In this paper we reviewed thermodynamcis and the kinetics of gas hyrate decomposition via jamaluddin model in the seafloors and it’s correlation to sandy environments in this study it was shown that dissociation of hydrate started from the interface of sans and hydrate: thereafter , it grew to eht pore space. this suggests that the behavior of dissociation are closely related to the heat and mass transfer phenomena such as the thermal balance between the heat of dissociation and the rate of heat transfer into sediments and the mass balance of porous media flowin very fine pore space the rate of dissciation of gas hydrates can largely change depending on the environmental situation of porous media and heat or mass transfer.
