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.
