This paper is in part a report on the petrologic study of these manganese bearing pyroxenes and pyroxenoids from Balmat but more importantly it provides an integration of these data with that of other workers on synthetic and natural Mn-bearing systems.
Pyroxenes are the most common single-chain silicate minerals. (The only other important group of single-chain silicates, the pyroxenoids, are much less common.) Their structure consists of parallel chains of negatively-charged silica tetrahedra bonded together by metal cations. In other words, each silicon ion in a pyroxene crystal is surrounded by four oxygen ions forming a tetrahedron around the relatively small silicon ion. Each silicon ion shares two oxygen ions with neighboring …
