Comments on the geologic information

  • THE BELINGA IRON DEPOSIT IS BELIEVED TO HAVE FORMED AS THE RESULT OF SUPERGENE LEACHING OF SILICA FROM AN IRON- FORMATION THAT HAD BEEN STRUCTURALLY THICKENED BY ISOCLINAL FOLDING AND ENRICHED LOCALLY BY HYDROTHERMAL REPLACEMENT OF QUARTZ BY HEMATITE. THE FORTUITOUS COMBINATION OF META- SOMATIC REPLACEMENT AND STRUCTURAL THICKENING OF THE IRON- FORMATION OF BELINGA DURING PRECAMBRIAN DEFORMATION PREPARED A FAVOURABLE LOCALE FOR SURFICIAL LEACHING WHEN THE AREA WAS EXPOSED TO PROLONGED WEATHERING UNDER THE STABLE GEOLOGIC ENVIRONMENT OF THE CENTRAL AFRICAN SHIELD.
