Type Occurrence of HoneaiteHide

Place of Conservation of Type Material:
Type material is deposited in the mineralogical collections of the Natural History Museum, London, catalogue number BM 2015, 36.
Geological Setting of Type Material:
Microvugs and microfractures mostly in areas where amphibolite underwent prehnite alteration, as a part of (likely) greenschist-facies mineralization under relatively low temperatures
