Formation of Fe–Si–Mn oxyhydroxides at the PACMANUS hydrothermal field, Eastern Manus Basin: Mineralogical and geochemical evidence
Z Zeng, H Ouyang, X Yin, S Chen, X Wang… - Journal of Asian Earth …, 2012 - Elsevier
Samples of Fe–Si–Mn oxyhydroxides were collected from the PACMANUS hydrothermal
field, which lies in a young back-arc setting in the Eastern Manus Basin. The purpose of the
study was to understand the origin and characteristics of Fe–Si–Mn oxyhydroxides
associated with massive sulfides in a back-arc basin. The PACMANUS Fe–Si–Mn
oxyhydroxides are composed of Fe oxyhydroxides and Mn oxyhydroxides with opal-A and
nontronite; they have very low concentrations of trace elements (except for Ba, Mo, V and U) …
