Problems of modelling of Zn-Pb ores of the Mississippi Valley-type in the sediments of the Younger Paleozoic

Stefan Kurek


Two hypothetical models of the are bodies in the carbonate sediments of the Younger Paleozoic have been presented. The first model. characteristic for the western part of the NE margin of the Upper Silesian Coal Basin, corresponds to the ore bodies related to the pre-Triassic paleorelief. In the second one - the ore bodies display a distinct vertical scatter with no relation 10 the pre-Triassic paleorelief. This model is characteristic for the eastern part of the area discussed. Differentiation in the models can result from the different stages of the karst system development. The karst systems. being the mineralization traps, determine the primary form of the are bodies.
