[1] It is generally located in regions rich in sulfur and commonly occurs alongside other sulfosalts.
[5] Bursaite was discovered in a contact zone between a set of marbles and granites amidst the Uludağ massif in Bursa, Western Turkey, by scientist Rasit Tolun in 1955.
[1] Tolun was also the first to study the chemical composition of bursaite via flotation and superpanner tests.
The specimen was also chemically analyzed via X-ray spectroscopy and contained 4.24% pyrite, 4.78% blende, 5.48% bismuth and 85.3% Pb5Bi4S11.
It is composed of many prismatic crystals, which generally form along the [100] axis, intertwined with long, plate-like grains.
[4] In a microscope, bursauite shows distinct high reflective power and oblique extinction.
Close to its discovery grounds, it commonly occurs in Uludağ, Turkey, around a metamorphic scheelite deposit near Bursa.
[2] Bursaite commonly occurs alongside other sulfosalts, such as sphalerite, pyrite, chalcopyrite, bismuth and scheelite.
In 1956, Michael Fleischer of the American Mineralogist noted that bursaite's X-ray data shows many coincidences between those of the minerals kobellite and cosalite.
[4] Given this information, it was inferred that bursaite is an intergrowth of two sulfosalt phases, derived from lillianite.
