The Ilindenski Kamak is situated along the Ilindenska river valley, northwest of Chelopech village, and is composed of different types of volcanic and volcaniclastic rocks, which are interbedded by sandstones and mudstones, all of Late Cretaceous age. The architecture of the pile of extrusive andesitic rocks is interpreted as a subaqueous cryptodome or sill. The presented research deals with a variety of volcanic facies: 1, coherent andesitic domain; 2, quench fragmented domain (closely packed peperites); 3, globular peperites developed at the contact of wet, unconsolidated sediments.
