秦岭东段金红石矿床分为区域变质、岩浆、热液、风化及沉积五大成因类型。正变质型矿床，常量元素与钙碱性—碱性、基性岩浆岩接近，ＴｉＯ２与ＳｉＯ２呈负相关；稀土元素分布模式由轻稀土富集型渐变为亏损型。副变质型矿床，常量元素与粘土岩接近，ＴｉＯ２与ＳｉＯ２、ΣＲＥＥ等呈正相关；与ＣａＯ、ＭｇＯ等呈负相关。岩浆型矿床，常量元素与超基性岩接近，ＴｉＯ２与Ａｌ２Ｏ３、（Ｌａ／Ｌｕ）Ｎ等呈正相关。热液脉型矿床稀土元素分布模式与母矿床相同。矿床沿深大断裂分布，均位于变质岩区。成矿时代为晚元古代、泥盆纪及第四纪。正变质型矿床一般共生有风化、沉积及热液脉型矿床。成矿机制主要为扬子板块向北两次较大规模的俯冲所致。 The eastern part of Qinling rutile deposit is divided into regional metamorphism, magma, hydrothermal, weathering and sedimentary five major genetic types. In the metamorphic deposits, the major elements are close to the calc-alkaline-alkaline and basic magmatic rocks, while the TiO2 and SiO2 are negatively correlated. The REE patterns change from light rare earth enrichment to depletion. Parain metamorphic deposits, the major elements and clay rocks close to, TiO2 and SiO2, ΣREE and other positive correlation; and CaO, MgO was negatively correlated. In the magmatic deposits, the major elements are close to the ultrabasic rocks, and TiO2 and Al2O3, (La / Lu) N are positively correlated. The pattern of REE distribution in the hydrothermal veins is the same as that of the parent ore deposit. Deposits along the deep fault distribution, are located in the metamorphic rock area. The mineralization age is Late Proterozoic, Devonian and Quaternary. Metamorphic deposits are commonly associated with weathering, sedimentary and hydrothermal vein type deposits. The ore-forming mechanism is mainly caused by the subduction of the Yangtze plate northwards twice larger scale.
