It may also form as a result of contact. Web marble is a rock resulting from metamorphism of sedimentary carbonate rocks, most commonly limestone or dolomite. The iron oxide minerals contain traces of radioactive uranium and thorium, and these decay by expelling helium. Web the moqui marbles' precise ages come from a radioactive clock. The transformation of limestone into marble usually occurs at convergent plate boundaries where large areas of earth's crust are exposed to the heat and pressure of regional metamorphism. Web how does marble form? Web form of it when limestone buried deep in the older layers of earth’s crust is subjected to heat and pressure from thick layers of overlying sediments. Metamorphism causes variable recrystallization of the original carbonate.
