McKinlay Sheet: Geological Explanatory Notes and Map for Queensland

Queensland's McKinlay Sheet area features geological mapping and explanatory notes from a 1961 survey by the Bureau of Mineral Resources. The notes describe a conformable sedimentary sequence approximately 3500 feet thick, spanning from the Cretaceous Longsight Sandstone to the Upper Cretaceous Winton Formation. The data also includes descriptions of probable Tertiary-age Edkins Formation deposits west of Kynuna.

Use Cases

• Analyze sedimentary basin stratigraphy based on described Cretaceous to Tertiary formations.
• Map historical geological features based on the 1961 field survey data.
• Study the paleo-environment of the ancestral Diamantina River based on descriptions of the Edkins Formation.
• Correlate regional geological units based on described thickness and sequence data.

Strengths

• Based on a field survey conducted by the Bureau of Mineral Resources, an authoritative geological organization.
• Describes a specific geological sequence with an approximate thickness of 3500 feet.
• Provides temporal context with references to Cretaceous and probable Tertiary age formations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in PDF and HTML formats, which may require extraction for computational analysis.
