Avalonian Fugue
Artwork ID # 2306-39125-14
Some fantastic and wildly contorted rock layering, broken up into fragments of different sizes. These forms were a result of the effects of intense heat and pressure which formed by a complicated layering and folding of molten metamorphic rock. Here we see interlayers of quartzite ( light bands ) and gray mica schist ( dark bands , The location ) is on Marshall Point near Port Clyde, Maine.
This formation was most likely formed when Avalonia, a small continent in the Paleozoic Era, ( 541 to 252 million years ago ) collided with Laurentia ( a large continental craton ) and formed the ancient geological core of North America, including what is presently the northern coastal area of Maine.
