Summary
[edit]
| Description |
English: Bands of the metamorphic rock type called gneiss, capped by a light-coloured pegmatite vein, at Pemaquid Point, near Pemaquid Lighthouse in Maine, USA. The gneiss belongs to the Bucksport Formation, formed originally as sedimentary rock during the Silurian period (about 440 to 430 million years ago). Then, during the Devonian period, the sedimentary rock was heated and squashed, which changed the rock into gneiss. Although the pegmatite has not been precisely dated, it may be of Devonian age.
