Cov qauv ntawm cov keeb kwm tsis paub muaj nyob hauv Australia

Australia, New South Wales, Central Coast, Tub Rog Puam. Peb hnub.

Tub Rog Puam yog qhov chaw so nrov rau cov neeg Australian (thiab tsis yog) xwb.

Hmoov tsis zoo, kuv tsis tuaj yeem tiv nrog Google Ntiaj Teb kom tau txais cov kev tswj hwm thiab cov duab meej ntawm ntu no ntawm ntug dej hiav txwv sab hnub tuaj ntawm Australia, nyob txog 115 km (conventionally) los ntawm Sydney.

Qhov chaw txaus siab rau peb yog hais txog ib tug kilometer thiab ib nrab seem nrog peb protrusions nyob rau hauv lub hiav txwv (dej hiav txwv) uas yog heev zoo sib xws rau txhua lwm yam thiab zoo li ib co qauv.

Cov duab qhia meej meej txog cov duab plaub (nrog rau txoj kev sib-angled) ntawm cov pob zeb ntug dej hiav txwv loj.

Feem ntau ntawm cov pob zeb blocks yog sib cais los ntawm ob txheej txheej ntawm ib yam dab tsi zoo li ib tug ntev-corroded hlau qauv hloov los ntawm minerals. Ntxiv kev ua xyem xyav thiab tsis ntseeg welded kev tsim kho yog ntau ntu, ntsug ntawm txoj cai kaum rau saum npoo av.

Hauv kuv lub tswv yim, tsis muaj qhov tsis ntseeg tias cov qauv no yog dag.

Kuj tseem muaj cov lus nug yog ntau lub pob zeb loj loj nyob hauv nruab nrab ntawm cov ledges saum toj no. 200% tias ntuj nthwv dej tsis tuaj yeem cuam tshuam cov blocks ntawm qhov siab thiab nyob deb li ntawd - txuj ci tseem ceeb tsis tshwm sim.

Qhov xwm ntawm pob zeb (los yog muab tub lim) "cov qauv" yog qhov nyuaj rau kev txiav txim siab - nws tuaj yeem yog pob zeb sedimentary lossis (uas yog qhov zoo sib xws) pob zeb. Txawm li cas los xij, raws li tau hais los saum toj no, "cov qauv" yog nyob nruj nreem thiab ntawm txoj cai kaum rau cov txheej txheej ntawm pob zeb (pob zeb?).

Cov qub hlau qhov chaw, crushed thiab deformed los ntawm ib co quab yuam, kuj pom meej meej.

Cov ntsiab lus zoo kawg: muaj kev vam meej, muaj qee qhov kev lag luam loj ntawm ntug dej hiav txwv, tom qab ntawd qee qhov kev puas tsuaj tau tshwm sim, thiab txhua yam tau dhau mus.
