| Amazing and fantastic forms of representatives of the mineral world are displayed in the exhibitions dedicated to crystals, mineral aggregates, and pseudomorphs. |
| These are actually pseudomorphs of sericite after cordierite and are found included in hornfels or slate as a product of contact metamorphism. |
| It pseudomorphs after sérandite and offers some of the most exceptional crystal specimens at Mont Saint-Hilaire in sizes up to 20cm. |
| Similar malachite masses weighing up to 3 tons as well as malachite pseudomorphs after cuprite crystals to 2 cm have been found in the mine. |
| They noted that good pseudomorphs of limonite after pyrite, both as cubes and as pyritohedra, are common, especially in bodies of massive pyrite. |
| In one isolated occurrence, aggregates of small cerussite crystals form pseudomorphs, less than 2 mm across, after an unknown mineral. |
