  Remote sensing technique for capturing and exploration of mineral deposit sites in Gumushane metallogenic province, NE Turkey

  Vural, Alaaddin; Corumluoglu, Özsen; Asri, Ibrahim

  This study examines the determination and confirmation of mineral deposits in the Gumushane Province,Turkey. Rather than using classical techniques, Remote Sensing (RS) and Geographic Information System GIS technologies are applied for this purpose. Mineral alteration traces on the ground are characteristic indicators of ore below the surface. These traces can be determined using RS techniques. The Crosta technique is one of the most important RS image analysis methods used for the determination of mineral alterations. The technique has shown particular usefulness around mine areas, which are rich in ore deposits and show hydrothermal alterations. Therefore, four separate mine fields covering a total area of 718 km2 in the southern part of Gumushane, which is rich in iron oxides, hydroxides and hydrothermal alteration, were chosen. The Crosta technique was applied to the satellite image of each area to explore the regional alterations. The determined locations could be confirmed as alteration areas. Within these four regions, some other locations showing similar alteration patterns were also determined using the Crosta technique. These locations represent good candidates for mineral exploration.

  Contamination assessment of heavy metals associated with an alteration area: Demirören Gumushane, NE Turkey

  Vural, Alaaddin

  Soil samples collected from Demirören Alteration area, Gümüshane NE Turkey were analyzed for heavy metals by using Inductively Coupled Plasma-Atomic Emission Spectrometry and Inductively Coupled Plasma-Mass Spectrometry and the contamination level of heavy metals was assessed on the basis of Geoaccumulation Index, Enrichment Factor, Pollution Index and Integrated Pollution Index. The results indicated that, in comparison with background value of upper crust, soil samples in Demirören alteration area have elevated levels of metal concentrations as a whole. High Geoaccumulation Indexes and Enrichment Factors for molybdenum, lead, selenium, bismuth, cadmium and copper in alteration area indicated that there is a considerable amount of especially molybdenum, lead and copper pollution, which mainly originate from alteration in the area.
