The GTK’s Mineral Deposit database contains all mineral deposits, occurrences and prospects in Finland. Structure of the new database was created in 2012 and it is based on global geostan-dards (GeoSciML and EarthResourceML) and classifications related to them. The database is in Oracle, data products are extracted from the primary database. During 2013 GTK’s separate mineral deposit databases (Au, Zn, Ni, PGE, U, Cu, Industrial minerals, FODD, old ore deposit database) were combined into a single entity. New database contains extensive amount of information about mineral occurrence feature along with its associated commodities, exploration activities, holding history, mineral resource and re-serve estimates, mining activity, production and geology (genetic type, host and wall rocks, min-erals, metamorphism, alteration, age, texture, structure etc.) Database will be updated whenever new data (e.g. resource estimate) is available or new deposit is found. Entries contain references to all published literature and other primary sources of data. Also figures (maps, cross sections, photographs etc.) can be linked to mineral deposit data. Data is based on all public information on the deposits available including published literature, archive reports, press releases, companies’ web pages, and interviews of exploration geologists. Database contains 33 linked tables with 216 data fields. Detailed description of the tables and fields can be found in separate document. (http://tupa/metaviite/MDD_FieldDescription.pdf) The data products extracted from the database are available on Mineral Deposits and Exploration map service (http://gtkdata.gtk.fi/MDaE/index.html) and from Hakku -service (http://hakku.gtk.fi).
The Regional Till Geochemical Mapping data set gives information on the concentrations of 37 elements in unaltered basal till. The samples have been taken, in 1983, from an unaltered basal till (C horizon) below the groundwater table at a depth of ca. 70 cm (variation 50-200 cm) with a density of one sample per 300 km2. The data set covers the whole of Finland with a total sample amount of 1056. The samples are composite field samples. The calculated sample point coordinates entered in the data set have been obtained from the centroid coordinates of five subsamples. The subsamples have been collected from a 300 m x 1000 m rectangular-shaped area. In Northern Finland, samples have been obtained by including samples taken previously in the Nordkallot Project. The samples have been sieved for analysis at a grain size grade less than 0.06 mm. The samples have been analysed for total elemental concentrations and aqua regia concentrations. Total concentrations have been determined either by neutron activation analysis (method code 900N) or by total dissolution with strong concentrated mineral acids (method code 312P). The analysis code for aqua regia dissolution is 511P. Gold and palladium have been determined with a analysis method based on flameless atomic absorption (519U). The sulfur concentration has been determined with a LECO analyser (810L). Further, total concentrations (312P) and aqua regia soluble concentrations (511P) were determined from Southern Finland and Mid-Finland samples with a grain size grade less than two millimetres. The original purpose of the Regional Till Geochemical Mapping data set was national geochemical general mapping and ore exploration. Other uses are, for example, estimating the baseline concentration of the soil, the nutrient levels of forest soil, assessing the buffering capacity of base cations in the soil and evaluating the weathering rate.
Bedrock of Finland 1:200 000 is a unified bedrock map dataset covering the whole Finland. It has been compiled by generalising the scale-free bedrock map feature dataset. The dataset consists of a lithological/stratigraphic geological unit polygon layer and linear layers, in which faults, diverse overprinting lines and dykes are represented. The dataset also includes an origin of the data and a quality estimation of the data polygon layers. The stratigraphic geological unit polygon layer includes lithological coding, geological time period and hierarchical lithostratigraphical or lithodemic classification as attributes in accordance with the Finnish database for stratigrafic geological units (Finstrati). The line layers have their own hierarchical classification. The data are at 1:200 000 scale, which indicates that the main part of the scale-free data have been generalised to correspond to a product at a scale of 1:200 000. Those areas where the source data is coarser than 1:200 000 have not been generalised. Coordinate reference system of the dataset was transformed in March 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 Rock Geochemical Database of Finland data set describes the concentrations of major and trace elements in the bedrock of Finland. In all, 6544 samples were analysed for the total and partial concentrations of 57 elements using several different methods (XRF, ICP-MS, ICP-AES, GFAAS). The samples were taken during 1990-1995 with a mini-drill from rock that was as unaltered as possible. The sampling density varies between one sample per 30 km2 and one sample per 120 km2. The chemical analyses of the data were performed during 1992-2001. The reproducibility of the analytical results and the analytical drift were estimated using 375 duplicate sample pairs. The lowest reliable concentration was determined for each element and analytical method. In addition to the chemical concentrations, the database contains spatial data and several geological attributes for each sample. The data set and its manual were published in 2007 and they are available via the web site of the Geological Survey of Finland (GTK).
