Gabonese laterite is an important mineral resource, mainly distributed in the Gabonese region of Africa. Llaterite is a type of soil rich in iron and aluminum that is commonly formed in tropical and subtropical regions. Gabonese laterite is mainly composed of iron oxides and aluminum oxides and is rich in minerals such as hematite and bauxite. Due to the large amount of iron oxides, Gabonese laterites are usually red or brownish red. The laterite is formed by long-term weathering and leaching under tropical climatic conditions. The parent rock on the surface gradually decomposes in an alternating wet and dry environment, forming a soil layer rich in iron and aluminum.

Ochre is a collection of oolitic, bean shaped, and kidney shaped aggregates, often in irregular flat blocks. Ochre is an oxide mineral belonging to the corundum group hematite, mainly containing iron oxide (Fe2O3). It is a collection of oolitic, bean shaped, and kidney shaped aggregates, often in irregular flat blocks. Dark brownish red or gray black, with cherry red or reddish brown stripes, some with metallic luster. There are many circular protrusions on one side, commonly known as "nail heads"; There are dimples of the same size on the other side corresponding to the protrusion. Weight, hard texture, and a layered cross-section after crushing. The air is faint and the taste is light.
