和建库信息。

Based on a study of physico-mechanic parameters of rocks to regional slipping layers in the Middle-Lower Yangtze crust, the relative parameters of rock physico-mechanics to regional slipping layers were systematically and quantitatively determined in the Upper Yangtze crust. The slipping layers indicated a characteristic regularity in the plasticity, ductility and viscosity, which possessed a number of universality and contrast in the digital strata of the southern pattern in China. Likewise, the tectonic layering of the crust was clearly revealed, which should be an important basis, significantly, for the characteristic analysis and an information for establishing digital base of the geology and geophysics of the shallow level in the Upper Yangtze plate tectonics.
