Fluor-elbaite, lepidolite and Ta–Nb oxides from a pegmatite of the 3000 Ma Sinceni Pluton, Swaziland: evidence for lithium–cesium–tantalum (LCT) pegmatites in the Mesoarchean

Edward S. Grew, Ferdinando Bosi, Linus Ros, Per Kristiansson, Mickey E. Gunter, Ulf Hålenius, Robert B. Trumbull, Martin G. Yates
Published: 01 March 2018
European Journal of Mineralogy (2018) 30 (2): 205–218.
DOI: https://doi.org/10.1127/ejm/2017/0029-2686
... reported occurrence of a lithian tourmaline and lepidolite in the geologic record, as well as one of the two earliest known examples of the lithium–cesium–tantalum (LCT) family of pegmatites. The Sinceni magma is most plausibly derived from a metasedimentary source by intrusion of hot mantle melts...

Economic mineralization in pegmatites: comparing and contrasting NYF and LCT examples

Kathryn M. Goodenough, Richard A. Shaw, Martin Smith, Guillaume Estrade, Eva Marqu, Cyrielle Bernard, Paul Nex
Published: 30 September 2019
The Canadian Mineralogist (2019) 57 (5): 753–755.

... pegmatites can represent superb deposits of rare metals, including some ‘critical metals' that are important for many modern technologies ( Linnen et al . 2012 , London 2018 ). Notably, the majority of ore deposits associated with granitic pegmatites are found in LCT pegmatites, which represent many...
