Cov txoj cai ntawm qhov qub lateral continuity proposes strata Ameslikas ncua nyob rau hauv tag nrho cov lus qhia kom txog rau thaum lawv thinned mus rau xoom los yog terminated tawm tsam cov npoo ntawm lawv cov thawj phiab ntawm deposition. Qhov no yog peb ntawm cov txoj cai ntawm Niels Stensen (alias Nicolaus lossis Nicolas Steno) (Dott and Batten, 1976).

Kuj paub yog, vim li cas lub hauv paus ntsiab lus ntawm lateral continuity ua hauj lwm?

Cov lub hauv paus ntsiab lus ntawm lateral continuity hais tias cov khaubncaws sab nraud povtseg pib txuas ntxiv mus tom qab nyob rau hauv tag nrho cov lus qhia; nyob rau hauv lwm yam lus, lawv yog tom qab tsis tu ncua. Yog li ntawd, cov pob zeb uas tsis zoo sib xws, tab sis tam sim no tau sib cais los ntawm ib lub hav lossis lwm yam erosional feature, tuaj yeem suav tias yog thawj zaug txuas ntxiv.

Tsis tas li ntawd, pob zeb yuav pab ua pov thawj txoj cai ntawm kev txuas ntxiv mus li cas? Cov pob zeb cov khaubncaws sab nraud povtseg tau muab tso rau tom qab qhov kev tshwm sim tilting thiab yog rov pw tiaj tus. Cov Law of Lateral Continuity qhia tias tag nrho pob zeb txheej yog tom qab txuas ntxiv thiab tej zaum yuav tawg los yog hloov chaw tom qab cov xwm txheej. Qhov no ua tau tshwm sim thaum tus dej los yog kwj deg erodes ib feem ntawm lub pob zeb txheej.

Kuj paub yog, dab tsi yog lub hauv paus ntsiab lus ntawm thawj kab rov tav?

Cov Lub hauv paus ntsiab lus ntawm Original Horizontality tau thov los ntawm Danish geological pioneer Nicholas Steno (1638-1686). Qhov no txoj cai hais tias cov khaubncaws sab nraud povtseg ntawm sediment yog Ameslikas tso horizontally nyob rau hauv qhov kev txiav txim ntawm lub ntiajteb txawj nqus.

Lub hauv paus ntsiab lus ntawm kev suav nrog yog dab tsi?

Cov txoj cai ntawm kev suav nrog thiab Cheebtsam hais tias, nrog sedimentary pob zeb, yog tias suav nrog (los yog clasts) pom nyob rau hauv ib qho kev tsim, ces tus suav nrog yuav tsum yog laus tshaj qhov tsim uas muaj lawv.
