Conference Paper: Evaluation Of Geothermal Resources In The Dien Bien Region (The Northwestern Part Of Vietnam)

Abstract
Geological, geochemical and geophysical surveys were performed in the Dien Bien to build up the hydrothermal model associated with the Dien Bien hot springs. The geomorphology of the surveyed area is dominated by the Dien Bien Depression, which is a graben whose axis is oriented N-S. Four major geological structural features have been considered in the area: 1- Dien Bien deep seated fault system, 2- the Nam Rom deep seated fault, 2- the NW-SE fault and 4- theNE-SW fault, crossing the above mentioned depression and Dien bien deep seated fault system, intersecting Dien Bien city centre. The integrated interpretation of the geological, geochemical and geophysical data, suggests a meteoric origin for Dien Bien thermal waters which infiltrate in the northwestern zone of Dien Bien Depression or further areas, percolate at great depth and ascend at the Dien Bien Depression, probably due to the intersection of the existing fault systems In fact, in the above mentioned zones, low resistivity values were measured, which are associated with the hydrothermal fluid circulation.
