Highlights

• Guano decomposition minerals include a significant nano-particulate silica component
• Berlinite is reported from a low temperature cave regime
• Fluorapatite efflorescences highlight significant, mobile, fluorine content of ancient guano

Abstract

Recent studies of ancient bat guano deposits in the caves of Gunung Mulu National Park and Niah National Park, Sarawak, Malaysia, have resulted in noteworthy records of phosphate minerals from these environments, including variscite, nano-particulate silica, fluorapatite, and niter.
