THE DIVERSITY OF VOLUMETRIC DENSITY IN SELECTED LITHOLOGICAL UNITS IN THE CU-AG DEPOSIT IN THE LUBIN-GLOGOW COPPER DISTRICT

Martyna Paszek

Abstract

This paper presents analyzes of volumetric density based on the results of experimental sampling at one of the Cu-Ag LGOM deposits. These analyzes were carried out in order to assess a value of this parameter in chosen 3 of 9 individual lithological units (streaky dolomite, dolomitic shale and carbonate sandstone).The selection of individual lithological units was based on the number of samples taken and examined in particular lithology. An attempt to determine the structure of variability of volumetric density was undertaken by using statistical and geostatistical methods. As part of the statistical analysis, basic parameters were calculated and also the areal homogeneity of volumetric density was examined by using multiple comparison (Games-Howell) test. Geostatistical analysis was based on relative semivariograms. For the statistical analysis, the research area was divided into six smaller parts. The shape of areas was determined by the configuration of sampling points, where the main determinant was the distance between the samples. The statistical analysis of volumetric density showed very small variability within the studied lithology unit for those areas and for individual subareas. There were no significant differences of empirical distributions from the theoretical normal distribution, except for one area for streaky dolomite and carbonate sandstone. The multiple comparison (Games-Howell) test revealed homogeneity of the distribution of the studied parameter within the carbonate sandstone in all areas. For the streaky dolomite three homogeneous groups were determined, and four in case of dolomitic shale.
