摘要
研究发现,庐山东南麓中深变质岩系的顶部发育以糜棱岩、构造片岩为主体的顺层韧性剪切变形变质带,其上为滑脱断层和固态流动构造群落带及独具特征的多层滑脱构造形迹群。它们反映了前印支造山期伸展构造作用体制下形成的局部隆起-分层滑脱构造系特征。
Pre-Indosinian local uplift bedding-delamination structure in Lushan mountain area is reported in this paper. This structure, locating upon the positional ductile shear deformational and meta-morphic belt consisting mainly of mylonite and tectonic schist in the top part of the Lushan intermediate-high grade metamorphic rocks, was formed under an extensional setting.
