PYROMORPHITE on MALACHITE

Mounds of deep bottle-green Malachite with a beautiful silky lustre are partly covered with rich mounded clusters of lenticular lemon-yellow Mimetite crystals, many with a wonderfully contrasting powdery lemon dusted surface.  This is a classic example from the famous locality at Rum Jungle near to Batchelor in Northern Territory, Australia.  Where the Malachite is exposed along the edges of the specimen, the radial form of the fibrous structure is nicely exhibited.  The two largest mounds of Mimetite are roughly 1.8 x 1.8 cm and 2.0 x 1.5 cm, with individual crystals of about 2 mm, both having a coliform appearance.  A very showy and attractive specimen of Mimetite on Malachite from the Rum Jungle deposit.
