Kev tsim cov dej ntxhia ntuj pib nrog nag lossis daus (los nag thiab daus) nkag mus rau hauv av. Cov dej no ces lim los ntawm cov pob zeb xws li sandstone, conglomerate, thiab limestone nrog zoo-tsim fissures, undergoing qeeb tshuaj tiv thaiv nyob rau hauv av uas yuav kav los ntawm kaum xyoo mus rau pua pua los yog kaum txhiab xyoo.
Mineralization feem ntau suav nrog kev sib cais, hloov pauv ntawm adsorbed cations, redox tshuaj tiv thaiv, evaporation thiab concentration, thiab sib tov.
Cov dej ntws los ntawm cov pob zeb tshwj xeeb, xws li limestone thiab dolomite, dissolves cov zaub mov kom tsim cov dej ntxhia nplua nuj hauv calcium thiab magnesium. Volcanic pob zeb, xws li granite, yog nplua nuj nyob rau hauv metasilicate acid. Impermeable pob zeb txheej saum lub aquifer, xws li shale thiab claystone, muab kev tiv thaiv.
Cov dej ntxhia yog khaws cia rau hauv cov dej hauv av thiab ib txwm tshwm sim los ntawm thaj chaw txhaum cai los tsim cov dej ntws hauv artesian, los yog muab rho tawm los ntawm cov khoom siv dag zog. Noj Jinjiang Ntuj Mineral Dej hauv Manjiang Lub Zos, Fusong County, Jilin Xeev ua piv txwv, nws nyob rau sab qaum teb sab hnub poob -trending compressional- shear txhaum. Thaum lub sij hawm ntws hauv av raws qhov txhaum, nws dissolves thiab enriches soluble mineral Cheebtsam xws li SiO₂ nyob rau hauv ib ncig ntawm lub pob zeb, tsim metasilixic acid hom ntxhia dej.
