Integration of Remote Sensing and Geological Mapping for Economic Mineralization Mapping in Mwitika-Makongo Area, Kitui Country
Author(s): Githenya LK*, Mathu EM, Kariuki PC and Waita J
This study integrates geology with remote sensing techniques to establish geological structures and their associated economic mineralization in the rocks of Mwitika-Makongo area. The objective of this study was to map hydrothermally altered zones from Landsat 8/OLI of the study area and validate the results with geological mapping. The remote sensing methods included; band combinations, band ratios and lineament extraction. Geological methods consisted of, field mapping and geochemical analysis. The integrated techniques resulted in lithological discrimination of hydrothermally altered zones. Geological field mapping and geochemical investigations led to the interpretation of some iron mineralization in hydrothermally altered zones, especially around Kalima Kathei. It also led to the conclusion that lineaments control drainage patterns in the area. Chemical analysis using X-Ray fluore.. View more»
