Törmelékbl

Törmelékbl is a term used in geology to describe rock fragments that are of a specific size range and angularity. These fragments are typically found in areas where rocks have been broken down by physical weathering processes such as frost wedging, thermal expansion, or impact. The term "törmelék" is Hungarian for debris or rubble, and "bl" is often used as an abbreviation in geological contexts.

The size of törmelékbl can vary, but it generally falls between coarse sand and gravel. More importantly, the fragments are characterized by their sharp, angular edges rather than rounded shapes. This angularity indicates that the material has not been transported over long distances by water or wind, as such processes tend to abrade and round rock fragments. Instead, törmelékbl suggests a relatively localized origin of the broken rock.

Törmelékbl is commonly found in talus slopes, scree deposits, and at the base of cliffs where rockfalls occur. It can also be present in glacial environments where ice action breaks up bedrock. The composition of törmelékbl reflects the parent rock from which it originated. Identifying the type of rock in the törmelékbl can provide clues about the geological history of an area. The study of törmelékbl helps geologists understand weathering patterns, erosion rates, and the geological processes shaping the landscape.
