More model informationHere you can see a lamprophyre dyke intruding granite. It has also split a pegmatitic phase in the granite. The dyke also has convolute margins and shows a partly rounded piece of the host granite that has fallen into the dyke magma - both consistent with a partly molten granite host at the time of dyke intrusion. Lens cap is ~62 mm in diameter.
A broader scale model of this outcrop can be found here.
