      The main landscape complexes are relief, soil and vegetation cover, a layer of loose sediments, weathering crusts, bedrock, soil-ground, marsh and surface waters. All the components of the landscape are closely interrelated and depend on the geological structure, neotectonics and the climate of the area. collects information on Finland’s Arctic policies and on Arctic research and Arctic business in Finland. The site is maintained by the Arctic Centre at the University of Lapland with the support of The Ministry for Foreign Affairs of Finland.. Data protection and cookies.

      The large range of chemical variation within intimately associated highly magnesian volcanic rocks in the Palaeoprolerozoic Central Lapland Greenstone Belt prompted the construction of a new classification scheme for MgO-rich volcanic rocks, based on an [Al2O3] vs [TiO2] diagram where the axes are the Al2O3 and TiO2 contents (in mole proportions) of the rocks projected from the olivine.   Here, in the port of Kemi, where the forests of Finnish Lapland stretch down to the shores of the northern tip of the Gulf of Bothnia, 60 miles short of the Arctic Circle, the temperature can drop.

        The topography of Finland is relatively gentle with low, flat or rolling plains and low hills. The land is also dotted with many lakes—more t—and the highest point in the country is Haltiatunturi at 4, feet (1, m) above sea : Amanda Briney. High‐resolution palaeolimnological data from a number of remote and nonpolluted lakes in Finnish Lapland reveal a distinct change in diatom assemblages. This parallels the post‐19th century Arctic warming detected by examination of long‐term instrumental series, historical records of ice cover and tree‐ring measurements.

This list may not reflect recent changes (). The geology of Finland is made up of a mix of geologically very young and very old materials.

Common rock types are orthogneiss, granite, metavolcanics and metasedimentary rocks. On top of these lies is a widespread thin layer of unconsolidated deposits formed in connection to the Quaternary ice ages, for example eskers, till and marine topographic relief is rather subdued because.

A special feature in Finnish geology is the very old bedrock and the much younger surficial deposits lying on top of it. Finland’s geological history is extremely long.

The history of bedrock goes up to 3,5 – 3,7 Ga ago when the old Archaean basement was developed(Fig. The oldest stone in Finland and in the.
