abstract = {The paper presents a new finding of lustrous coal particles in the youngest flysch sediments of the Silesian Nappe, Eastern Outer Carpathians, outcropped in the Bieszczady Mountains.

The paper presents a new finding of lustrous coal particles in the youngest flysch sediments of the Silesian Nappe, Eastern Outer Carpathians, outcropped in the Bieszczady Mountains.
