Both minerals are triclinic, their structures are closely related to the parent structure, i.e. the 'tsumcorite type' (C2/m, Z = 2).

Near-Infrared Spectroscopy of Uranyl Arsenates of the Autunite and Metaautunite Group
Near-Infrared spectroscopy of uranyl arsenates of the autunite and metaautunite group Ray L. Frost•, Onuma Carmody, Kristy L. Erickson and Matt L. Weier Inorganic Materials Research Program, School of Physical and Chemical Sciences, Queensland University of Technology, GPO Box 2434, Brisbane Queensland 4001, Australia. Frost, Ray and Carmody, Onuma and Erickson, Kristy and Weier, Matt (2005) Near- Infrared spectroscopy of uranyl arsenates of the autunite and metaautunite group. Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy 61(8):1923. Copyright 2005 Elsevier Note: This is the authors’ version of the work. Abstract A suite of uranyl arsenates have been analysed by Near-infrared spectroscopy. The NIR spectra of zeunerite and metazeunerite in the first HOH fundamental overtone are different and the spectra of uranyl arsenates of different origins in the 6000 to 7500 cm-1 region are different. NIR spectroscopy provides a method of determination of the hydration of uranyl arsenates and has implications for the structure of water in the interlayer. Such a conclusion is also supported by the water OH stretching region where considerable differences are observed. NIR is an excellent technique for the study of the autunite minerals and may be used to distinguish between different autunite phases such as the partially dehydrated autunites for example zeunerite and metazeunerite. Keywords: abernathyite, autunite, heinrichite, novacekite, zeunerite, metazeunerite, near-IR spectroscopy Introduction The study of uranium minerals is important for the remediation of soils, the solution of environmental problems caused by radioactive materials and the uptake of radionuclides from aqueous systems. Among the many uranium minerals are a group of minerals which are very common worldwide known as the autunite group of minerals.
