Morphology and pyroelectricity of tourmaline from Central Transbaikalia, Russia

Fifteen transparent prismatic tourmaline crystals of elbaite composition, with terminal pyramidal faces and basal pedion were measured on a two-circle goniometer. All samples studied are collected from two localities of gem-bearing miarolitic pegmatites in Central Transbaikalia, Russia – the Vodorazdel’naya mine and the Malkhan deposit. Their geology and mineralogy are described in detail by Zagorsky & Peretyazhko 1992 ; 2008. It was not clear from these morphological measurements weather the positive or negative end of crystallographic axis c is morphologically terminated. In order of determining true crystallographic and morphological orientation of tourmaline crystals, the pyroelectric effect of tourmaline was measured. Crystals were cooled to a temperature below 0 °C (approximately -10 °C) and afterwards heated to the room temperature. Relative electrical charge was measured with a digital milivoltmeter.
