Roofing slates are roofing tiles made out of slate. The rock is split into thin sheets which are cut to the requires size before shipment. This contrasts to slabs which are milled to produce larger structural components. [1] They are the primary product of the slate industry.
Slate is an example of a foliated metamorphic rock, originating from shale, and it typically shows well-developed cleavage that allows slate to be split into thin plates. [19] The type of foliation that develops depends on the metamorphic grade. [20]
For example, the protolith of a slate is a shale or mudstone. Metamorphic rocks can be derived from any other kind of non-metamorphic rock and thus there is a wide variety of protoliths. Identifying a protolith is a major aim of metamorphic geology. Protoliths are non-metamorphic rocks and have no protoliths themselves.
Many are made from banded slate or other colored hard stone. They often have a geometric "wing nut" or "butterfly" shape but are not limited to these. More than just functional artifacts, bannerstones are a form of art that appear in varying shapes, designs, and colors, symbolizing their ceremonial and spiritual importance.
