| About the name |
Named in 1805 by Robert Jameson in honor of Jacques-Louis, Comte de Bournon [21 January 1751 - 24 August 1825], crystallographer and mineralogist. Count de Bournon left France after the French Revolution to England and did not return to France until the Bourbon Restoration in 1814. Count de Bournon was an active mineralogist and researched the composition of meteorites (as early as 1802), but his research in mineralogical classification is his best-known contribution and he authored several detailed mineral collection catalogs featuring his classifications. Count de Bournon was one of the founders of the Geological Society in 1807. Count de Bournon named |
| Streak | Steel-gray |
| Crystal System | Orthorhombic |
| Cleavage Type | Imperfect/Fair |
| Fracture type | Irregular/Uneven,Sub-Conchoidal |
| Morphology | Crystals usually short prismatic to tabular [001]. Crystals often form sub-parallel aggregates. Faces {hk0} striated [001], {h01} striated [010], {100} lustrous and striated [010], {010} usually smooth and lustrous. |
| Twinning | On {110} very common often repeated, forming cruciform or wheel-like aggregates ("cogwheels"). Twin gliding: x1 {110}, δ2 [110]. Usually exhibits polysynthetic twinning on {110}, in part due to deformation. |
