Macquarie Ridge Complex Basalt Thin Section Images contain plane-polarized and cross-polarized microscope images of basalt samples. The collection includes samples from Macquarie Island and dredge samples collected during the TAN0803 voyage in 2008. Thin sections were prepared by Spectrum Petrographics and imaged using a Zeiss Axio microscope at Curtin University.
Use Cases
- Classify basalt samples based on mineral composition visible in plane-polarized and cross-polarized images.
- Analyze textural features like grain size and crystal orientation in images from Macquarie Island and dredge samples.
- Train computer vision models to identify specific minerals within the thin section images.
- Compare petrographic characteristics between samples collected in 2008 and 2017.
Strengths
- Images captured using a standardized Zeiss Axio microscope system.
- Includes samples from two distinct collection events (2008 voyage and 2017 field trip).
- Provides both plane-polarized and cross-polarized light views for each thin section.
Limitations
- Unknown total number of images or samples.
- No associated quantitative data (e.g., chemical composition) is described.
- Last update was in May 2019.
