Rhyolite/Dolerite, whatever...... :]

Where dolerite is the sub-volcanic(i.e deposited underground) equivalent of a basalt, rhyolite is the volcanic to sub-volcanic equivalent of granite (compositionally speaking).
The rhyolite at Frog, although compositionally different to true dolerite, is 'texturally' very similar to the columnar dolerite seen in many parts of the world (e.g. Tasmania). The rhyolite at Mt Coree (ACT) is very different to Frog (no columnar jounting).

In any case rhyolite and dolerite are very different from dolomite.
