Named in 1996 by William D. Birch, Allan Pring, P. G. Self, R. B. Gibbs, E. Kleck, Martin C. Jensen, Eugene Edward Foord in honor of John Meurig Thomas [born 15 December, 1932 Llanelli, South Wales, United Kingdom - died 13 November, 2020], a prolific reasearcher and crystal chemist known for his work on heterogeneous catalysis, solid-state chemistry, and surface and materials science, University of Cambridge, Cambridge, England, UK.

Type Locality:

ⓘ Chino Mine (Santa Rita pit; Santa Rita Mine), Santa Rita, Santa Rita Mining District, Grant Co., New Mexico, USA

Possibly identical to phosphofibrite (Kolitsch, 1999; Kampf & Kolitsch, 2008 and Kampf et al., 2009), although the latter appears to be K-deficient (K < 0.5 pfu).
See also the sodium analogue meurigite-Na.

Previously called meurigite (renamed in 2009).
