Ghana is located on the northern coast of the Gulf of Guinea in West Africa, where mineral resources are widely distributed. Through the detailed study of Ghanaian magnetite breccia, it is found that Ghanaian magnetite breccia is mainly distributed in magmatic rocks, and the breccia shapes are diverse, including round, sub-angular and angular, and the proportion of round to sub-angular and angular content reaches about one-half, which has obvious characteristics of fragmentation. Most of the metal minerals in the magnet breccia are wrapped with other minerals, and the secondary increase phenomenon can be seen on the edge of the breccia, and the individual breccia develops pores, because of the different iron content. The cement of magnet breccia is mainly fine-grained clastic material or clay minerals, with particle size less than 0.03mm. It is believed that the breccia in Ghana magnet breccia can be divided into two types, namely rock breccia and metal mineral breccia. The formation process of breccia is mainly divided into two stages, namely magma formation stage and magma solidification diagenesis stage. The analysis of mineralogy and diagenetic process of Ghana magnetite breccia is of great geological significance for understanding the magma fluid interaction and metallogenesis in this area.
