This produces the ophitic structure (very common also in the dolerites).
Many of them are ophitic, especially those which contain olivine, but others are intersertal, like the intersertal dolerites.
Ophitic structure is commonest in olivine-dolerites, though the olivine takes no part in it.
- (of the texture of rocks such as dolerite) having small elongated unorientated feldspar crystals enclosed within pyroxene grains
