Silurian to Devonian A-Type Granite Geochemistry from the East Kunlun Orogenic Belt

A 504.0 KB DOCX file authored by Bin Liu, last updated on 2026-05-15. It presents a geochemical study of A-type granitic intrusions from the East Kunlun Orogenic Belt, dated to the Silurian and Devonian periods. The analysis focuses on the Balong, Binggou, and Yuejinshan intrusions to investigate magma origin and geodynamic evolution.

Use Cases

• Classifying granite types (A1 vs A2) based on geochemical signatures like Ga/Al and FeOt/(FeOt+MgO) ratios.
• Modeling crust-mantle interactions during orogeny using isotopic and elemental depletion patterns.
• Investigating the role of slab break-off in triggering crustal melting during the Silurian to Devonian period.

Strengths

• Focuses on three specific, named intrusions (Balong, Binggou, Yuejinshan) with reported ages (~423 Ma and ~391 Ma).
• Compares geochemical affinities to a comprehensive dataset of Silurian to Devonian A-type granites identified in the region.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is a 504.0 KB DOCX file, indicating a limited scope likely focused on textual analysis and figures.
