COVER: An exceptionally well-preserved orthopyroxene megacryst containing garnet lamellae, juxtaposed against granular harzburgite, from the Bultfontein pans, Kaapvaal craton. Garnet lamellae are homogeneously distributed within the host orthopyroxene and occur at an orientation that is unrelated to orthopyroxene cleavage, strongly indicating that they formed by exsolution. See “An exsolution origin for Archean mantle garnet” by Tomlinson et al., p. 123–126 in the February 2018 issue of Geology.
