1. Dataset Identification This dataset contains a high-resolution visual record of a single jade object (Specimen ID: EANJ_LZH_09).The dataset constitutes a standardized digital imaging archive intended to support non-interpretive visual observation, morphological comparison, and image-based reference within academic contexts. 2. Object Record Object type: Jade object (single specimen) Statement of Scope:The morphological designation used here refers exclusively to the overall external features directly observable in the images and serves as a baseline term for image indexing and visual comparison. 3. Imaging Dataset Structure 3.1 Image Categories This dataset includes the following three categories of images: Multi-angle overall views Macro images of surface features and localized structures Reference image including a scale bar 3.2 File Inventory Overall views EANJ_LZH_09_OVERALL_A EANJ_LZH_09_OVERALL_B EANJ_LZH_09_OVERALL_C EANJ_LZH_09_OVERALL_D Macro views EANJ_LZH_09_MACRO_A EANJ_LZH_09_MACRO_B EANJ_LZH_09_MACRO_C EANJ_LZH_09_MACRO_D EANJ_LZH_09_MACRO_E Scale reference image EANJ_LZH_09_SCALE 4.

Data Integrity Statement This dataset represents a static visual record captured at a specific point in time.Its intended use is limited to: Non-invasive visual observation Image comparison and morphological reference Supplementary visual material for academic research 7. Access Classification High-resolution image content in this dataset is released under Restricted Access.Access requests must be submitted via the Zenodo platform and should briefly state: The intended research or teaching purpose Relevant academic or institutional affiliation (if applicable) 8. Usage & Licensing Permitted uses: Academic research Teaching purposes Visual and comparative analysis based on observable features Other uses:Any additional uses—including commercial applications, data redistribution, or dissemination in non-academic contexts—require prior authorization.Access and authorization decisions will be made by the data publisher based on research relevance, intended use, and consistency with the dataset’s non-interpretive research scope.
