Eclogite from Åheim, Norway. Eclogite is a mafic (basaltic in composition) metamorphic rock. Eclogite is of special interest for at least two reasons. First, it forms at pressures greater than those typical of the crust of the Earth. Second, being unusually dense rock, Eclogite can play an important role in driving convection within the solid Earth.

Rare Opalized Wood: "Petrified wood is basically fossilized wood that has had its organic matter replaced by a mineral such as agate, bit by bit, as it decomposes. The wood structure is maintained, but the wood fibers are slowly changed into stone. Sometimes a jasper, quartz, pyrite or even opal(shown above) can be found fossilized in wood."
