The block fields and block streams are widespread in the Pirin Mountains. They are significant in size and are distributed on both relatively flat and sloping surfaces. Their origin is associated with frost weathering, which can subsequently be supplemented by other processes related to the destruction of the material – chemical weathering, fluvial, cryogenic processes, etc. The main aim of the study is to analyze the block field and block stream deposits which will give us a better understanding of their origin and evolution. |
