Journal Article
Published: 01 June 1969
American Mineralogist (1969) 54 (5-6): 969–972.
...Donald R. Peacor Abstract Sarcopside occurs as crosscutting sets of laths, oriented approximately parallel to {112} of triphylite at the Bull Moose Quarry, Custer, South Dakota. The textural relations indicate an origin through exsolution and in this respect the material is similar to graftonite...

... by a progressive leaching of Li and by concomitant oxidation of Fe and Mn. The second one involves graftonite, sarcopside and the alteration products of triphylite. It is characterized by a progressive leaching of Ca in oxidizing and hydration conditions. The first step of the second sequence shows an almost...

...C. S. Hurlbut, Jr. Abstract The name sarcopside, originally given by Websky to a mineral mixture from Michelsdorf, Silesia was shown by Čech, Padĕra and Povondra to be an intergrowth of graftonite and another mineral which has now assumed the name sarcopside. In a restudy of this material...

... backscatter diffraction patterns and maps, together with chemical analyses and Fe-Mg-Mn distribution among phosphates, confirm identification of the orthophosphate as sarcopside, chopinite, and farringtonite; no graftonite was found. Phosphates are found as (1) narrow rims between metal and forsterite...
