Npaj tsim tshwm sim ua ntej lig Cretaceous. Cov xwm txheej tom qab deformation tau txuas nrog cov xwm txheej yaig thiab kev tso tawm ntawm lub siab tshaj plaws Cretaceous-Eocene conglomerates (Stefanescu li al., 2006).
Nappe tsim li cas?
Nappes daim ntawv thaum lub pob zeb loj raug yuam (lossis "thrust") hla lwm lub pob zeb loj, feem ntau ntawm lub dav hlau qis qisCov qauv uas tshwm sim tuaj yeem suav nrog cov nplai loj Cov folds recumbent, shearing raws lub dav hlau txhaum, imbricate thrust stacks, fensters thiab klippes.
Nappe thiab fenster tsim li cas?
Nyob rau hauv qhov chaw, yaig tuaj yeem txiav mus rau hauv lub nappe tob heev tias ib ncig lossis elliptical thaj ntawm cov hluas, hauv qab pob zeb raug nthuav tawm thiab tag nrho los ntawm cov pob zeb loj; thaj no hu ua fenster, los yog qhov rais. Fensters feem ntau tshwm sim nyob rau hauv topographic bass los yog tob, V-shaped kwj.
Dab tsi yog tom qab klippe?
A klippe (German rau pob tsuas lossis crag) yog ib qho geological feature ntawm thrust txhaum terrains. Lub klippe yog qhov seem ntawm ib lub nappe tom qab yaig tau tshem tawm qhov txuas ntawm nappetxheej txheem no ua rau muaj qhov txawv txav, feem ntau ze li kab rov tav txhais strata overlying autochthonous strata.
Npaj hauv thaj chaw yog dab tsi?
Napes yog qhov tshwm sim ntawm txoj kev folding mechanism tshwm sim los ntawm kev mob siab rau Kab rov tav thiab qhov tshwm sim compressive quab yuam… Vim muaj kev sib zog txuas ntxiv thiab kab rov tav, lub ceg tawg ntawm lub quav yog pov ob peb kilometers deb ntawm qhov chaw qub. Xws li lub pob txha tawg yog hu ua 'nape'.
