thin section scans rockPTX

Each thin section was first scanned in unpolarized light and then again between two sheets of crossed polaroid film aligned parallel to the thin section edges. Originally, "plane polarized" scanning in separate EW & NS orientations was attempted to highlight pleochroic variation, but this ultimately had to be abandoned due to significant

Malachite: The mineral malachite information and pictures

Malachite is a popular mineral with its intense green color and beautiful banded masses. The banded specimens are formed by massive, botryoidal, reniform, and especially stalactitic Malachite that are dense intergrowths of tiny, fibrous needles. Dense banded specimens are often sliced and polished to bring out their beautiful coloring. The bands may consist of concentric rings with interesting
