StructureInward-Dipping Cone-Like Structure; Folding And Faulting (Including Low-Angle Thrusting) Exists, But Of Minor Importance. Erosion, Peneplanation And Build-Up Of Younger Sediments Are Basic Criteria Regionally., Locally, Faults And Folds Are Of Minor Importance Only. The Occurence Dips Uniformly 35-40 Degrees To The West With Purple Fluorite Occuring As Replacement Layers (Veins) Subparallel To The Relict Bedding Of Leptite.
