Whinstones
Whinstones are dark-colored, fine-grained igneous rocks that are commonly found in regions of volcanic activity. They are typically composed of minerals such as basalt, diabase, and dolerite, and are known for their hardness and durability. Whinstones often exhibit a distinctive columnar jointing pattern, resulting from the cooling and contraction of lava flows. These rocks are frequently used in construction and road building due to their strength and resistance to weathering.
