The alkali-rich intrusive rocks are mainly consisted of alkalic rocks and alkalic granites, also include the alkali feldspar granites. The latter two can be named as A-type granites. The mineralization potentiality of the alkali-rich intrusives is as well as that of the S-type and I-type granitoids. The alkali-rich intrusives are generally large in scale. They usually show as linear distribution and are controlled by the regional faults, and occur in the rift, graben andupwarped belt of mantle under tensional...

They usually show as linear distribution and are controlled by the regional faults, and occur in the rift, graben andupwarped belt of mantle under tensional environment. The S-Type. I-type and A-type granites in the same orogenic cycle have their temporal evolution relationship. The S-type →I-type →A-type spatially are evolved from the internal part of continent to the active belt of continental margin.

Geochemical characteristics of Sr,Nd and Pb isotopes in Late Paleozoic-Mesozoic granitoids from Northern Qinling belt show that granitoid batholiths with lower ratios of radiogenic lead isotopes are anatectic products of mixture of metabasalts and metasediments from the basement of the Southern Qinling belt,due to subduction of southern Qinling basement beneath the northern Qinling during continent-continent collision.Innate or subautochthonous granitoids intruding into the Danfeng Group were produced via anatexis...

Geochemical characteristics of Sr,Nd and Pb isotopes in Late Paleozoic-Mesozoic granitoids from Northern Qinling belt show that granitoid batholiths with lower ratios of radiogenic lead isotopes are anatectic products of mixture of metabasalts and metasediments from the basement of the Southern Qinling belt,due to subduction of southern Qinling basement beneath the northern Qinling during continent-continent collision.Innate or subautochthonous granitoids intruding into the Danfeng Group were produced via anatexis and metasomatism of related metavolcanics and metasediments in Danfeng Group under high temperature and pressure in response to the collision.The granitoids can be classified into S-and I-types according ε Nd (t) , ε Nd (t) and T DM .S-type and I-type granitoids may coexist in a multiple batholith.The metabasalts were involved in formation of the two types of granitoids.I-thpe granitoids anre characterized by higher ε Nd (t) and lower T DM compared to S-type granitoids.Because of mixing,the Nd model ages of these granitoids might not represent real crust-mantle separation event.From Neoproterozoic to Mesozoic, ε Nd (t) and T DM of I-type granitoids showed decreasing trend,which reflects decreasing age of fractionation event of metabasalts; ε Nd (t) increases and T DM decreases for S-type granitoids,which indicates increasing involvement of metasediments and suggests stronger magmatism during collision.

北秦岭晚古生代—晚中生代花岗岩类的Nd,Sr同位素研究表明:具低放射成因Pb同位素组成的花岗质岩基主要是南秦岭基底变质岩深熔的产物;而具高放射成因Pb同位素组成的原地、半原地型花岗岩类是北秦岭丹凤群有关岩石深熔和交代作用形成的产物.它们都可分为I型和S型,并可同时共存,岩浆源区中都有基性岩石物质的加入,其区别是基性岩类物质对I型花岗岩类的贡献分数较大,具有较小的亏损地幔模式年龄;由于岩浆源区中不同物质组成的混合,花岗岩类的亏损地幔模式年龄并不代表真实的壳幔分异事件的年龄.从新元古代到晚中生代,I型花岗岩类的d(t)和TDM具逐渐变小的趋势,反映了地壳中基性岩石物质发生深熔作用的时间逐渐变晚,而S型花岗岩类的d(t)增大,TDM变小,反映了基性岩石物质加入比例的增大,暗示着碰撞作用阶段具更加强烈的岩浆作用
