Abstract
The properties of Tibetan bright spots have been studied in this work with seismic attribute analysis. Tibetan bright spots are band of reflections along 150 km of the northern Yadong-Gulu rift in southern Tibet, which are made by INDEPTH project. Seismic attributes analyses are the separate displays of seismic time amplitude map. Attribute computation tools are developed in this work using complex trace analysis and have shown justification with example. Using the developed tools, frequency attributes of the INDEPTH seismic data have been produced and it has studied the properties of Tibetan bright spots. Analysis suggests the presence of free water below the analyzed seismic profiles at a depth of about 15 km along with the big low S-wave velocity layer starting from 15 km depth and continuing up to different depths from 45 km to 94 km.
