Petrographical Analysis of Janjukian and Anglesean Coastal Rocks

Petrographical descriptions and chemical analysis results for sedimentary rock samples collected between Torquay and Airey's Inlet, Victoria. The report includes a classification of rocks and notes on mineral occurrences like glauconite and jarosite. Data was published by the Australian Ocean Data Network, with original analysis conducted in 1947.

Use Cases

• Classifying sedimentary rock types using the petrographical descriptions and the M.A. Condon classification system.
• Analyzing the chemical composition and occurrence of glauconite described in the sample notes.
• Studying the distribution and origin of jarosite based on the 1947 rough chemical analysis results.
• Correlating geological formations between Torquay and Airey's Inlet using the described Janjukian and Anglesean deposits.

Strengths

• Includes specific chemical analysis results from 1947.
• Provides petrographical descriptions for multiple samples from a defined coastal section.
• Applies a named classification system (M.A. Condon) for rock naming.

Limitations

• Sample size and row count are unknown.
• Data is historical, with primary analysis from 1947, potentially limiting modern applicability.
• Original data format is PDF/HTML, requiring extraction for computational analysis.
