5 Formation
5.1 Formation
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
