The Polish Cu-Ag deposits on the Fore-Sudetic Monocline are characterized by the occurrence of sedimentary structures called the elevations of the Weissligend top. These are elongated forms in the shape of sandy shafts whose occurrence affects the change in the value of deposit parameters (including reduction of the shale series's thickness). In the Lubin deposit, these elevations are the least well-known among all such structures in the entire Lubin-Glogow Copper District (LGCD). The basic material of the study w...

The Cu-Ag Lubin deposit belongs to the Lubin-Glogow Copper District (LGCD), which is located in south-western Poland. Copper mineralization occurs in three main lithological units: sandstones, shales and carbonates. A characteristic feature of these deposits is the occurrence of elevation and depression of the Weissligend top, which are convex structures in the form of sandy swells that are probably relics of eolian dunes from the Rotliegend period. These zones usually have a significant impact on the quality para...

The subject of the study was to characterize three deposit parameters of Pacific polymetallic nodules (the content and the abundance of nickel and the nodule abundance) using classical statistical methods. The input data points come from 448 sampling points of a bed area of about 48,000 km2 in the Clarion-Clipperton fracture zone (approx. 1,000 km west of the coast of Mexico). The sample points formed a pseudoregular grid with an average distance between them of about 10 km. On the basis of these, the basic statis...
