Tanezrouft 091 Meteorite – a Rare Mesosiderite da Algeria Tanezrouft 091 meteorite is a rare stony-meteorite ferroso of the mesosiderite type, discovered in 2020 in the Tanezrouft region near the town of Adrar in Algeria. The total known weight of the material is approximately 4,988 grams. The meteorite consists of several fragments, some of which were later cut and distributed to collectors and scientific institutions. There are very well preserved slices with complete edges and visible fusion crust, showing the typical mesosiderite structure – alternation of metal and silicate components. Classification and Origin da a mineralogical perspective, Tanezrouft 091 corresponds to mesosiderite A3, S-low, W-low, meaning a moderate degree of structural integrity and a low degree of weathering and shock alteration. Mesosiderites generally form through collisional processes, where metallic and silicate material is mixed – likely due to the impact of a metallic core into the silicate crust of a planetesimal body.
