Hauv geology, pob zeb yog ib pob zeb fragment nrog loj dua tshaj 256 millimeters (10.1 nyob rau hauv) inch. Cov me me yog hu ua cobbles thiab pebbles. Hauv kev siv ntau, lub pob zeb loj dhau rau tus neeg txav mus los. Cov pob zeb me me feem ntau yog hu ua pob zeb los yog pob zeb.
Ib yam li ntawd, qhov sib txawv ntawm pob zeb yog dab tsi?
| Lub npe Particle | Qhov Loj | Pob zeb sib sau |
|---|---|---|
| Pob zeb | > 256 hli | Conglomerate los yog Breccia (nyob ntawm qhov sib npaug) |
| Cobble | 64-256 hli | |
| Pebble | 2-64 hli | |
| Xuab zeb | 1/16-2 hli | Sandstone |
dab tsi loj yog cobble?
A cobble (qee zaum ib lub pob zeb cobblestone) yog ib pawg ntawm pob zeb txhais ntawm Udden-Wentworth scale raws li muaj ib tug particle qhov loj ntawm 64–256 millimeters (2.5–10.1 nyob rau hauv), loj dua ib tug pebble thiab me tshaj ib pob zeb.
Cov pob zeb loj hu ua dab tsi?
Pebbles feem ntau xav txog loj dua tshaj granules (2 mus rau 4 millimeters txoj kab uas hla) thiab me dua cobbles (64 mus rau 256 millimeters txoj kab uas hla). Ib pob zeb ua feem ntau ntawm pebbles hu ua conglomerate. Ib lub puam muaj feem ntau ntawm qhov chaw pebbles feem ntau hu ua shingle beach.
