Abstract
The olivine minette described by Tidmarsh from the Holmead Farm, Lox-beare, contains analcite microphenocrysts in addition to olivine, biotite, clinopyroxene and alkali-feldspar. A new chemical analysis shows that the rock is undersaturated with respect to silica. This is still another example of analcite occurring in a potash-rich rock.Keywords
