The formations crossed by the forage belong to the Bushimay System. They are essentially made up from top to bottom of soft formations (loose) including Sands and Sandstones subject to frequent landslides and which require appropriate protection methods and hard formations including limestone with hard sub-horizontal layers. Two essential parameters make it possible to interpret the ground crossed in the forage: the nature of the cuttings and the speed of penetration of the forage tool. The nature of the cuttings relates to the description of the different geological formations.

Rocks in the Earth’s crust can be characterized by measurable physical properties such as magnetic susceptibility, density, electrical resistivity. Geophysical methods are appropriate for measuring the contrast of these properties inside the earth. This contrast represents, among other things, a variation in the structural. The development of new geophysical data acquisition tools and techniques makes it possible to considerably increase the quality/quantity of data and, on the other hand, to reduce operating costs and implementation time. These data, beyond their quality, however require adequate processing to be usable in geological interpretation. The geological map depicts a window into the internal structure of the earth. It is the first tool used in the exploration of natural resources. Since the majority of the earth’s surface is covered by sediments and vegetation, it is important to develop other technologies that can map geology through this cover. We processed airborne magnetic data to interpret the geology of the study area. The aim of this research is to process the airborne magnetic data on Kabimba to identify anomalies, then confirm the lithological cause of each by core drilling. This determines the lithostratigraphic at the points of the geophysical anomalies. The drilling declines the true underground geology through the information provided by the cores which reflect the geological formations crossed. Two kimberlite occurrences have been highlighted in this site. They have a pipe-like structure and contain green to red kimberlite under a carbonate casing topped by Cretacic sandstone and Kalahari sand.
