Abstract

Thermoluminescence (TL) studies on the metasediments of Jabar, lying in the northwestern part of Purulia district of West Bengal, show natural thermoluminescence (NTL). These metasediments of Precambrian age, predominantly consist of marble, calc-silicates and granite gneiss. Each of the representative rock sample exhibits distinct TL glow-curves which can be successfully utilised in a number of geological applications. On the basis of natural as well as artificial thermoluminescence glow-curves, two distinct types of marble sequence have been identified.
