The square-pyramidal Y1 site can host a variety of M\u003Csup>2+\u003C\u002Fsup> and M\u003Csup>3+\u003C\u002Fsup> ions and is the basis for the distinction of several species. The VI-coordinated Y2 site typically is filled with Al, whereas the also VI-coordinated Y3 site may contain Al, Mg, and other cations of similar charge and size. The tetrahedral T1 site is typically vacant but may contain B (less commonly Al); the trigonal T2 site is also typically vacant but may also contain B. Some of the (SiO\u003Csub>4\u003C\u002Fsub>) may be replaced by (H\u003Csub>4\u003C\u002Fsub>O\u003Csub>4\u003C\u002Fsub>), akin to the Si\u003Csup>4+\u003C\u002Fsup> ↔︎ 4H\u003Csup>+\u003C\u002Fsup> hydrogarnet substitution. Among the oxygen that are not part of the silica tetrahedra, there are eight \"O11\" that typically occur as OH, two \"O10\" that are typically O & OH or OH & OH (the latter arrangement notably when Y1 is an M\u003Csup>2+\u003C\u002Fsup> cation). There may also be up to three \"O12\" that in most vesuvianite-group minerals are absent (and are not included here), but may be present particularly when T1 is occupied.\r\n\r\nNote that although the IMA formula denotes the end-member Y3 site filling as (Al\u003Csub>6\u003C\u002Fsub>Mg\u003Csub>2\u003C\u002Fsub>), the composition of the most Mn-rich sample reported in Armbruster \u003Cem>et al.\u003C\u002Fem>, 2002 (sample NC-14-38) more closely conforms to a Y3 site filling of (Mn\u003Csup>3+\u003C\u002Fsup>\u003Csub>4\u003C\u002Fsub>Al\u003Csub>2\u003C\u002Fsub>Mn\u003Csup>2+\u003C\u002Fsup>\u003Csub>2\u003C\u002Fsub>).","Ca\u003Csub>19\u003C\u002Fsub>Mn\u003Csup>3+\u003C\u002Fsup>Al\u003Csub>10\u003C\u002Fsub>Mg\u003Csub>2\u003C\u002Fsub>(SiO\u003Csub>4\u003C\u002Fsub>)\u003Csub>10\u003C\u002Fsub>(Si\u003Csub>2\u003C\u002Fsub>O\u003Csub>7\u003C\u002Fsub>)\u003Csub>4\u003C\u002Fsub>O(OH)\u003Csub>9\u003C\u002Fsub>",[19,20,21,22,23,24,25],"Al","Ca","Mg","Mn","Si","O","H",[19,20,21,22,23,24,25],[28],"APPROVED",2000,2002,"9","B","G","35","0","Tetragonal",23,138,"15.575","11.824",2868.5,2,"Merohedral {110} twinning","Elongated prismatic with dominant {100}, minor {110}, both often with striations, terminated by {101}.","Deep maroon red prisms up to 1.5 cm in length and as rock-forming mineral. \r\n",6,7,3,"3.404","Vitreous","Transparent,Translucent,Opaque","white","Deep red-brown, red, nearly black",[55,56,57,58,59,60],"red","brown","black","colorless","yellow","pink",[52],"None Observed","Conchoidal","brittle","Uniaxial","-","1.7353","1.7236",1.7236,1.7353,"Strong","O dark red to lilac, E near colorless to yellow;\r\ncolor zoning correlating to compositional zoning is common","Hydrothermal alteration (250-400 C) of primary sedimentary and low-grade metamorphic manganese ores.","The Natural History Museum in Bern, Switzerland, NMBE 35474.","Vesuvianite Group.
