The Study of Geological Constituents of Mid-Atlantic Oceanic Crust with the Application of Attributes in Seismic Profiles

The geologic constituents of the mid Atlantic seismic profiles have been studied with attributes ananysis to make a bridge in between geology and seismic. Attributes computation is justified for one test signal. Later the amplitude and frequency attributes have been estimated the mid Atlantic region seismic profiles. The image made in this work is found better than that of the raw seismic data. Amplitude attributes indicated reasonable stratified earth of the crust. The reflecting beds are well presented in the analyzed sections. The boundaries are characterized on the basis of basic wave propagation, as it is observed that the signal strength from the nearest reflecting bed is higher than that of distant bed. Estimated frequency attributes of the profiles are indicated the evidences that the oceanic crust are probably gabbros with little mixture of peridotite. The constituents are estimated on the basis of frequency distribution of each trace of the whole profiles. Analysis has suggested that gabbro and peridotite are the main geological constituents mixing up with different degrees with depths of the study area.
