Dolerite boulder field- Kunanyi/Mt. Wellington, Hobart Tasmania
-Dolerite is a term for basaltic igneous rocks that have just started to grow crystals. It’s very common on Tasmania due to the island having rifted away from Australia – opening oceans tends to cause volcanic rocks to form, justlike at the mid-ocean ridges. These also break into columns and can fall apart after cooling. Note the foot for scale.
