Color SEM-CL: Cathodoluminescence Imaging Technique for Sandstone

A poster graphically represents the process of converting a monochromatic cathodoluminescence signal into an RGB image using color filters. The example image is of a lithic-rich sandstone from the Cretaceous Frontier Formation at Oil Mountain, Wyoming. Author Reed, Robert contributed this resource to the Texas Data Repository, last updated on February 12, 2024.

Use Cases

• Visualizing mineral composition and microfractures in sandstone based on the described cathodoluminescence technique.
• Teaching or demonstrating the RGB color-filter conversion process for monochromatic CL signals.
• Analyzing recycled sandstone rock fragments and pre-depositional features as shown in the example image.

Strengths

• Provides a concrete example image from a specific geological formation (Cretaceous Frontier Formation, Oil Mountain, Wyoming).
• Focuses on a specific analytical technique (color-filter conversion for cathodoluminescence).
• Last updated metadata is precise (2024-02-12 05:09:13).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
