| This is followed by ophitic or poikilitic crystallization of pyroxene and ilmenite about scarce nuclei, produced at lower temperatures. |
|
| Pegmatite bodies associated with ophitic granite were identified, some up to 2 km long and 500 m wide. |
|
| It is a narrow fissure vein cutting an ophitic lava flow and is typical of many of the noncommercial mineralized veins in the general area of Keweenaw Point. |
|
| Bituminous mixtures have an AC 16 S grain-size distribution with ophitic aggregate and a void percentage that depends on the filler used. |
|
| These zones also control the location of minor bodies of rapakivi in southern Finland and an ophitic gabbro body in the Tallinn zone. |
|
| The mineralization was observed to be contained within a NW-trending shear zone that transects an ophitic gabbro intrusion along the southeast wall of the pit. |
|
| The flow is a coarse-grained, ophitic basalt containing heavily altered plagioclase and relatively unaltered clinopyroxene. |
|
| The geological formation where the magnetite mineralization is located in the various fields is a Triassic Keuper facies associated with ophitic sub volcanic rock. |
