Abstract

In the original language

In the Czech part of the Upper Silesian Coal Basin, highly mineralised mine waters and waters from draining coal dumps cause the distinct formation of incrustations close to watercourse areas. By using X-ray powder microdiffraction, incrustations emerging from the drains of hard coal heaps were identified as a carbonate system with the dominant mineral monohydrocalcite and subsidiary aragonite, calcite and gypsum. The newly formed minerals were studied by other techniques such as LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry), EPMA (Electron Probe Microanalysis) and Raman spectroscopy with the primary objective of detecting any trace elements entering the structure.
