Ore controlORE CONTROL IS ATTRIBUTED TO METAMORPHISM INDUCED BY THE BUSHVELD IGNEOUS COMPLEX (NOW NO LONGER IN EXISTANCE IN THIS AREA). THE "ALGAL ORES", OCCURRING AS STRATIFORM BODIES IN THIS PORTION OF THE OVERALL DEPOSIT, EXIST ONLY IN THE UPPER PART OF THE DOLOMITE SERIES; AS REPLACEMENTS OF STRATOLITIC STRUCTURES.
Geology
StructureLOCAL STRUCTURES FOLLOW THE REGIONAL PATTERN PRECISELY. THE DOLOMITE, AND ITS CONTAINED FLUORSPAR, DISPLAYS LITTLE OR NO DIP LOCALLY. FAULTING AND FOLDING IS NON-EXISTENT., 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.
AlterationSURFACE AND NEAR-SURFACE ALTERATION OF THE DOLOMITE TO A MANGANIFEROUS SOIL-LIKE CLAY, RICH IN FLUORSPAR.
