Abstract
Journal of the Geological Society of Sri Lanka is a peer-reviewed and open access journal published by the Geological Society of Sri Lanka. It aims to publish the most topical and highest quality papers, summarizing the results of recent research across all sub-disciplines of the Earth Science. Papers are frequently interdisciplinary covering both pure and applied fields of Geology. Contributions often refer to local, regional and/or international studies and emphasize the development of the understanding of fundamental geological processes.
Highlights
Geothermal springs in Sri Lanka are situated in the Eastern and South-eastern side of the country, loosely associating the boundary between Highland Complex (HC) and Vijayan Complex (VC), extending northward as a ~350 km thermal spring line (Dissanayake and Jayasena, 1988) (Fig. 1)
Main scope of the present study is to identify the possible region of the heat source and the flow paths responsible for the origin of the Mahapelessa hot spring
Few granulite facies rocks were found in the VC side in Sooriyawewa and Andarawewa, which might be located in the mixed HC and VC zone, as interpreted by Kröner et al (2013)
Summary
Geothermal springs in Sri Lanka are situated in the Eastern and South-eastern side of the country, loosely associating the boundary between Highland Complex (HC) and Vijayan Complex (VC), extending northward as a ~350 km thermal spring line (Dissanayake and Jayasena, 1988) (Fig. 1). These thermal water springs have different flow rates and discharge temperatures, and are located in the low altitude regions (
