Gniess on Tiree, Geology.

The Lewisian gneiss on Tiree was transormed at a depth in the earth's crust of many kilometers under great temperature and pressure.

The Isle of Tiree, just twelve miles long, is situated off the west coast of Scotland. It is the most westerly of the Inner Hebrides. The ever present sea, wild birds by the thousand, the quiet roads and record levels of sunshine keeps tourists coming back to Tiree. For details check out the Tiree Map page.
