Another interesting thing, I read on the landscape and perception site that the outer Bluestone ring is made up of dolerite and the other rock types present under the 'bluestone' umbrella, but the inner horseshoe is comprised solely of spotted dolerite.
All are dolerite 62 is unspotted
Ah! thanks.
Is there such thing as a lesser-spotted dolerite?

Just wondered.
