#sedimentary geology
- Allogenesis — A process of formation, development, or evolution determined by external factors or forces foreign to the internal structure of the analyzed system. In geology, it refers to the accumulation within a basin of sediments and minerals formed outside of it and mechanically transported; in biology, it defines a secondary evolutionary direction marked by specific adaptations to new local environments, without an increase in general structural complexity.
- Anemoclastics — Clastic rocks, mineral fragments, or sedimentary deposits fragmented, crushed, and structurally shaped by the mechanical action of erosion, abrasion, or transport carried out by the wind (aeolian processes). As an adjective, it describes geological structures or debris formed via wind deflation and corrasion.
- Anthropolit — A fossilized human remain or a human body petrified through incrustation with mineral substances (lime, silica) inside cave sediments or ancient geological layers. This rare technical term is used in fossil studies to denote prehistoric skeletal specimens that have undergone a complete process of diagenesis and structural mineralization.
