laaksojaksoja
Laaksojaksoja is a Finnish geoscience term used to describe valley-scale stratigraphic units that record distinct developmental phases of a valley. The singular form is laaksojakso, and the plural is laaksojaksoja. The term derives from laakso (valley) and jakso (period or phase).
Usage and scope: Laaksojaksoja are applied in geomorphology and stratigraphy to identify discrete sequences within a
Characteristics: Each laaksojakso is characterized by its lithology, sedimentary structures, terrace height, soil (paleosol) development, and
Formation and interpretation: Laaksojaksoja form through repeated cycles of sediment deposition during valley filling and incision
Significance: They provide a framework for reconstructing valley history, landscape evolution, and regional climate changes, and
