Re: Icelandic rocks

There are no metamorphic rocks in Iceland, so it can't be schist with garnets. There are only igneous extrusive volcanics, basalts, lavas, and tephra, with some tiny sedimentary shallow sea deposits and swamp deposits with fossils (Miocene). There are rare igneous garnets in other parts of the world, but they occur in intrusive igneous rocks, again not found in Iceland. There are a few localities with agate, jasper, and rare petrified wood. But as to what kind of rocks you have, can't tell from the photographs.
