| Geochemically, the pyroxene nephelinite is highly enriched in LILE compared with the first one. |
| The most fundamental characteristic of tholeiites is the presence of a low-Ca pyroxene. |
| This sample contains large plagioclase and pyroxene crystals, some of which have a sponge-like texture. |
| The rock was of garnet gneiss, traversed by black dykes of pyroxene granulite. |
| This is followed by ophitic or poikilitic crystallization of pyroxene and ilmenite about scarce nuclei, produced at lower temperatures. |
| Therefore, pyroxene is the next mineral to start forming after olivine. |
