Bergartsmaterial

Bergartsmaterial is a geological term used to describe rock material derived from bedrock, including both intact rock and rock fragments found in unconsolidated form. It encompasses solids formed by the weathering, erosion, transport, and deposition of rock as well as primary and secondary fragments that remain within a rock mass. The term is often used in geotechnical, hydrogeological, and construction contexts to distinguish rock-based material from soils and organic matter.

Bergartsmaterial is commonly classified by the origin and type of the rock it derives from. The three major rock families—igneous, sedimentary, and metamorphic—each contribute distinct mineral compositions and textures to bergartsmaterial. In addition, unconsolidated deposits such as gravel, sand, silt, and clay derived from weathering and sedimentary processes are considered bergartsmaterial in many scientific and engineering applications. In practice, the material is routinely evaluated for its suitability as aggregates, building stone, or raw material for cement and other construction uses.

Key properties used to describe bergartsmaterial include mineral composition, grain size and shape, texture, porosity, permeability, strength, and durability. Weathering resistance, cementation, and potential for chemical alteration affect long-term performance in engineering works. Documentation typically involves petrographic analysis, mineralogical and geochemical tests, and, for unconsolidated materials, grain-size distributions and compaction behavior.

Bergartsmaterial plays a central role in geotechnical design, resource extraction, and construction, reflecting the diversity of rock-derived materials available from the Earth’s crust.
