Clastic sedimentary pob zeb muaj npe raws li cov nplej loj ntawm cov sediment hais

  1. Conglomerate = coarse (64 mm txog > 256 mm), rounded grains.
  2. Breccia = ntxhib (2mm txog 64 mm), angular nplej.
  3. Sandstone = cov nplej loj li ntawm 2 hli mus rau 1/16 hli.
  4. Shale = grains loj li ntawm 1/16 mm mus rau.

Tsuas yog li ntawd, cov piv txwv ntawm cov pob zeb clastic sedimentary yog dab tsi?

Clastic sedimentary pob zeb xws li breccia, conglomerate, xuab zeb , siltstone , thiab shale yog tsim los ntawm mechanical weathering khib nyiab. Chemical sedimentary pob zeb, xws li pob zeb ntsev, hlau ore, chert, flint, ib co dolomites, thiab ib co limestones, tsim thaum yaj cov ntaub ntawv precipitate los ntawm kev daws.

Qhov thib ob, yog av nkos yog pob zeb sedimentary? Lub finer-grained clastic sedimentary pob zeb hu ua shale, siltstone, thiab av nkos . Shale yog ib tug du, thinly txheej pob zeb uas yog tsim los ntawm nplua-grained silt thiab av nplaum hais. Mudstone , qhov zoo tshaj plaws-grained yas pob zeb , tsis zoo txheej, thiab muaj av nplaum ntau dua li shale lossis siltstone.

Kuj Paub, koj tuaj yeem qhia tau li cas yog pob zeb yog clastic?

Clastic Pob Zeb Cov muaj pes tsawg leeg ntawm yas sedimentary pob zeb muab faib ua peb hom - av nplaum / silt, xuab zeb thiab gravel. Av nplaum thiab av nplaum tsawg dua 1/16 hli. Cov no tsis pom qhov muag tsis pom kev. Xuab zeb yog clasts ntawm 1/16 thiab 2 mm nyob rau hauv loj, thiab gravel yog ntau tshaj 2 hli.

Cov pob zeb clastic sedimentary nyob qhov twg?

Clastic Sedimentary Pob Zeb . Clastic sedimentary pob zeb yog ua los ntawm cov khoom ntawm lwm yam pob zeb . Piv txwv li, xuab zeb ntawm lub puam los yog hauv ib lub dune tuaj yeem faus. Nyob rau hauv lub siab ntawm faus, cov xuab zeb yog nias ua ke thiab compacted.
