Mining area with abundant coal outcrops (lignite). In the natural combustion of coals (pyrometamorphism), clay layers are transformed into a rock, brick-like, consisting mainly of mullite, with varied contents of quartz, cristobalite and hematite. In dumps from coal mines in the area, mullite is frequent.
