    Abstract

    The gold-polymetallic deposit of Shahumyan is located in Syunick Region of the Republic of Armenia. It is displayed by a number of veins of latitude extent with sharp incidence northwards and southwards and stretch from 100 up to 500 m. The investigation of the deposit has been realized on horizons of 600, 700, 780, 820 and 860 m by means of underground mountain drillings and pit-holes. Sampling has been implemented, using both furrow and core procedures at 4 m radius. The analysis of the network density of sampling has been accomplished on basic formulas of statistics. After analyzing the results obtained it was indicated that possible expand of sampling radius is up to 12 m, providing the principle on accurate economic assessment of the deposit.

    Abstract

    We have revealed more than 200 accumulations of slag, foundries and the ancient exploitation excavations. Our investigations and the analysis of literature data bring us to some conclusions. Discovery of slags, ore debris and root way outs of magnetite sandstones like Haghartsin deposit of iron in the basins of the rivers Martziget (Alaverdi Region), Getik (Idjevan Region), the slope of the mountain Maylekh, on the Semyonov crossing, broadens the perspectives of revealing new big deposits of magnetite sandstones. As the requirements were on a small scale, the quantity of stocks, for the metallurgy of the ancient world, did not play an important role. The necessary conditions were deposition of ore bodies near surface, rich content of the metal, location of the deposit in the places approachable for a man, enough quantity of wood. The distance of slag accumulations from exploitations doesn't exceed 1-2 km, hence there is an opportunity to use slag as exploring sign. We are sure that there is a connection between "Lightning-Sword" from Armenian epos "David of Sasun" and the secret of getting iron by the direct renewal from magnetite ore.

    Abstract

    In the article the choice of method and the technique of complex geophysical investigations of the "Hankayin Djur" landslide is discussed with the purpose of investigation of engineering-geological composition and dynamics of landslide body. The suggested complex of geophysical methods will allow to decide setting elements of the same type landslide body. Suggested methods follow the dynamics of the landslide.
