EANJ_LZH_06: High-Resolution Visual Data Record of a Jade Object

1. Dataset Identification

This dataset contains a high-resolution visual record of a single jade object (Specimen ID: EANJ_LZH_06).
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.
