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. White Massive Fluorite Occurs In A Horizontal Contact Zone Between An Early Peripheral Granite And A Later Core Granite.
