Stromatolites

Prelims – General issues on Environmental ecology, Bio-diversity and Climate Change.

Why in news?

Recently, 600-million-year-old stromatolite outcrop has been discovered in Chambaghat, Solan district, Himachal Pradesh.

  • Stromatolites – They are reef-like bio sedimentary structures formed by cyanobacteria (blue-green algae) in ancient shallow seas.

stromotiles

  • Time period – It dates from 3.6 billion years old (Australia) to 600 million years old (recent Himalayan discovery).
  • Distinction from fossils – If original organism is preserved, it's technically a fossil; if only the mineralised structure (calcium carbonate precipitates) is preserved, it's a biosedimentary structure.

Recent Discovery in the Himalayas

  • Location – Pine-clad ridges of Chambaghat in Solan district, Himachal Pradesh.
  • Age – 600 million years old.
  • It is found at 5,000-6,000 feet above sea level in entire hill covered with stromatolites, not just isolated samples.
  • Younger stromatolitesThis is the youngest stromatolites in India.

Oldest stromatolites are found in Dharwad in Karnataka, which are at least 2,500 million years old.

  • Geological significanceIt is part of the Krol Group of sedimentary rocks that is formed in shallow marine environment of the ancient Tethys Sea.
  • It helps to reconstruct the theory of a vanished Tethys Sea in the Himalayan region.
  • These structures indicate the shallow marine conditions that once existed before the Indian plate collided with Eurasian plate.
  • Historical significance – Earth’s atmosphere doesn’t contain oxygen when it is formed and it is composed of carbon dioxide, methane, and water vapor.
  • Oxygen production – Cyanobacteria in stromatolites began producing oxygen through photosynthesis around 3.5 billion years ago.
  • This contributed to the Great Oxygenation Event, making Earth habitable for complex life.

Great oxidation event occurred around 2.4 billion years ago, transforming Earth's atmosphere and enabling multicellular life.

  • ThreatRisk of permanent loss due to development and natural processes such as mining activities, construction and erosion.

Other Stromatolite Sites in India

  • Uttarakhand – Mussoorie, Nainital (Krol Belt formations)
  • Haryana – Morni Hills (dolomite formations)
  • Uttar Pradesh – Chitrakoot (Vindhyan limestones), Salkhan (fossil park)
  • Rajasthan – Jhamarkotra (mining threatened), Zawar, Jaisalmer Fossil Park, Bhojunda, Bilara Group
  • Andhra Pradesh – Kadapa Basin (Cuddapah Supergroup)
  • Madhya Pradesh – Kadapa mountains
  • Chhattisgarh – Chandi Formation
  • Sikkim – Buxa Formation (declared Geoheritage site)

SEBI’s New Framework for Risk Monitoring

Prelims: Economic and Social Development | Current events of national and international importance.

Why in News?

The Securities and Exchange Board of India (SEBI) has come up with a new framework for risk monitoring and increased the position limits for futures and options.

  • SEBI had changed the method to calculate the value of open interest (OI) from notional value-based to delta-based.
  • The new method will weigh OI by the price sensitivity making it impossible to manipulate trades.
  • SEBI has also increased the limits for positions for options.
  • The net end-of-day open interest limit for options will be Rs.1,500 crore and gross OI will be at Rs.10,000 crore.
  • For futures, the OI limits are fixed based on the type of investors ranging from 5% of future OI value to 15% of future OI value.
  • SEBI has decided not to impose limits on intraday trading.
  • Delta-adjusted open interest is a true reflection of the positions taken by traders at large.
  • In effect, positions are being assigned weights as per the delta, making the risk management framework stronger.
  • SEBI has set a phased timeline for exchanges to implement these steps till September.

Revision on Minimum Support Prices (MSP) for Kharif Crops

Prelims: Public policy| Government Initiatives | Current events of national and international importance.

Why in News?

The Centre recently announced minimum support prices (MSP) for 14 crops for the 2025-26 Kharif Marketing Season (KMS), with moong seeing the lowest and ragi the highest increase.

  • Minimum Support Price (MSP) – MSP for a commodity refers to the price at which the government is obligated to purchase the produce from farmers if the market price falls below this threshold.
  • MSPs serve as a baseline for market prices, guaranteeing that farmers obtain a specific minimum compensation to cover their cultivation expenses and potentially generate some profit.
  • By utilising these measures, the government provides incentives for the cultivation of specific crops, thus assuring the maintenance of an adequate supply of essential food grains in India.
  • Revised Prices - In percentage terms, ragi recorded a maximum hike compared to last season.
  • Like ragi, another millet crop, jowar also saw almost a double-digit hike in percentage terms in its MSP.
  • The MSP of jowar (hybrid) and jowar (Maldandi) has been fixed at almost 10% higher as compared to the last Kharif season.
  • The MSP of bajra has been fixed at 5.71% higher compared to the last season.
  • In recent years, the government has been promoting millet crops, including ragi and jowar, and has declared them as Shree Anna.
  • Ragi accounts for just 0.51% of the gross cropped area of the country and is mainly grown in Karnataka, Tamil Nadu and Maharashtra.

Major jowar producing states are Maharashtra, Karnataka, Rajasthan, Tamil Nadu and Uttar Pradesh.

  • Moong, a pulse crop, saw the lowest hike of just 0.99%.

Moong is grown in Rajasthan, Maharashtra, Madhya Pradesh and Karnataka.

  • Like moong, paddy has also seen a low hike in MSP.
  • The MSP for paddy (common) and paddy (Grade A) has been fixed at 3% higher compared to the last season.
  • The reason for the low hike in MSP for paddy is that the government has record stock of rice in the Central Pool.
  • Centre also approved the continuation of the Interest Subvention (IS) component under the Modified Interest Subvention Scheme (MISS) for the financial year 2025-26.
  • Under MISS, short-term credit is provided to farmers at an affordable interest rate through the Kisan Credit Card (KCC).

  • Past Incidents - Notable spills include Hong Kong (2012) and Durban (2017), causing severe ecological damage and highlighting transport risks.
  • Composition & Recycling - Kerala's nurdles are primarily Low-Density Polyethene (LDPE) and High-Density Polyethene (HDPE). LDPE's recycling difficulty complicates waste management.
  • Cleanup and Prevention - Strategies involve manual cleanups, floating booms, improved packaging, rapid response, and strict regulatory enforcement to prevent future spills.
  • Ongoing Concerns - The Kerala incident underscores the persistent threat of plastic waste, raising concerns for biodiversity-rich regions as plastic production increases.

Security

Red teaming
