Cov pob zeb mos yog ib pawg ntawm cov pob zeb uas ua los ntawm lawv cov kev ntxhib los mos thiab yooj yim ntawm kev ua haujlwm; lawv tau nthuav dav thoob plaws ntiaj teb. Piv nrog rau cov pob zeb nyuaj xws li granite thiab basalt, pob zeb mos muaj cov qauv xoob, porosity dua, thiab qis dua, ua rau lawv yooj yim dua rau kev txiav thiab txiav. Cov piv txwv ntawm cov pob zeb mos muaj xws li limestone, sandstone, shale, thiab talc, txhua qhov txawv los ntawm nws cov yam ntxwv ntawm kev pom: limestone feem ntau tshwm hauv lub teeb lossis greyish -dawb hues; sandstone nta zoo, granular zoo nkauj; shale nthuav tawm cov txheej txheem sib txawv; thaum talc xav tias du thiab mos rau qhov kov. Vim lawv cov kev ntxhib los mos, cov pob zeb no kuj muaj kev cuam tshuam ntau dua rau kev tawg thiab tawg thaum lub caij huab cua, qhov tseem ceeb uas cuam tshuam rau kev tshawb fawb geological thiab av tsim.
Hauv kev siv tswv yim, cov pob zeb mos yog siv dav rau lawv txoj haujlwm ua haujlwm thiab kev zoo nkauj. Hauv thaj chaw ntawm architecture thiab duab puab, limestone thiab sandstone yog nquag ua haujlwm los tsim cov mlom, tombstones, lossis cov khoom zoo nkauj rau cov tsev keeb kwm; Zoo sib xws, hauv kev tsim toj roob hauv pes, pob zeb mos feem ntau yog siv rau paving lossis ua cov suab paj nruag zoo nkauj hauv vaj. Ib yam li ntawd, ntau yam kev lag luam siv cov khoom siv pob zeb mos nyoos- xws li hmoov talc thiab limestone- hauv kev tsim cov khoom siv tshuaj, cement, thiab ceramics. Txawm hais tias cov pob zeb mos yuav tsis muaj qhov ua tau zoo ntawm lawv cov khoom sib zog, lawv cov kev ntxhib los mos thiab kev yooj yim ntawm kev ua kom ntseeg tau tias lawv tseem ua lub luag haujlwm tseem ceeb hauv lub neej niaj hnub thiab kev tsim khoom lag luam.
