Upper Devonian-Mississippian Volcanic Sequence and Base Metal Deposits in Pelly Mountains

A geological thesis analyzes the stratigraphic, structural, and tectonic setting of an Upper Devonian-Mississippian volcanic sedimentary sequence in the Pelly Mountains, southeastern Yukon. The work investigates associated stratabound base metal sulphide deposits, comparing them to Kuroko-type volcanogenic massive sulphide deposits. It provides detailed trace element data and structural analysis of thrust sheets, batholith intrusions, and fault systems.

Use Cases

• Analyze trace element data from meta-luminous trachytes to infer extensional tectonic settings in mid-Mississippian time.
• Correlate stratabound massive base metal sulphide deposits with the Mississippian volcanic sequence for mineral exploration models.
• Study the structural relationships between imbricate thrust sheets, Upper Cretaceous batholiths, and Tintina Fault strike-slip faulting.
• Model the depositional environment of submarine volcaniclastic material and interbedded flows within the thrust sheet framework.

Strengths

• Provides detailed geological analysis of a specific Upper Devonian-Mississippian sequence.
• Includes trace element data used to classify rock types and infer tectonic settings.
• Compares local base metal deposits to global Kuroko-type mineralization models.

Limitations

• Data is presented as a thesis document in HTML format, not as a structured, queryable dataset.
• Sample data and columnar structure are unavailable for direct computational analysis.
• The geological analysis is focused on a specific local area in the Pelly Mountains, limiting broader regional application.
