Al-rich relic material from the formation of the rapakivi granite melt is another source of assimilation.
That said, the stele, a piece of black granite, about 4 high and 2 across, mounted on a 2 high square base, was unveiled.
This disturbance might in part be related to fluid percolation associated with the shear zones traversing the granite.
The granite occupies the northern parts, whereas in the south the massif is composed of gabbro in the west and leucogabbro in the east.
In contrast, axial ratios of granite clasts in some instances actually decrease adjacent to the contact.
The rock fragments are mainly rhyolite, granite, and spherulite of rhyolite, with very small amounts of muscovite-quartz schist and hornfels exhibiting a granoblastic texture.
Therefore, some aspects of the chemical composition of granites likely reflect their source material.
Dolomitic clasts have shape ratios typically 10 to 15 times higher than granite clasts.
