ANALYTICAL AND EXPERIMENTAL-STUDY OF THE THERMAL REGIME OF SOUTH-CASPEAN SEDIMENTS

A change in heat flow of the lithosphere in the sedimentary rocks of o ceanic crust is considered in terms of conductive model for thermal co nductivity. The entire cycle of the investigation is described, includ ing the field works, experimental study of thermophysical properties o f nonconsolidated sedimentary rocks and theoretical interpretation of data. Results of complex studies are given in short: revealed features of temperature behavior of thermophysical properties of the above-men tioned rocks; experiment-based technique for reconstruction of thermal parameters of water-saturated rocks according to data of study of dry specimens. The main result of the work performed is the conclusion on possible essential effect of the processes occurring in the oceanic s edimentary unit (organics decomposition, gas- and oil formation, decay and formation of gas hydrates) on the value of surface heat flow.
