Pargasiter
Martin Okrusch, Theodore E. Bunch(1973) Al-Rich Pargasite, American Mineralogist, Volume 58, pages 721-726, refers to an analysis performed by Bernard Leake: "The most Al-rich amphibole within this group, from a corundum-zoisite-amphibolite at Merkerstein( N.Arusha, Tanzania), is rather close to the theoretical pargasite composition: Si, 6.05; AlIV, 1.95; AlVI1.04; Na + K, 0.79, and Ca * Na + K, 2.60 (Leake,1971,Table1 )"

Cedric Simonet (2000): “Geology of Sapphire and Ruby Deposits -The example of the John Saul Ruby Mine, Mangare area, Southern Kenya” PhD Thesis, University of Nantes provides a very detailed account of the locality and he has microprobed 4 samples of the dark amphibole embedded in the green zoisite. All of them turned out to be pargasites, all quite similar to:
