The hydroxylated nickel carbonates otwayite and paraotwayite — a SEM, EDX and vibrational spectroscopic study

Frost, Ray L., Weier, Matt L., Martens, Wayde N., & Mills, Stuart J. (2006) The hydroxylated nickel carbonates otwayite and paraotwayite — a SEM, EDX and vibrational spectroscopic study. Neues Jahrbuch fur Mineralogie, Abhandlungen, 183(1), pp. 107-116.



The two basic nickel carbonate minerals otwayite and paraotwayite have been studied by scanning electron microscopy, EDX, Raman and infrared spectroscopy. The SEM images of paraotwayite show a mesh like structure with many pores. This leads to the suggestion of a paragenetic relationship between otwayite and paraotwayite in which the carbonate is replaced by sulphate. Raman and infrared spectroscopy shows otwayite to contain predominantly carbonate with some sulphate and the paraotwayite sulphate with some carbonate.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
