In recent years, a novel variety of jade known as “African Dulong Jade” has emerged in the jewelry market of Western Yunnan. It possesses a distinctive, vibrant green hue adorned with intricate veins and feathery patterns, juxtaposed against a colorless greyish-white matrix, occasionally tinged with reddish-brown tones. Notably, its quality surpasses that of the “Dulong Jade” found in the Nujiang Prefecture Yunnan Province, exhibiting promising market expansion prospects.However, the gemological characteristics and mineral species of this jade remain mysterious.To shed light on this subject, this research explores the mineral composition, structural characteristics, chemical components, spectral attributes, and the origin of its captivating color. Employing advanced analytical instruments such as the Infrared spectrometer, Raman spectrometer, X-ray powder diffractometer, Scanning electron microscope, Energy dispersive spectroscopy, X-ray fluorescence spectrometer, and Ultraviolet-visible spectrometer, the study delves into a comprehensive investigation.The infrared spectrum examination reveals that the green portion of the jade exhibits mixed infrared spectrum characteristics akin to both muscovite and quartz. Notably, infrared absorption peaks at 3 623, 1 080, 694 and 1 619 cm-1 signify the presence of muscovite. Raman spectra demonstrate that the matrix component of the jade corresponds to α-quartz, as evidenced by characteristic peaks observed at 204, 262, 355, 395 and 463 cm-1. Conversely, the green section of the jade displays muscovite characteristics with peaks highlighting at 261, 395, 694 and 3 623 cm-1. Furthermore, the metallic luster observed on the surface of the mineral signifies the presence of pyrite, with characteristic peaks at 343, 379, and 437 cm-1. Locally disseminated orange-yellow to reddish-brown minerals are identified as hematite, exhibiting characteristic peaks at 224, 295, 409, 493 and 610 cm-1. X-ray powder diffraction analysis confirms the existence of 2M1 muscovite with discernible diffraction peaks observed at 3.489, 2.981 and 2.563 . Insights obtained from scanning electron microscope and energy spectrum scanning elucidate that muscovite manifests as columnar and scale-like aggregates, featuring individual particle lengths ranging from 25 to 40 μm and widths of 2 to 4 μm. Additionally, gersdorffite, an impurity mineral, exhibits minimal content and particle sizes of approximately 10 to 15 μm. Within gersdorffite, iron (Fe) and cobalt (Co) elements partially replace nickel (Ni) through isomorphism. Moreover, the greater concentration of arsenic (As) compared to sulfur (S) suggests a high-temperature hydrothermal deposition origin.Through chemical composition analysis and ultraviolet-visible spectra examination, it is ascertained that the chromogenic mineral muscovite contains barium (Ba) and chromium (Cr), while iron (Fe) is lacking in the quartz matrix. Furthermore, the content of Ba exceeds that of Cr, which acts as the chromic element within muscovite. Beyond color characteristics, this study reveals distinguishing chromogenic elements, chemical composition, and impurity minerals between “African Dulong Jade” and “Dulong Jade” from NujiangPrefecture Yunnan Province using various spectral techniques.These findings serve as compelling evidence for differentiating the two “Dulong Jade” types and contribute to an enhanced understanding of the component information and spectral characteristics of naturally occurring green quartzite jades. Consequently, it establishes a foundation for future inquiries into the metallogenesis geological background and geographical origin tractability of “African Dulong Jade”.
