Click here for a data sample
This table contains data related to the geochemical analysis of sediment samples collected from various sites in Finland. The data is sourced from the website of the Geological Survey of Finland (Geologian tutkimuskeskus). The table provides information such as the extraction date of the data, row numbers, unique identifiers, geographical coordinates (easting and northing), map sheet information, material type, width of the sample, velocity, site name, catchment area, sampling date, and various chemical concentrations (co_a61_ppm, co_l, cr_a61_ppm, cr_l, cu_a61_ppm, cu_l, fe_a61_ppm, fe_l, mn_a61_ppm, mn_l, ni_a61_ppm, ni_l, pb_a61_ppm, pb_l, zn_a61_ppm, zn_l). The table also includes information about the fraction, geological geometry (geom_geojson, geom_geotext), geom type, centroid, center coordinates, and the original geometry of the samples. The data in this table can be utilized for various data analytics purposes such as studying the distribution of different chemical elements in sediment samples, analyzing the relationship between chemical concentrations and geographical factors, identifying areas with potential mineral deposits, and investigating the impact of mining activities on water quality in catchment areas.
