Witryna1 gru 2013 · Aluminous garnet, (Mg,Fe2+,Ca)3(Al,Cr)2Si3O12, is an important constituent of mantle peridotite (~10%) and of the other abundant upper mantle rock, eclogite (~50%). Its unusual crystal chemistry means that it strongly prefers some trace elements and confers a “garnet signature” on mantle melts.
