Tremolite in nature can be in prismatic or fibrous (asbestos). The excavation of rocks containing tremolite during a tunneling operation may be simulated through milling, and this could be the origin of fibrous artefacts. The analytical procedure to determine the presence of asbestos in a rock sample requires its reduction in powder. The comminution effects could be a product of fibers from prismatic mineral,s while the results of this research show that the opposite can happen, as was the case with one sample, which initially appeared fibrous and whose fibrousness, after the grinding process, was reduced because the production of prismatic elements took over.
