90. UNESCO Geo-parks and Geo-heritage Sites: Potential of Rajasthan

CORE Key Points at a Glance

1. 1

   UNESCO Global Geoparks (यूनेस्को वैश्विक भू-उद्यान) — established 2015; 213 geoparks in 48 countries as of 2024; no Indian site has received the designation yet.

2. 2

   Akal Wood Fossil Park (अकाल काष्ठ जीवाश्म उद्यान), Jaisalmer — hosts 25 fossilized tree trunks, ~180 million years old (Jurassic); a GSI National Geological Monument since 1974.

3. 3

   Barmer Basin (बाड़मेर बेसिन) — Cretaceous-era dinosaur remains and wood fossils; among the richest vertebrate palaeontological zones in western India.

4. 4

   Jaisalmer Basin (जैसलमेर बेसिन) — Jurassic marine fossils including ammonites, belemnites, echinoids, and petrified wood; forms the core of any potential Rajasthan geopark.

5. 5

   Mandore (मंडोर), Jodhpur — Jurassic-age dinosaur fossil sites confirmed by GSI surveys; one of only a handful of Rajasthan sites with theropod bone evidence.

6. 6

   Bundi stromatolites (बूंदी स्ट्रोमेटोलाइट) — Precambrian-age fossil structures (oldest evidence of life) formed by cyanobacterial mats; 1,600–1,800 million years old.

7. 7

   The Aravalli Range (अरावली पर्वतमाला) is among Earth's oldest fold mountains; the Banded Gneissic Complex (BGC) basement dates to ~3,500 Ma (Archaean), while the Aravalli Supergroup fold event occurred ~2,500 Ma (Proterozoic). Precambrian quartzites, schists, and gneisses constitute major geo-heritage assets.

8. 8

   Geological Survey of India (GSI) (भारतीय भूवैज्ञानिक सर्वेक्षण) has declared 34 National Geological Monuments across India; Rajasthan hosts some of the most significant, including Akal Fossil Park and Barr (Pali).

9. 9

   Thar Desert (थार मरुस्थल) — aeolian geomorphology (wind-formed landforms), relict sand dunes, interdune playas, and fossil river channels offer world-class geopark potential under UNESCO's geomorphological heritage criteria.

10. 10

    Chambal ravines (चंबल खड्ड) — badland topography formed by accelerated erosion of Vindhyan sandstones; a live geomorphological laboratory and potential geoheritage zone.

11. 11

    India's first UNESCO Geopark submission was Lamheta Ghat (Madhya Pradesh) — still under evaluation (2024); Rajasthan must build institutional infrastructure before its own submission.

12. 12

    Rajasthan Geo-heritage Conservation Act — no dedicated state legislation as of 2024; GSI's National Geological Monument framework is the primary legal protection mechanism available.

13. 13

    RPSC 2021 asked a 10-mark question on this topic — the only PYQ appearance — covering UNESCO geopark criteria and Rajasthan's fossil sites; analytical + factual hybrid approach was rewarded.

14. 14

    Geo-tourism (भू-पर्यटन) — tourism centred on geological features — can generate alternative livelihoods in Thar and Chambal regions where conventional agriculture is marginal.

15. 15

    Barr (बर्र), Pali district — unique geological exposure of Precambrian basement rocks with distinctive structural features; declared a GSI National Geological Monument. / पाली जिले का बर्र — प्रीकैम्ब्रियन आधार शैलों का अनूठा भूवैज्ञानिक उद्भेदन; GSI राष्ट्रीय भूवैज्ञानिक स्मारक।
