| Fayalite then solidifies around the grains, gluing the sand onto the surface of the casting. |
| Several pools of syenitic magma were separated from the main body of the melt, each eventually being emplaced as quartz syenite, fayalite granite, and riebeckite granite. |
| As seen in the granite, subhedral to anhedral grains of fayalite are fractured and show varying stages of alteration to hematite, antigorite, calcite, and magnetite. |
| Associated with the fayalite are quartz, amphibole, and magnetite. |
| These minerals occur with manganoan fayalite and manganoan magnetite in a single sample. |
