Specimens of Salt Pseudomorphs on a limy matrix, collected from the Triassic Aust Cliff in Avon, UK. Salt Pseudomorphs serve as important inicators of paleoenvironmental conditions.

Cleavelandite is a variety of the mineral albite, one of the constituent minerals of plagioclase feldspar, thus is found in areas where pegmatites and granites exists in certain localities around the world. These particular specimens come from Evje, in Southern Norway and as expected, has a pale green colouration to it. As with albite, cleavelandite also exhibits a triclinic crystal habit and has a hardness of 6- 7 on the Moh’s scale of hardness, it is usually found within cavities of other rocks or minerals. It as named in 1823 by Henry J. Brooke in honor of Parker Cleaveland , professor of geology and mineralogy at Bowdoin College in Maine. Our mineral specimens are massive in form with occasional accessory such as smokey quartz or plagioclase or orthoclase feldspar. The specimens were collected by our own staff from Evje and are available in a range of sizes. Each specimen is supplied in a labelled card tray.
