Sub-Cambrian Peneplain
The sub-Cambrian peneplain is an ancient, extremely flat, erosion surface (peneplain) that has been exhumed and exposed by erosion from under Cambrian strata over large swathes of Fennoscandia. Eastward, where this peneplain dips below Cambrian and other Lower Paleozoic cover rocks. The outcrop, exposed parts of this peneplain are extraordinarily flat with relief of less than 20 m. The overlying cover rocks demonstrate that the peneplain was flooded by epicontinental sea, shallow seas during the Early Paleozoic. Being the oldest identifiable peneplain in its area the Sub-Cambrian peneplain qualifies as a primary peneplain. The surface was first identified by Arvid Högbom in a 1910 publication, with Sten Rudberg publishing the first extensive map in 1954. This mapping has been improved upon by Karna Lidmar-Bergström since the 1980s. Extent The Sub-Cambrian peneplain extends as an almost continuous belt along the eastern coast of Sweden for some 700 km from north to south. Near St ...

Sweden
Sweden, formally the Kingdom of Sweden, is a Nordic countries, Nordic country located on the Scandinavian Peninsula in Northern Europe. It borders Norway to the west and north, and Finland to the east. At , Sweden is the largest Nordic country by both area and population, and is the List of European countries by area, fifth-largest country in Europe. Its capital and largest city is Stockholm. Sweden has a population of 10.6 million, and a low population density of ; 88% of Swedes reside in urban areas. They are mostly in the central and southern half of the country. Sweden's urban areas together cover 1.5% of its land area. Sweden has a diverse Climate of Sweden, climate owing to the length of the country, which ranges from 55th parallel north, 55°N to 69th parallel north, 69°N. Sweden has been inhabited since Prehistoric Sweden, prehistoric times around 12,000 BC. The inhabitants emerged as the Geats () and Swedes (tribe), Swedes (), who formed part of the sea-faring peopl ...

Paleoproterozoic
The Paleoproterozoic Era (also spelled Palaeoproterozoic) is the first of the three sub-divisions ( eras) of the Proterozoic eon, and also the longest era of the Earth's geological history, spanning from (2.5–1.6  Ga). It is further subdivided into four geologic periods, namely the Siderian, Rhyacian, Orosirian and Statherian. Paleontological evidence suggests that the Earth's rotational rate ~1.8 billion years ago equated to 20-hour days, implying a total of ~450 days per year. It was during this era that the continents first stabilized. Atmosphere The Earth's atmosphere was originally a weakly reducing atmosphere consisting largely of nitrogen, methane, ammonia, carbon dioxide and inert gases, in total comparable to Titan's atmosphere. When oxygenic photosynthesis evolved in cyanobacteria during the Mesoarchean, the increasing amount of byproduct dioxygen began to deplete the reductants in the ocean, land surface and the atmosphere. Eventually all surf ...

Highland
Highlands or uplands are areas of high elevation such as a mountainous region, elevated mountainous plateau or high hills. Generally, ''upland'' refers to a range of hills, typically from up to , while ''highland'' is usually reserved for ranges of low mountains. However, the two terms are interchangeable and also include regions that are transitional between hilly and mountainous terrain. Highlands internationally Probably the best-known area officially or unofficially referred to as ''highlands'' in the Anglosphere is the Scottish Highlands in northern Scotland, the mountainous region north and west of the Highland Boundary Fault. The Highland (council area), Highland council area is a local government (Scotland), local government area in the Scottish Highlands and Britain's largest local government area. Other highland or upland areas reaching 400 m or higher in the United Kingdom include the Southern Uplands in Scotland, the Pennines, North York Moors, Dartmoor and Exmoor ...

Lapland (Sweden)
Lapland, also known by its Swedish name Lappland, is a province in northernmost Sweden. It borders the Swedish provinces of Jämtland, Ångermanland, Västerbotten, and Norrbotten, as well as Norway and Finland. Nearly a quarter of Sweden's land area is in Lapland. The historical province of Lapland originally extended further eastward. However, in 1809 the Russian Empire annexed the eastern part of Sweden and formed the Grand Duchy of Finland in that territory. This effectively split Lapland into a Swedish part and a Finnish part, both of which still exist today. Swedish Lapland primarily consists of the inland parts of Västerbotten County in the south and Norrbotten County in the north. It has the coldest climates of Sweden, with vast seasonal differences caused by the high latitudes and the inland location. History The history of Lapland is in many ways connected to the history of Norrbotten County and Västerbotten County, since Lapland is a historic region c ...

Fault (geology)
In geology, a fault is a Fracture (geology), planar fracture or discontinuity in a volume of Rock (geology), rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust (geology), crust result from the action of Plate tectonics, plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction, subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the Plane (geometry), plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geological maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone ...

Geological Survey Of Sweden
''not to be confused with the Geologiska föreningen ()'' Geological Survey of Sweden (, SGU) is a Government agencies in Sweden, Swedish government agency that was founded by Axel Erdmann in 1858, that supervises all mineral deposits activities (surveys and extractions) in Sweden, and further the development of knowledge in the field of geology. The institution also has Law of Sweden, the right to issue instructions regarding groundwater administration in Sweden. Description The purpose of the Geological Survey of Sweden is to undertake surveys and provide information on bedrock, soil and groundwater in Sweden. The SGU is in charge of providing local authorities with comprehensive geological information for environmental work and infrastructure planning. The SGU runs the Mineral Resources Information Office in Malå.

Plateaus Of Sweden
In geology and physical geography, a plateau (; ; : plateaus or plateaux), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wider ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, plate tectonics movements, and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. They may be formed by upwelling of volcanic magma or extrusion of lava. The underlining mechanism in forming plateaus from ...
