中文摘要:
      逆冲推覆构造最新研究进展包括以下4个方面:1.创立新型逆冲推覆构造几何体系,其主要构造要素为台阶式逆冲断层,强调断裂与褶皱的相互关联性,可划分为断裂与褶皱两个分支系统。2.发展平衡构造剖面的研究方法,用于计算造山缩短量并检验构造解释。3.发现韧性推覆产生糜梭岩、混合岩、花岗岩三位一体的成岩作用和对金矿床的控制作用;清表推覆构造对油气藏的控制作用;浅表台阶式逆冲断层对金属矿藏的控制作用,这种控矿作用
英文摘要:
      Latest advances in thrust structure studies involve:1. Initiate a new structural geometry, characteristized by major element of stepped thrust and by related fold and fault. 2. Develop balanced cross-section to calculate structural shortening and to eximate explanation to structures. 3. Discover diagenesis to mylonite,magmaite and granite by ductile thrusting,and controlling to oil-gas and metallic ore by surficial thrusting. 4. Build accretionary wedge model for fold and thrust belt,to predict geometry of crustal deformation and to explain evolution of continental crust within orogen.
