Original Image Dataset – Close-up Images of Martian Analogue Rocks

This dataset contains original images of Martian analogue rocks, which were analysed in the publication “Close-up Imaging of Oxia Planum Analogue Samples Under Different Illumination Conditions: Preparing for the ExoMars Rover Mission” by Ligeza et al., 2025 (https://doi.org/10.3389/fspas.2025.1530408).
The purpose of this dataset is to make the original high-resolution images publicly available for further analysis, e.g., image processing or image analysis.

It consists of the following documents:

• A – Image Acquisition Procedure: Explains the process for replicating the image dataset with the same or similar analogue rocks. It includes the steps to recreate the analogue lighting conditions on Mars, representing midday, morning/evening, and diffused light (e.g., during the dust storm season), as well as the image acquisition parameters used for the CLUPI analogue camera (Canon EOS M50).
• B – Samples Summary: Contains image IDs and specifications.

It also includes folders with the images, grouped as follows:
1. Clastic sedimentary rocks
2. Rocks with Fe-Mg phyllosilicates
3. Igneous rocks
4. Evaporites, carbonates, and morphological biosignatures
5. Rocks with various morphological features
