Three samples of silicate minerals sold to us as being jadeite have been investigated concerning their TL properties and also EPR spectrum of one of them denominated here as JQ1. XRF has shown that one of them is an alkaline feldspar and two other, varieties of quartz; one was called JQ1 and the second one JQ2. JQ1 absorption spectrum is characterized by absorption bands at 410 and 600 nm, responsible for green colour. JQ1's 260 °C and 330 °C TL peaks respond to very high dose, therefore it can be used as high dose dosimeter. The EPR spectrum presented g =4.5 Fe3+ signal and several non-identified signals in the 3460 to 3500 G interval. The typical E'1centre in quartz was not observed here. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
