Foreign geologists have used GPR in many fields of outcrop geological studies such as 3D reservoir molding, sedimentary facies analysis, high-resolution sequence stratigraphy, 3D fracture imaging, shallow-fault finding, paleokarst study and so on. The Ordovician carbonate outcrops of Bachu Dawuzitage hills in the Tarim Basin are well developed and present abundant geological phenomena including bioherm-beach assemblages, intrusion of igneous rocks, karst features and so on. Ground penetrating radar experimental survey with frequency of 32-500 MHz has been conducted in this area. The results indicated that the penetrating depth can be up to 20 m with the maximum resolution of decimeter. Many geological features, such as reefs, channels in the reef, small-scale faults and karst caves, have typical responses in the high-resolution GPR profiles and can be corresponded well with outcrops. This provides a new associate approach for the outcrop study of carbonate rocks.Read More
