The Tirremi fluorite deposit, located in the Taourirt region (Eastern Morocco), morphologically constitutes a mainly carbonate dome of the Jurassic age, crossed by numerous dykes of lamprophyric rocks of Eocene age. The tectonic study coupled with the study of lineaments extracted from band 2 of the sentinel-2 image shows that the main directions, in terms of frequency and size, are NE-SW and E-W to ENE-WSW. The other directions, N-S and NNW-SSE, are satellite faults with respect to the potential faults; but they are economically important since they give rise to fluorite-rich veins. Similarly, analysis of fracturing (faults, tension cracks, dykes, etc.) allows us to identify the Palaeostresses of stress responsible for the structuring of the Tirremi region. These phases, classified in chronological order based on field observations, are perfectly compatible and correlatable with previous work done in the area.Downloads
