Digital Documentation of Prehistoric East Asian Anthropomorphic Face Jade Specimen 03(EANJ_FACE_03): Morphology, Perforations, Surface Alteration, and Tool Marks

Core Statement This record contains high-resolution visual data of a single prehistoric East Asian face-shaped jade artifact (Object ID: EANJ_FACE_03).The dataset serves as the foundational research base for the digital archiving project of this specimen, intended to provide high-fidelity primary evidence for studies in morphology, traceology, and materials science. Access Control For data security and academic compliance, all high-resolution original files in this dataset are restricted access (Restricted Access). Application requirements:Applicants must submit a clear research proposal and provide institutional affiliation through the Zenodo system. Usage restrictions:All files are limited to visual documentation, comparative study, and non-interpretive morphological research.Any unauthorized commercial use or non-academic distribution is strictly prohibited. Dataset Content This dataset includes the following core files to support detailed morphological analysis: Overview Images High-resolution frontal and rear photographs, documenting overall shape, proportions, and geometry of the artifact. Metric Reference Images Images including metric scales to enable quantitative analysis. Microscopic Evidence Macro photographs of perforation structures (Ox-nose piercing), surface pits (Micro-erosion), and tool marks. Imaging and Processing Notes All images were captured in RAW format and converted to JPEG without local editing. Photography was conducted under controlled lighting conditions with a neutral background to minimize environmental interference. No physical manipulation or surface intervention was applied to the object during photography. If necessary, post-processing was limited to global exposure and white balance adjustments to ensure a visually accurate representation of the material. Compliance and Due Diligence This dataset was prepared following all relevant compliance and due-diligence procedures, including voluntary disclosure and institutional consultation, to ensure academic transparency and legal conformity.
