What is slate formed by?

Slate is formed from the metamorphism of shale or mudstone. This process involves intense heat and pressure which causes the shale to recrystallize into a fine-grained, foliated rock with excellent cleavage properties.

What are the changes caused by metamorphism of shale to slate?

With increases of heat and pressure deep underground on shale, chlorite and mica minerals form and line up along basal cleavages, imparting the new rock slate with "slatey" cleavage. Slately cleavage is a characteristic of rock that can be broken into thin sheets with smooth flat faces. Visible on these smooth flat faces is a somewhat noticeable sheen from light reflection. This occurs as the light is bounced off the aligned cleavage faces of the minerals contained in the slate.
