【Abstract】 Garnets mainly appear as multiformity annularity which has rutile,hornblende,chlorite and some little ilmenite inside the rings as well as the hornblende and chlorite between the ring and the intercrystalline minerals of garnet.Nearly all the garnet rings are distributed with a great deal of rutiles and are must be in them.The reason to cause the strange phenomena is the initial rock,which is made of high-titanium basic intrusive rock.The lower tectono-corrected depth crystal the ilmenite and made it appear as irregularity agglomerate.A great deal of almandine decomposes the ilmenite,and gives off the iron which turns into the garnet lattice,and the titanium given off becomes rutile during metamorphosing and mineralization.更多还原
