Granite Kit and its alteration (1 group)

The three samples of granite at different stages of weathering can be observed, compared, drawn, and classified during the lab session. These samples also allow for the observation and identification of minerals that make up the rock. All samples come from the granite massif of Flamanville (Cotentin, Manche). The kit consists of: - 1 sample of polished healthy granite with a natural surface and fracture on the edges (5 to 7 cm) - 1 sample of weathered granite (5 to 7 cm) - 1 bag of granitic sand
