Not sure whether one can really define pegmatite as exclusively granitic. There are mafic pegmatites as well. Here is a classic example: Anderson, A. L., 1933, An Occurrence of Giant Hornblendite: The Journal of Geology, v. 41, no. 1, p. 89-98. In fact, judging by the colors only @7:57 those pegmatites may have some mafic affinities.
Meta-Ultramafic pegmatites seem to be associated with Greenbushes and the Kirup prospects. These are shear hosted "abyssal" pegs with pods within migmatite . De-serpentinisation and generation of borosilicate partial melts during emplacement of 2.6ga felsic intrusives and cratonisation of the Balingup terrane 😉 the boron budget at Greenbushes seems very high. Soon we will have several LiOH plants up and running
Great project and talk. Excellent!!!
Great talk.

I love pegmatites
Love this channel but that was a terrible presentation. Very disappointing.
I was thinking the same !!
