Rusthornite

from Wikipedia, the free encyclopedia

Rosthornite is the name of a fossil resin from the Eocene coal of Carinthia (Austria). The resin was found on the Sonnberg near Guttaring and named by the mining geologist Hans Höfer von Heimhalt in 1871 after the Austrian industrialist Franz von Rosthorn . The rosthornite is a retinite . The botanical origin of the resin is unclear. On the basis of gas chromatographic and mass spectrometric studies, some authors consider a fossil representative from the balsam tree family (Burseraceae) for the resin supplier.
