Title

STREAM-SEDIMENT AND HEAVY MINERAL STUDIES IN JALDEHBAKHAN AREA, EAST-AZARBAIDJAN

Pages

  315-325

Abstract

JALDEHBAKHAN area, located at southeast of East-Azarbaidjan, forms a part of the Tarom-Gaharadagh metalogenic province. The regional geochemical explorations led to the discovery of anomalous areas for variety of elements. The Control on GEOCHEMICAL ANOMALIES was implemented by studies of HEAVY MINERALS of STREAM SEDIMENTS and mineralized samples. The most important identified HEAVY MINERALS includes magnetite, hematite, limonite, martite, micaceous hematite, pyrite, oxidized pyrite, galena, native copper, gold, malachite, cuprite, zircon, apatite, rutile, ilmenite, sphene, pyroxene, amphibole, garnet, and epidote. The identified metallic HEAVY MINERALS are intimately associated with veinlet and epithermal mineralization. Analysis of some collected litho-geochemical samples from zone of anomalies show notable grade for elements such as Au, Ag, As, Ba, Bi, Ce, Co, Cu, Mo, Ni, Sb, V, and Zn. Combination of obtained data from chemical analyses, heavy mineral studies, petrographic examinations of mineralized samples, and field relations led to identification of zone of anomalies corresponding with main valley in the study area. Superposition of final anomaly map with fault density map of JALDEHBAKHAN area indicates that faults played a crucial role in creation of these anomalies. The overall obtained results from geochemical considerations show that the identified anomalies principally belong to elements such as Au, Ag, Ba, Co, Cu, Sb, and Zn that can be used as important tracer for exploration of epithermal gold and silver as well as polymetallic Au-Ag-Cu-Pb-Zn deposits.
