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 Exact Shape Of The Orebody Is Not Known As No Wall Rock Contacts Are Exposed. The Fluorite Is Massive, Granular, Green-To-White In Color And Stained Brown By Secondary Iron On Cleavage Planes.
