STATISTICAL ANALYSIS OF STREAM SEDIMENT SAMPLING IN VOLCANIC COMPLEX MITROVICE – SAMADREXHE FOR SELECTED ELEMENTS
Abstract
Kosovo has a varied geology that ranges in age from the Neo-Proterozoic to the Holocene. The geology is characterized by substantial structural features on a regional scale, including, normal faulting and thrusting. The area belongs to the External Vadar Zone (EVZ). The Volcanic complex Mitrovic\"e – Samadrexh\"e is dominated by Jurassic and Neogene volcanic rocks from several eruption centres, interlayered by metamorphic and sedimentary units. The survey area was determined in the adjacent area of the known Pb – Zn – Ag polymetallic occurrences of Stant\"erg, Magjer\"e and Gumnisht\"e with a certain potential for Au mineralisations. They sum up to around 327 km², with a maximum 15 km SWNE and 32 km NW–SE extension. The samples were analysed over a suite of 53 elements by ICP-MS measurements. The comparison of the maximum values, arithmetic mean and median values with the Clarke values (average of the Earth crust) shows that the survey area is specialized for such elements as Ag, As, Au, Cu, Hg, Pb, and Zn. Statistical distributions are presented through histograms. Intervals or bin limits are determined based on characteristics of values for each element in order to gained more clear distribution that present main anomalies. Correlation analysis included linear regression and linear correlation coefficient (r)..Linear correlation coefficient (r) is used us indicator for the strength of the relationship between the variables. Regression analysis is used to predict values of a dependent or response variable from the values of one or more independent or explanatory variables. The geochemical survey of the Mitrovic\"e – Samadrexh\"e Volcanic Complex area has detected a variety of geochemical anomalies. The geochemical survey has proven the high potential of the area for the detection of Au, Ag occurrences and the appearance of other metals like Pb, Zn, Hg as well.
