The major element chemistry of the K-feldspar crystals is remarkably uniform and is compared with analyses of authigenic K-feldspar crystals. This note describes the occurence and chemical composition of porphyroblastic K-feldspar from a new locality in low-grade marbles of the Pan-African Damara Sequence in the Outjo district, Namibia
