Eclogite – Scotland

Eclogite is a rare metamorphic rock, these specimens come from Scotland and exhibit the two major minerals expected, red garnets and green omphacite. However, both minerals appear to be much darker in colour when compared to Norwegian material. Our stock of this is fairly low now, and only smaller size pieces are available, they will come supplied in a card tray with a data label.

Eclogite is an uncommon metamorphic rock, composed of mainly two minerals, reddish-brown garnets and the green pyroxene mineral known as omphacite, other minerals, such as kyanite may also be present. Eclogite is a fairly rare rock, even rarer in this particular locality. It's formation is a result from high-pressure metamorphism of mafic igneous rock (typically basalt or gabbro) as it plunges into the mantle in a subduction zone. Such rocks are generally formed from precursor mineral assemblages typical of blueschist-facies or amphibolite-facies metamorphism, but can also form from magmas that crystallise and cool within the mantle or lower crust of the earth. These particular specimens of eclogite come from Scotland, they however, exhibits a much darker shade of green and red when compared to the material we have from Norway, which appear quite bright in contrast. This material is now limited in stock with only smaller size samples available, which will come supplied in a card tray with an information label.
