Version History of Lithostratigraphic Units in GTK Bedrock Dataset

This table, sourced from the Geoscience Research Center website of Finland, contains the version history of the 'Kalliopera WFSRyhma Muodostuma Litostratigrafiset Yksikot - Ryhma Muodostuma Litostratigrafiset Yksikot' base table. It tracks the changes made to the base table rows over time, providing information on when each row was extracted from the data source ('_start_date') and when a new version of the row was extracted ('_end_date'). The table includes various columns capturing details such as row number, GML ID, object ID, geological time periods (eon, era, period, chronostratigraphic unit, epoch), rock classifications (supersuite, suite, lithodeme, rock class, rock name), shape metrics (area, length), nicknames, geological phases, supergroups, group columns, formations, members, complexes, and various geometry-related attributes. The table can be utilized in data analytics to study the evolution of geological features and their characteristics over time, analyze rock classifications and their distribution, examine spatial patterns using geometry-related attributes, and perform temporal analysis of geological phases and their relationships within the dataset.
