PorphyriesCu-Au-Mo
- Type
- Cu-Au (Mo) related to an adakitic granodiorite
Adakitic granodiorite pluton (140 to 137 Ma) hosting Cu-Au (Mo) mineralization described as porphyry-type by Fan et al. (2020), in Silurian to Triassic clastic rocks.

| −43 ‰ | 1 | whole rock, altered granodiorite (F-12) Single analysis (F-12). 30.2 ppm B; value ascribed to hydrothermal fluids. The second sample (F-2) resembles those of Tongshankou; its value is not given, the upper bound of the abstract (-9.53 ‰) probably belongs to it. The 16 rocks of the Middle-Lower Yangtze have δ98/95Mo from -0.5 to +0.2 ‰, not split by deposit. | Fan et al. (2020), Molybdenum and Boron Isotopic Compositions of Porphyry Cu Mineralizati… |
