2) and often retain the textures of magmatic rocks, - poikilophitic, intersertal, for globular lavas, - hyalopilitic (Petrov, 1999).
The spilitic basalts have plagioclase, clinopyroxene and minor opaque minerals (titaniferous minerals) that have intersertal texture.
They have porphyritic texture with plagioclase phenocrystals (up to 10 %) in a subophitic to intersertal groundmass.
In some areas, generally near contacts with the Baring Granite unit, quartz diorite has hiatal porphyritic texture with plagioclase phenocrysts 2 to 4 cm in length, set in a fine-grained intersertal to intergranular matrix of augite, plagioclase, and quartz.
Most of the basalts are porphyritic and textures range from very fine-grained to very coarse-grained, using these terms in the volcanic sense (Table 1), and include ophitic, subophitic, intergranular and intersertal varieties.
Groundmass textures are variably intergranular, intersertal, vitrophyric, and hyalopilitic.
