The sector of Mugote repose on a kibarian socle olded from precambrian, surmonted by cenozoic sediments and inruded by magmatic rocks. Hydrothermalism followed these events.The geological formations of Mugote are in majority classed on metamorphic rocks’s family. The main lithologies are: quartzite, quartzo-shales, sandstonous shale, gneiss, greizen. Magmatism has allowed establishing pegmatites. From works on field and the macroscopic analysis of samples refered to relative dating principles, we deduct that locally the succession of formations is: gneiss, quartzite, shale, sandstonous shale. Theses formations are intruded by pegmatites and greizen.
