Abstract

Preliminary notes on a new occurrence of pink corundum (ruby) in Sławniowice (Eastern Sudetes).A b s t r a c t. Grains of light pink and pink-violet corundum (ruby) were recognized in the alluvia of the Maruszka stream cutting the deposit of Sławniowice marble. The grains reach a size of up to 3 mm. They are usually slightly rounded or angular and sometimes barrel-shaped. X-ray powder diffraction and energy-dispersive X-ray spectroscopy analysis of corundum were performed. Mineral inclusions in the corundum grains have been also identified.
