The geological structure, relief and paleogeographic evolution of Daujėnai land

Julius Vainorius

The land of Daujėnai is notable for North Lithuanian geological setup, where the geological sections are not complete and karst phenomena are active. The crystalline basement occurs at the depths of 950–1050 m. The dissected pre-Quaternary surface caused the exaration of glaciers. The thickness of the Quaternary cover reaches 15–20 m.

The deposits of surface cover belong to several genetical types of the Last Nemunas Glaciation: glacigenous, glaciolacustrine, glaciofluvial, alluvial and local biogenous (peatbog) deposits as well as the ground formed by human activities.

According to geomorphology, the land of Daujėnai belongs to the geomorphological region of the Mūša–Nemunėlis Plain. Its surface is flat, slightly or moderately undulating reaching 40–70 m absolute height. Relative elevations range from 1–2 m to 4–6 m. The Daujėnai Hill distinguishes itself by a 10-m relative height.

Natural resources of the Daujėnai land are rather modest, mainly, fresh groundwater, gravel and sand.
