The mid- and near-infrared spectra of holmquistite, a lithium-containing orthorhombic amphibole, from Barraute (Quebec, Canada) has been measured The OH-stretching region is characterised by bands around 3660, 3645, 3629 and 3613 cm-1 assigned to (3Mg)-OH, (2Mg + Fe2+)-OH, (Mg + 2Fe2+)-OH and (3Fe2+)-OH, respectively. Based on the ratio between the 3645 and 3660 cm-1 bands Fe2+/(Fe2+ + Mg2+) ratios in the M1 and M3 sites were determined to be in the range between 0.35 and 0.45. In the near-infrared region two times four bands were observed associated with the four possible combination modes of the four M-OH stretching and bending modes around 4029, 4193, 4323 and 4400 cm-1 and with the four overtones of M-OH stretching modes around 7055, 7091, 7123 and 7155 cm-1.
Citation countsare sourced monthly fromand 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.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
