Vural, Alaaddin; Aydal, Doğan
Objective of this study is to use soil geochemistry surveys using statistical methods for the exploration of possibly gold mineralization related to Alakeçi listvenite area (Bayramiç, Çanakkale, Turkey). In the scope of soil geochemistry, about 350 soil samples were analyzed and evaluated for nine elements including gold. Element concentrations for Cu, Pb, Zn, As, Sb, Mo, Ni, Co and Au (all element except Au in ppm, Au in ppb) were 10-265, 10-90, 15-545, 5-800, 2-60, 4-8, 10-6300, 15-1255 and 40-300 respectively. The gold concentrations were comparatively detected in low value than important ore deposit and exhibited no correlation with other elements (except Mo). However, positive correlation was observed between Cu and Zn; Sb and As; Mo with As and Sb; Au and Mo; Ni and Co. In literature, Cu, Zn, As, Sb and Mo were widely used as pathfinder elements for exploration of gold mineralization. So, these elements were accepted as pathfinders in this study and their distribution maps were prepared. The element distribution maps for pathfinder elements and gold displayed remarkable zoning in the central to southeast site of the area connected with tectonic lines and lithological borders. So, in conclusion, this part in the area needs to be investigated in detailed with geophysics and drilling methods for blind gold mineralization.

İncele - MakaleYayıncıda açık erişim2019Scopus SJRQ4Evaluation of soil geochemistry data of Canca Area (Gümüşhane, Turkey) by means of Inverse Distance Weighting (IDW) and Kriging methods-preliminary findings
Vural, Alaaddin
The purpose of this study is to assess soil geochemical data of the Canca alteration area (Gümüşhane-Turkey) using statistical methods and investigate potential gold mineralizations of the area. With this purpose, 288 soil samples were collected and analyzed for gold and associated pathfinder elements. The concentrations ranged (Au and Hg: in μg/kg, others in mg/kg) between 0,68-19,20; 0,02-28,97; 2-314; 7-857; 2,1-394; 4-199,5; 0,59-49,29; 5-89; 0,04-37; 0,52-16,30; 1,25-91,9 for Au, Ag, Cu, Pb, Zn, As, Sb, Bi, Mo, Sn and Hg respectively. According to Sperman’s rho correlation coefficients, although not very strong, correlation was observed between Cu and Au; Zn and Cu; Sb and Pb and As; Mo and Pb and As and Sb; Sn and As; Sb and Mo. The threshold values of the elements were obtained by median+2 the median absolute deviation. The prediction maps of the elements were formed by using the Inverse Distance Weighting and Kriging methods. According to prediction maps; especially in the western part of the study area and also related to tectonic lines, elemental enrichments, (gold and silver) were determined. Therefore, it is suggested to give importance to the west of the area in exploration drilling, geophysics, etc. Since the element prediction maps produced by the Inverse Distance Weighting method has higher resolution in anomaly contrast, it is suggested that maps produced with this method can preferably be used to give an idea at first sight in soil geochemistry studies.

İncele - MakaleYalnız künye2012Scopus SJRQ1Soil geochemical prospection for gold deposit in the Arzular area (NE Turkey)
Yaylali-Abanuz, Gülten; Tüysüz, Necati; Akaryali, Enver
The Arzular gold mineralization is located at the southern part of the Black Sea Tectonic Unit in northern Turkey. This belt hosts several high-potential epithermal gold deposits and it is highly probable that there are a number of undiscovered occurrences in the region. The presence of intensely altered areas, suitable structural elements and acidic intrusions indicates that the region has an important potential for epithermal gold. Soil geochemistry surveys are widely used for the exploration of buried mineral deposits. In this work the applicability of soil geochemistry surveys for exploration of buried mineral deposits was tested using various statistical methods. In this respect, concentrations of 16 elements have been assayed in about 50 soil samples collected from the Arzular area. Soil samples were taken from the B horizon. The data revealed elevated concentrations for gold (0.20-259.2 μg/kg), silver (23-26,972 μg/kg), arsenic (1.7-301.8. mg/kg), copper (54.09-170.7. mg/kg), zinc (5.1-261.3. mg/kg) and lead (2.6-385.45. mg/kg). Gold is significantly correlated with elements such as Sb, Cd, Pb, Ag, As, Cu and Mo. Relatively high anomaly contrasts between Au, As, Ag and Sb and their coinciding anomalies along an E-W trending fault at the eastern part of the field might indicate that As, Ag and Sb could be used as a pathfinder element for exploration of gold deposits. Factor analysis was applied to elements in soil samples and then distribution diagrams were prepared using the factor scores obtained. In a distribution diagram for mineralization-associated factor score, two anomaly fields along the E-W trending fracture line and one anomaly field at the eastern part were distinguished. The largest anomaly in an ellipsoidal shape with long axis of 350. m was obtained from the southeast part of the area. Anomaly patterns show that factor scores might yield suitable and net results for the exploration. NE-SW trending fracture system is not related to mineralization and is younger than E-W trending fracture line. However, the E-W trending fault system controls the mineralization; therefore, the eastern extent of this fault zone needs to be investigated.
