Age Determinations of Rock Samples from Geologian tutkimuskeskus, Finland

This table contains data from the 'Geological Survey of Finland' (Geologian tutkimuskeskus) sourced from the country 'Finland' (ISO country code: 'fi'). The table provides detailed information about age determination for various rock samples. It contains columns such as '_extract_date' (date of extraction), '_row_number' (row number), 'gml_id' (GML ID), 'objectid' (unique identifier), 'age_determination_id' (age determination identifier), 'sample_field_code' (field code of the sample), 'map_sheet' (map sheet reference), 'northing' (northing coordinate), 'easting' (easting coordinate), 'ykj_north_original' (original YKJ north coordinate), 'ykj_east_original' (original YKJ east coordinate), 'location' (location information), 'rock_type' (type of rock), 'mineral' (mineral), 'mineral_c12' (C-12 composition of the mineral), 'system' (geological system), 'method' (age determination method), 'number_of_analyses' (number of analyses performed), 'reliability_of_age' (reliability of age determination), 'epsilon_nd_age' (epsilon Nd age), 'published' (published information), 'reference' (reference for age determination), 'comments' (additional comments), 'age_legend' (legend for age determination), 'error_two_sigma_legend' (legend for two sigma error), 'age2_legend' (legend for age determination 2), 'error_two_sigma_legend2' (legend for two sigma error 2), 'age_determined' (determined age), 'error_estimate_two_sigma' (two sigma error estimate), 'lower_intercept_age_u_pb' (lower intercept age U-Pb), 'error_lower_intercept_age' (error for lower intercept age), 'mineral2' (additional mineral), 'mineral2_c30' (C-30 composition of additional mineral), 'age_determined2' (determined age for additional mineral), 'error_estimate_two_sigma2' (two sigma error estimate for additional mineral), 'geom_geojson' (geometry in GeoJSON format), 'geom_geotext' (geometry in GeoText format), 'geom_type' (geometry type), 'geom_centroid' (centroid of geometry), 'geom_center_x' (X coordinate of geometry center), 'geom_center_y' (Y coordinate of geometry center), and 'geom' (geometry information). This data can be utilized in various data analytics tasks such as studying age determinations of rock samples, analyzing rock types and minerals, assessing reliability and errors in age determinations, and exploring geological systems and methods used. The table provides valuable information for geological research and analysis.
