Divergent drift of Adriatic-Dinaridic and Moesian carbonate platforms during the rifting phase witnessed by triassic MVT Pb-Zn and SEDEX deposits; a metallogenic approach [PDF]
, 2016 Early-intracontinental rifting of Pangea is result of thermal doming in Uppermost Permian time giving rise to the formation of horst-graben structures, followed by slow subsidence, marine transgression and evaporate deposition.

Journal of Spectroscopy, Volume 2018, Issue 1, 2018., 2018 ZnO, Zn(OH)2, Zn5(OH)8Cl2·H2O, ZnCO3, and Zn5(CO3)2(OH)6 synthetic powders were prepared by chemical or solid‐state method. Their crystalline phase structure, thermal behavior, and morphology were examined. Characteristic infrared absorbance bands were estimated by means of FT‐IR ATR spectroscopy.

Journal of Near Infrared Spectroscopy, 2006 Near infrared (NIR) spectroscopy has been applied to the study of selected calcite group minerals including smithsonite, rhodochrosite, sphaerocobaltite and cadmium smithsonite. The isomorphic substitution of calcium in calcite group minerals by divalent cations such as Fe, Cu, Cd, Mn, Mg, Co, Zn is in agreement with variable spectral properties ...

Origins of Colour of Smithsonite from Yunnan, China
Minerals, 2023 Smithsonite exhibits an extensive range of colours in nature. The internal features, spectral characteristic, and trace elements of several coloured smithsonites (e.g., white, blue, blue-green, yellow, orange, and pink) from Lanping District, Yunnan Province, China, were analysed and the relationship between smithsonite colour and trace elements and/or
