MHa | MHa1 | The rock is loose, friable and soft, with a yellowish clay-like colour. In this horizon, granules of various shapes (rounded or elongated) of decimetric to centimetric size can be observed, all mixed in a smooth, very fine clay matrix that is a little sticky to the touch. When the granule is broken with a hammer, a red kaolin coloration can be seen inside the granule, which contains fine quartz crystals that can be seen by their characteristic brilliance, and a diffuse stratification in the form of a bank stakes out the interior of the granule. |
