Groundwater Salinity Origins Near Tresco, Victoria, Australia

Core samples and groundwater from bores at Tresco in northwest Victoria have been analyzed for palynology and chemistry. The data describes the chemical evolution of an aquifer from fresh water to saline, influenced by brine pulses between 400,000 and 18,000 years B.P. The dataset is provided by Geoscience Australia Data and was last updated in March 2026.

Use Cases

• Modeling historical groundwater salinity intrusion based on described brine pulse events.
• Analyzing aquifer geochemical evolution paths based on palynology and chemistry data.
• Testing hypotheses for salinity origins, excluding marine sources as described.

Strengths

• Data is tied to a specific geological timeframe, between 400,000 and 18,000 years B.P.
• Analysis includes multiple methods: palynology and chemistry of core and groundwater samples.
• Dataset originates from the authoritative Geoscience Australia Data organization.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
