| 摘 要： | 甘肃北山地区罗雅楚山—大红山一带,赋存青白口纪沉积变质铁矿,由元古宙以来,本区经历了多期次构造变动,形成了现今相互叠置的复杂地质体,其加里东运动及海西运动奠定了本区总体褶皱样式。印支运动发育了逆冲断裂系。最为特色的是燕山运动导致本区大规模由南向北推覆的推覆构造,喜山运动为相对稳定的升降运动。

| Abstract: | Luochuyashan-Dahongshan area in Beishan region of Gansu Province,where metamorphic sedimentary iron deposit occurred in the Qingbaikou Period,experienced structural movements of several stages since Proterozoic Eon when the present complex geological bodies formed.Caledonian and Hercynian orogeny caused the overall fold style of this area.Indonisian movement developed systems of thrust fault.Yanshanian movement is the most special;it leaded the nape structure overridden from south to north.Himalayian moveme... |
