Geological Map of Haggart Creek-Dublin Gulch Area in Yukon

A geological thesis map details a four-by-ten-mile strip extending from Potato Hills summit, approximately thirty miles north of Mayo, Yukon. It documents Precambrian quartzites, metamorphic folding phases, a granodiorite intrusion with a 500-foot aureole, and silver-lead-antimony vein mineralization. The work analyzes Pleistocene cover impacts and fault disruptions.

Use Cases

• Map the distribution of quartzites and phyllite interbeds within the Precambrian Yukon Group for regional stratigraphy.
• Analyze the two distinct phases of folding recorded in the bedrock to model structural geology and deformation history.
• Study the 500-foot-wide thermal metamorphic aureole containing corundum around the granodiorite stock for contact metamorphism research.
• Catalog the mineralogy of silver-lead-antimony veins, including jamesonite and galena, for economic geology and mineral exploration models.
• Assess the modification of topography by two stages of Pleistocene ice advance for geomorphological studies.

Strengths

• Provides detailed field mapping for a defined four-mile by ten-mile geological area.
• Documents specific mineral assemblages, including jamesonite and corundum, within distinct geological features.
• Analyzes multiple geological processes: regional metamorphism, two folding phases, intrusion, and faulting.

Limitations

• Exposure is noted as poor in many parts due to thick Pleistocene cover, limiting direct bedrock observation.
• Sample data and structured tabular columns are unavailable, restricting quantitative analysis.
• The primary format is an HTML thesis, which may require manual extraction of map and descriptive data.
