Selective restite entrainment and peritectic garnet back-reaction in high-maficity S-type

Geochemical data and analysis for ca. 1770 Ma S-type syn-collisional granitoids from the southern Aravalli orogen in NW India. The dataset, authored by Prabhakar Dutta and last updated in May 2026, includes classifications based on albitization, maficity, and silica content, with major and trace element trends. Files are provided in DOC and PDF formats totaling 3.3 MB.

Use Cases

• Modeling biotite dehydration melting of meta-greywacke sources based on major element compositions.
• Investigating the role of selective restite entrainment based on high maficity (FeO^t+MgO) values.
• Analyzing peritectic garnet back-reaction processes based on biotite and K-feldspar abundances.
• Classifying granitoid varieties based on albitization degree, maficity, and silica content as described.

Strengths

• Specific geochemical ranges provided, such as FeO^t+MgO = 5.68–7.95 wt% and biotite abundances of 20–22 vol%.
• Detailed petrogenetic context for high-maficity S-type granites is included in the description.
• Dataset is openly licensed under CC-BY-4.0.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data files are in DOC and PDF formats, which may require extraction for computational analysis.
