Economic information

Geologic structures

Type of structure Local
Structure description LOCAL STRUCTURES FOLLOW THE REGIONAL PATTERN PRECISELY. THE DOLOMITE, AND ITS CONTAINED FLUORSPAR, DISPLAYS LITTLE OR NO DIP LOCALLY. FAULTING AND FOLDING IS NON-EXISTENT.
Type of structure Regional
Structure description THE BEDS OF THIS AREA ARE GENERALLY FLAT OR DIP VERY GENTLY. EXCEPT FOR THE INTRODUCTION OF THE BUSHVELD IGNEOUS COMPLEX, ITS SUBSEQUENT EROSION, AND THE DEPOSITION AND DENUDATION OF MORE RECENT SEDIMENTS, LITTLE OR NO OTHER STRUCTURAL INFLUENCES ARE EVIDENT. FOLDING AND FAULTING, REGIONALLY, ARE OF MINOR IMPORTANCE ONLY.

Controls for ore emplacement

  • ORE CONTROL IS ATTRIBUTED TO METAMORPHISM INDUCED BY THE BUSHVELD IGNEOUS COMPLEX (NOW NO LONGER IN EXISTENCE IN THIS AREA). "BLOCK-SPAR" ORES, OCCURRING AS STRATIFORM BODIES IN THIS PORTION OF THE OVERALL DEPOSIT, EXIST IN DARK-COLORED DOLOMITE WITH LITTLE OR NO ALGAL STRUCTURE. A SYNSEDIMENTARY ORIGIN IS SUGGESTED, WITH SUBSEQUENT RECRYSTALLIZATION AND REMOBILIZATION
