以佛坪穹隆为核心 ,(麻粒岩相 ) -高角闪岩岩相 -低角闪岩相变质相带呈同心环带状依次向外展布 ;研究表明 ,其为加里东 -海西期由于地幔上隆导致基底减压深熔而形成局部隆起 ,并引起上部盖层分层剪切 -滑脱作用过程变质作用所发生 ;变质峰期温、压力分别可达 82 9℃和 0 .75 Gpa。但变质峰期滞后于变形峰期。在变质变形过程中基底的隆升幅度可达 7km～ 8km。反映主造山前隆 -滑构造在复杂造山带演化过程中的重要作用
At the core of Foping dome, the (granulite facies) -high amphibolite lithofacies-amphibolite facies metamorphic belts are successively distributed outward; the study shows that it is the Caledonian-Hercynian As a result of the uplift of the mantle, the substrate was depressurized and deep-buried to form local uplift and caused stratification of stratified shear-slippage process in the upper cap layer. The metamorphic peak temperature and pressure reached 82.9 ℃ and 0.75 GPa . However, the metamorphic peak lags behind the peak of deformation. In the process of metamorphic deformation uplift of up to 7km ~ 8km. It reflects the important role played by the former orogenic uplift-slip tectonics in the evolution of complex orogenic belts
