Lub physicochemical thaj chaw ntawm Taihu pob zeb yog intimately txuas rau lawv cov txheej txheem tsim thiab tshuaj muaj pes tsawg leeg. Cov pob zeb feem ntau yog limestone-tshwj xeeb yog calcium carbonate- cov pob zeb no muaj kev cuam tshuam loj heev rau kev tawg los ntawm cov dej uas muaj carbon dioxide. Nyob rau lub sijhawm ntawm geological epochs loj, los ntawm kev sib xyaw ua ke ntawm kev cuam tshuam ntawm nthwv dej thiab tshuaj lom neeg tawg, lawv maj mam hloov mus rau hauv lawv cov ntawv tshwj xeeb-tus cwj pwm los ntawm slenderness, convolutions, perforations, thiab translucence, as well as sinuous contours thiab rounded surfaces-yog li ntawd lawv cov yam ntxwv zoo.
Hauv paus, lub hauv paus chiv keeb ntawm Taihu pob zeb muaj qhov sib txawv: txhua qhov chaw limestone deposits muaj nyob - thiab qhov twg cov struts tau undergone ntev aqueous erosion (xws li erosive thiab corrosive actions ntawm pas dej, dej dej, los yog hauv av) {{1}Taihu possibilities ntawm lub pob zeb. Qhov no yog vim limestone cov ntsiab lus tseem ceeb, calcium carbonate, nkag mus rau tshuaj lom neeg cov tshuaj tiv thaiv nrog dej thiab carbon dioxide, ua rau nws tawg; Thaum lub sij hawm geological uas nws kim heev, cov txheej txheem no yields pob zeb specimens muaj cov cim morphologies thiab txhais cov yam ntxwv ntawm Taihu pob zeb. Cov yam ntxwv zoo li no suav nrog kev faib tawm ntawm Taihu pob zeb; Tseeb tiag, txhua qhov chaw uas txaus siab rau cov lus hais saum toj no geological prerequisites muaj peev xwm los ua ib qho chaw rau zus tau tej cov Taihu pob zeb.
