Study Material

Paper Paper II

Unit 3

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. 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. Barmer Basin (बाड़मेर बेसिन) — Cretaceous-era dinosaur remains and wood fossils; among the richest vertebrate palaeontological zones in western India.
4. Jaisalmer Basin (जैसलमेर बेसिन) — Jurassic marine fossils including ammonites, belemnites, echinoids, and petrified wood; forms the core of any potential Rajasthan geopark.

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.

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

Introduction and Syllabus Scope

The RPSC geography-and-geology syllabus makes UNESCO geoparks and Rajasthan geo-heritage examinable because the topic connects Earth science with conservation policy, tourism and Rajasthan-specific site knowledge. RPSC's official syllabus page lists the 2026 Rajasthan State and Subordinate Services Combined Competitive Exam preliminary syllabus in English with a release date of 09/01/2026, confirming that the revised exam cycle is live on the Commission's syllabus portal.

The RPSC 2026 Paper II, Unit 3 syllabus covers geo-heritage as a sub-theme within Earth Science. Topic #90 sits at the intersection of geology, conservation policy, and tourism. RPSC expects students to link Rajasthan's specific geological sites to the UNESCO framework, articulate the significance of individual fossil localities, and discuss the policy gap in geo-heritage protection.

The topic's PYQ Tier 4 classification, with 1 out of 5 exams and a single 10-mark appearance in 2021, signals that it is not asked every cycle but carries real weight when it appears. The 2021 question rewarded students who could name specific sites such as Akal, Barmer fossil localities and Bundi stromatolites alongside a conceptual framing of UNESCO criteria. Vague answers about Rajasthan's rich geological heritage scored poorly because they did not show site knowledge.

Scope boundaries: Topic #83 covers the broad physiography and geological structure of Rajasthan, including the Aravalli, Vindhyan and Deccan Trap relationships. Do not repeat that structural geology here except where it helps explain a protected or protectable geo-heritage site. This chapter focuses on sites of outstanding geological value that qualify for heritage protection and possible geopark designation. Topic #9 covers heritage and tourism broadly; here, the tourism angle is specifically geo-tourism and its economic potential for Rajasthan's desert, mineral and ravine districts.

The revised syllabus has added environmental and international dimensions to Paper II, making UNESCO-linked topics more examinable than under the older pattern. For answer writing, treat this as a rising-trend topic for 2026: it is not a daily-current-affairs issue, but it can be tested through a contemporary policy frame.

1 5M What is a UNESCO Global Geopark? Why does India have no such designation yet? 5 marks · 50 words

Model Answer

A UNESCO Global Geopark is a protected area with internationally significant geological sites, managed for conservation, education, and sustainable geo-tourism. Established in 2015, there are 213 geoparks in 48 countries. India lacks the designation due to absence of dedicated geo-heritage legislation, weak management infrastructure at candidate sites, and unclear inter-ministry jurisdiction over geological monuments.
