- Abstract
- The lower part of a shallow profile on volcanic ash from Isla Santa Cruz of the Gal & PRIME;apagos archipelago was found to contain abundant bayerite, a relatively rare Al(OH)3 polymorph, as confirmed by X-ray diffraction and Raman spectroscopy analyses. The bayerite-bearing interval consists of orange-brown colloidal material with high Al and Fe content, and it contains bayerite in the form of pervasive thin coatings along the sides of pores, including planar voids and narrow channels. Associated gibbsite seems to occur as part of the coatings. Bayerite is interpreted to have formed by rapid crystallisation from solutions derived from the Al-rich groundmass. Gibbsite is regarded as the product of an ongoing process of bayerite transformation.
