Geological Characteristics of Xiarulin Ilmenite Deposit in Yishui County in Shandong Province

Xiarulin ilmenite deposit locates in east part of Gongdanshan uplift in Yishu fault belt, and west part of Fulaishan-Baifenzi fault belt. Neoarchean titaniforous magnetite amphibolites whic intruded into Neoarchean Taishan group are its major ore-bearing rock. It developed as pod and belt type in Taishan group , or trapped by medium-coarse low gneiss mozonitic granites in Aolaishan formation of Mesozoic Lvliang group. It has the same occurrence with Neoarchean metamorphic strata. 5 orebodies have been circled with the length of 204～1000m and the width of 14～140m. TFe content is 15%～16%, average content is 15.55%, and reach 21.84% maximumly; TiO_2 content is 5%～8%, average is 6.54%, and can reach 10.13% maximumly. The content of TiO_2 has direct correlation with TFe content variation.
