Optical Properties and Natural Radioactivity Levels of Turkish Natural Glass Obsidian

Year 2019, Volume: 6 , 138 - 141, 25.07.2019

Abstract

Obsidian
is a naturally occurring volcanic glass formed as an igneous rock. It is a kind
of alumino-silicate glass containing iron impurities and some tiny particles
(particle-dispersed glasses). It can be found in black, gray, brown, blue, and
green colors in nature. In recent work, the obsidian specimens in black and
brown colors were collected from Sarıkamış which is a small town in Kars
province located at the north-east part of Turkey. The obtained specimens were
then cut and polished to obtain two parallel surfaces to perform optical
measurements. The optical absorption spectra of the samples were collected
under ambient environment. The natural radioactivity levels of the specimens
were also measured using a gamma spectrometer whıch uses a NaI(Tl)
scintillation detector for the determination of the radioactivity.
