Associate Professor Shahen Khachatryan Speaks About Uranium and Thorium Mine Ores in Amulsar Gold-Bearing Quartzites: AEF

Armenian Environmental Front Volunteering Initiative

We bring to your attention the article by Shahen Khachatryan, PhD in Geological Sciences, Associate Professor on the availability of uranium and thorium in the territory of Amulsar Mount.

In 2007 an agreement was signed between the Governments of the Republic of Armenia and the Russian Federation on the joint search, exploration, extraction and processing of radioactive elements in the territory of the Republic of Armenia.

We have valuable information on the distribution of radioactive elements in RA, their genetic types, ore composition and types in the articles and monographs published by Dr. P. Aloyan and his son, H. Aloyan, who is the CEO of Lydian Armenia Company. (P.G. Aloyan, G.P. Aloyan2006, 2008; P.G. Aloyan 2007, 2009).

In 1952-54, the Gromov expedition carried out investigations in the upper reaches of Arpa and Vorotan Rivers of Vayots Dzor Region and outlined 255 km2 surface with high radioactivity which is known as the Jermuk crown. (P.G. Aloyan, G.P. Aloyan, 2008)

The crown of Jermuk covers the district of Jermuk town, the village of Zirak, the upper reaches of the Vorotan River, its left and partially uphill slopes up to the village of Ghorayk. On this surface, the anomalous fields of Amulsar, Zirak, and Jermuk have been identified on the basis of radiometric data (Sarukhanyan, 1955).

The most promising of these sites was Amulsar ore mine, located 4.5-5 km south-east of Kechut village, 5.0 - 5.5 km north-west of Amulsar peak. It covers about 3 hectares and is located at 2300-2500 hypsometric levels.

The studies have shown that the high background radiation is conditioned with the availability of uranium, thorium and radium. Uranium and thorium are in the form of their own minerals in the rocks. Chemical analysis of thorium in the groove and dot samples taken from the mountainous mine opening of Amulsar ore mine shows that the content of thorium varies between 0.001 - 0.082% and uranium 0.001 - 0.068%. Uranium content in single samples was determined to be 0.5% (Sarukhanyan, 1955).

For comparison, the average normal uranium content in the crust of the earth is 4 g/t, i.e. 0.0004% (Maghakyan, 1958). The average uranium content (0.025 - 0.03%) in Amulsar is about 60 times higher than normal, which means we are dealing with high uranium concentrations.
