Spongtang Ophiolite Serpentinization Geochemical Analysis

Bikash Ranjan Nayak's research dataset analyzes mineral chemistry and trace elements from the Spongtang ophiolite in Ladakh. It details elemental pathways and paleo-redox conditions during serpentinization across sub-greenschist to eclogite facies. The 20.6 MB document was last updated in April 2026.

Use Cases

• Model serpentinization phase stability using temperature and pressure ranges for lizardite, chrysotile, and antigorite.
• Analyze trace element mobility by comparing concentrations of Ba, U, Sr, As, and Pb between serpentinites and peridotites.
• Assess paleo-redox conditions using data on sulphide mineral assemblages like awaruite and pyrrhotite.
• Study Rare Earth Elements (REE) patterns to understand seafloor alteration and subduction-related fluid overprinting.

Strengths

• Provides detailed mineral chemistry data for Mg, Si, Al, and Fe exchange.
• Defines specific pressure and temperature stability fields for serpentine minerals.
• Compares trace element concentrations between serpentinites and fresh peridotites.

Limitations

• Dataset scale is limited to a 20.6 MB DOCX file, suggesting a focused case study rather than a large collection.
• Sample size and number of individual data points are unknown.
• Data is presented in a document format, requiring extraction for computational analysis.
