Groundwater Salinity Origins Near Tresco, Victoria, from Core Samples

Geoscience Australia Data provides core sample and groundwater analysis from bores at Tresco in northern Victoria. The data describes an aquifer's chemical evolution from fresh water to saline, influenced by brine pulses between 400,000 and 18,000 years B.P. The analysis rules out a marine origin for the observed salinity patterns.

Use Cases

• Modeling historical groundwater chemistry evolution based on described palynology and chemical analysis.
• Investigating the impact of surface brine pools on aquifer salinity based on the described invasion mechanism.
• Reconstructing Pleistocene climatic and hydrological conditions in the Murray Basin based on the aquifer's described chemical changes.

Strengths

• Analysis includes both palynology and chemistry data from core samples and groundwater.
• The description provides a specific time range for saline invasion events: between 400,000 and 18,000 years B.P.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing on a single location.
