A Mechanism to Explain the Exponential Model for Heat Production (original) (raw)

Abstract

Evidence for chemical interaction between plutons and meteoric ground water and analyses of the micro-scale and mega-scale distribution of uranium and thorium suggests that thermal convection in batholith complexes mobilizes uranium and may partially explain the exponential model for the vertical distribution of crustal heat production. Investigations of the distribution of uranium, thorium, and potassium within and around eight shallow plutons show evidence for mobilization and redistribution of uranium that was not bound in resistate-refractory minerals. Induced fission track radiography of thin sections was used to reveal the mineral associations of uranium within the rocks. Shallow plutons showing evidence of significant chemical interaction with meteoric groundwater (delta 18O) contain significant amounts of uranium in secondary hydrous minerals and secondary oxides. Plutons from deeper levels in the crust that show no evidence of interaction with meteoric ground water show ura...
