Our international team, in collaboration with numerous regional experts, has compiled comprehensive details on geologic formations within the Indian Plate, spanning the Proterozoic to Quaternary periods. This compilation encompasses nearly 1000 sedimentary and volcanic formations across India, Pakistan, Nepal, Bhutan, Sri Lanka, Bangladesh, Myanmar, and offshore hydrocarbon exploration basins. Each formation entry includes information on lithologic succession, fossil content, age range, regional extent, and available visual representations. Geologic age spans are converted to numerical ages using the Geologic Time Scale 2020, and regional extents are encoded as GeoJSON. APIs are provided for open access to facilitate integration with other applications. The cloud-based database and website (temporarily at
indplex.geolex.org/index.php) can be explored through a user-friendly map and stratigraphic-column interfaces generated from
TimeScale Creator software.
The display output also offers the option to visualize the individual formation as facies-pattern-filled polygons projected onto plate reconstructions of the appropriate age. The Indian Plate database interlinks with other online regional lexicons, such as those of China and Indochina, to facilitate display of time slices of regional paleogeography.
The suite will be eventually hosted and maintained by the Geological Society of India in collaboration with partners from Pakistan and other nations. It will be interlinked to other stratigraphic databases through the lUGS Deep-Time Digital Earth platform to enabling the generation of paleogeographic visualizations for any desired geologic age and plate-motion model. This comprehensive approach enhances our understanding of deep-time dynamics and fosters insights into the evolution of the Indian Plate.
