Spinel is a common phase in all samples except 119 19 and occurs as euhedral to subhedral grains in the sample matrix as partially resorbed grains with garnet coronas figure 132c as exsolutions in pyroxenes and as inclusions in garnet.
With the addition of excess silica to a mix spinel periclase and corundum there is rapid formation of additional spinel at temperatures lower than those indicated on the phase diagram of this system.
In an attempt to enlarge the normal spinel phase diagram for the quaternary li ni mn co o system the transformation at moderate temperatures 150 210 c of layered li 05 ni 1 y z mn y co zo 2 rbar3m which were obtained by an ambient temperature extraction of lithium from li 05 ni 1 y z mn y co zo 2 into normal spinel like fdbar3m lini 1 y. Pyroxene spinel stishovite and spinel magnesiowustite stishovite loop in fe rich region. Spinel is a common phase in all samples except 119 19 and occurs as euhedral to subhedral grains in the sample matrix as partially resorbed grains with garnet coronas figure 132c as exsolutions in pyroxenes and as inclusions in garnet. B condensed matter 33 31 1979 is discussed and a modified magnetic phase diagram is suggested for the spinel system ab 2 o 4 in which the a and b sites are partially or completely occupied by magnetic atoms.
