Superficial deposits of Finland 1:1 000 000

The Superficial deposits of Finland 1:1 000 000 is based on 'Quaternary Deposits of Finland and Northwestern Part of Russian Federation and their Resources (Sheet 1, Western part)' mapping data. This data is also based on the 1984 map 'Quaternary Deposits of Finland' (1:1 000 000) in the “Geologia” (Geology) folio of the Atlas of Finland, 5th edition (123-126, 1990). Joint scientific and technical planning for the map of the 'Quaternary Deposits of Finland and Northwestern Part of Russian Federation and their Resources' was begun in 1987 while work on the map started in 1988. No field mapping was done for the map, rather the 1:1 000 000 Quaternary map printed in 1984 was supplemented with new data partly obtained from rock aggregate studies and partly from information on superficial deposits gathered in other superficial mapping projects. The map 'Quaternary Deposits of Finland and Northwestern Part of Russian Federation and their Resources' was printed in 1993. The map shows the superficial deposits with colours and symbols and these are classed according to their mode of geological development.

The deposit classes are as follows: pre-Quaternary bedrock exposures (no Quaternary layers); boulder field, physically weathered bedrock; gravelly and sandy till; silty till; clayey till; hummocky moraine ; moraine complex; esker, delta, sandur, sorted marginal formation; interlobate formation (esker); till-covered esker / other till-covered gravel and sand deposit; gravel and sand deposit peripheral to eskers; littoral gravel and sand deposit; fluvial deposit; homogeneous clay and silt deposit; layered (varved) clay and silt deposit; peat deposit. Additionally, drumlins, end moraines, aeolian deposits, and sites of gravel, sand, clay and peat extraction as well as gold panning areas have been indicated with symbols.

The data set was converted to a digital format to meet the needs of the OneGeology-Europe Project for a printed map in 2009. This data did not include drumlins, end moraines, aeolian deposits, and more important sites for the exploitation of superficial deposits (sites of gravel, sand, clay and peat extraction as well as gold panning areas).

In accordance with the 1984 Quaternary map (1:1 000 000) the minimum size of the deposit polygon is generally one square kilometre. In nature the size of superficial sedimentary deposits is usually smaller than one square kilometre and therefore the most common deposit type in the area is shown in the polygon. In places, deposits smaller than a square kilometre that are significant from a superficial perspective have been noted. As a rule, the narrowest point of the deposit polygon was 0.5 km and in important cases, for example on eskers, 0.3 km. As an exception, the size of small eskers has been exaggerated.

Coordinate reference system of the Superficial deposits of Finland 1:1 000 000 was transformed in October 2013. The transformation from Finnish National Grid Coordinate System (Kartastokoordinaattijärjestelmä, KKJ) Uniform Coordinate Frame to ETRS-TM35FIN projection was done by using the three-dimensional transformation in accordance with the recommendations for the public administration JHS154.

The water layer which were used in the OneGeology-Europe project was replaced in 2015 with the more accurate water layer of the Topographic database 1:55 0000-1:500 000 (DVE3) from ICT Agency HALTIK.

The scanned and georeferenced map was converted to vector format with the TNTmips program. Further processing of the vector lines was carried out with the FINGIS program.

Statement

A 1:1 000 000 Quaternary map printed in 1984 has been used as background material for the data set of the 1:1 000 000 map of 'Quaternary Deposits of Finland and the Northwestern Part of the Russian Federation'. The 1984 map has been supplemented with new superficial data in part from sand and gravel appraisal work and from other superficial mapping work.

The realisation of the 1:1 000 000 map of ‘Quaternary Deposits of Finland and the Northwestern Part of the Russian Federation’ data set benefited from a 1:1 000 000 Quaternary map printed in 1984 as well as superficial maps completed since at different time and scales and superficial data gathered in rock aggregate studies. The map 'Quaternary Deposits of Finland and Northwestern Part of Russian Federation and Their Resources' was printed in 1993.

Coordinate reference system of the Superficial deposits of Finland 1:1 000 000 was transformed in October 2013. The transformation from Finnish National Grid Coordinate System (Kartastokoordinaattijärjestelmä, KKJ) Uniform Coordinate Frame to ETRS-TM35FIN projection was done by using the three-dimensional transformation in accordance with the recommendations for the public administration JHS154.

The water layer which were used in the OneGeology-Europe project was replaced in 2015 with the more accurate water layer of the Topographic database 1:55 0000-1:500 000 (DVE3) from ICT Agency HALTIK.
