Can you provide a source for dust on Mars being jagged? If I understand correctly, this is true on the moon where erosive processes weren't present historically. But on Mars, we have ample evidence that they were for millions of years. Also, Mars dust particles are extremely small, with the majority of airborne dust in the 1-10 micron range (https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.hou.usra.edu/meetings/ninthmars2019/pdf/6298.pdf&ved=2ahUKEwiJidmt8NPzAhWrlmoFHcg5BZsQFnoECA0QAQ&usg=AOvVaw1kJ9-x4DY6840vMjsHNu68 https://www.google.com/url?sa=t&source=web&rct=j&url=https:/...) although it sounds like sand may be larger (https://www.researchgate.net/publication/236899547_The_particle_size_of_Martian_aeolian_dunes https://www.researchgate.net/publication/236899547_The_parti...), but I haven't seen any research on the shape.
