Prehistoric East Asian Anthropomorphic Face Jade Specimen 05 (EANJ_FACE_05): Digital Documentation of Morphology, Perforations, Surface Evolution, and Tool Marks

1. Core Statement This record contains high-resolution primary visual data of a prehistoric East Asian anthropomorphic jade artifact (Object No.: EANJ_FACE_05). This dataset serves as the foundational scientific baseline for the digital archiving of this specimen, providing high-fidelity primary evidence for morphology, traceology (micro-wear analysis), and material science research. 2. Access Restrictions and Application Guidelines For reasons of data security and academic protocol, the high-resolution original files of this dataset are set to Restricted Access. Application Requirements: Applicants must submit a clear Research Proposal and Institutional Affiliation via the Zenodo system. Usage Restrictions: All data are restricted to visual documentation, academic comparison, and non-interpretative morphological studies. Any form of commercial use or non-academic dissemination without explicit authorization is strictly prohibited. 3. Dataset Composition This dataset includes the following core files designed to support detailed morphological analysis: Panoramic Records: High-resolution original photographs of the obverse and reverse, documenting the overall proportions and geometric structure. Metric References: Comparative images including a metric scale to ensure quantitative analysis capabilities. Dimensions: Length: 7.0 cm; Width: 2.9 cm; Height: 1.4 cm; Weight: 25 g. Microscopic Evidence: In-depth macro-photography targeting the perforation structures (ox-nose piercing), surface pitting (micro-erosion), and manufacturing traces (tool marks). 4. Imaging and Processing Specifications All images were captured in RAW format and converted to JPEG without localized retouching. Photography was conducted under controlled lighting conditions using a neutral background to minimize environmental interference. No physical treatment or surface intervention was applied to the object during the imaging process. Where necessary, post-processing was strictly limited to global exposure and white balance adjustments to ensure the images accurately reflect the material's actual state. 5. Compliance and Due Diligence Prior to compilation, this dataset strictly followed relevant compliance and due diligence procedures, including voluntary disclosure and institutional consultation, to ensure academic transparency and procedural legitimacy.
