Radioactivity and heat sources in the Central depression of Chiapas state, Mexico

Abstract

Contents of Uranium, Thorium and Potassium were measured - Ꝩ-ray spectrometry in some rocks as well as thermal waters from the central depression of the State of Chiapas. The results of these measurements show what the samples do not have high radioactive contents, possibly implying that radioactive elements are not responsible for the presence of hot-springs in the area. Further, heat-balance calculations of a geological model representing an extrusive igneous body emplaced in the above –mentioned central depression show that such bodies might be the possible heat-sources for the thermal waters in the sea.
