Description Culm conglomerates in the quarry in Luleč are intersected by tectonic fault. Hydrothermal mineralization is formed on their planes. It is typ Alpine Paragenesis. The dominant compressed mode caused formation of reverse faults and overlying landscape began to shift in the direction of East. Quartz-calcite-laumontite mineralization were developed on the planes of the faults from low temperature hydrothermal solutions enriched with calcium. Laumontite is concentrated specially on granulite boulders. The form of mineralization demonstrates its synkimenatic formation which occurred at low pressure and low temperature during regional metamorphism at a depth of 3-4,8 km below the surface.
