TAILIEUCHUNG - Báo cáo " Application of Ground-Penetrating Radar (GPR) and Multi-electrode Resistivity Imaging (MRI) methods to discover old road foundations around Doan Mon vestige "

Archaeological Institute and Department of Culture and Information of Hanoi have made archaeological excavations inside Doan Mon vestige. As a result, at the depth of an yard covered by the brick, stone jetty of the Le Dynasty; at the depth of the road, covered by the lemon flower-colour brick, of the Tran Dynasty, below it is old road foundation of the Ly Dynasty have been found. With this information, we have investigated in order to get information for determining these old road foundations around Doan Mon vestige in the direction of old road foundations found inside. | VNU Journal of Science Earth Sciences 23 2007 126-135 Application of Ground-Penetrating Radar GPR and Multi-electrode Resistivity Imaging MRI methods to discover old road foundations around Doan Mon vestige Vu Duc Minh1 Nguyen Ba Duan2 1 College of Science VNU 2 Institute of Geophysics VAST Received 07 February 2007 Abstract. Archaeological Institute and Department of Culture and Information of Hanoi have made archaeological excavations inside Doan Mon vestige. As a result at the depth of an yard covered by the brick stone jetty of the Le Dynasty at the depth of the road covered by the lemon flower-colour brick of the Tran Dynasty below it is old road foundation of the Ly Dynasty have been found. With this information we have investigated in order to get information for determining these old road foundations around Doan Mon vestige in the direction of old road foundations found inside Doan Mon vestige. With the obtained results it can be seen that application of the combination of GroundPenetrating Radar GPR and Multi-electrode Resistivity Imaging MRI methods can fully satisfy the requirements of archaeologists in solving archaeological problems. Due to non-destructive feature fast investigating speed with less time and low cost the application of these methods can help archaeologists to quickly observe a whole picture of the area under investigation. The old foundation layer and the old road are shown rather clearly and continued to extend from Doan Mon Gate to Kinh Thien Temple. Beside we have discovered small objects scattered on different profiles. Keywords GPR MRI Profile Section Antennae. 1. Introduction The archaeologists always have difficulties in locating and mapping archaeological objects buried in the great depths and having no or very few signs on the ground surface. When facing that problem they often have to randomly carry excavation until they obtain more statistical features of the drilled samples the expected .
