A good many mico-landblock of the early Neoproterozoic-Cambrian volcanic rock that distribute in the Tianshan orogenic belt and on its both sides, and the Carboniferous-Permian volcanic rocks that widely distribute in the Tianshan and adjacent regions are selected for subject investigating in this paper. Renewing the ocean-land format and ocean-land conversion process of Tianshan orogenic belt in the Paleozoic is the masterstroke for this paper. On the basis of detailed field investigation, many subjects, such asregional lithology、geochemistry、structural geology、volcanic sedimentology geology、sotope geochronology and synthesis analysis study of geophysics data, are adopted as instrumentality in the paper, this study lays emphasis on the formation, evolution and dynamics of early Neoproterozoic-Cambrian and Carboniferous-Permian volcanic rock in the Tianshan and its adjacent regions to find out Carboniferous-Permian volcanic rock property, eruptive sequence, time and space distribution characteristics, to resume and reconstruct evolution process of Carboniferous-Permian volcanic rock, and to explore connection of magmatism process and lithosphere stretching action of neopaleozoic ocean-land transformation in the Tianshan region.

本文选择分布于天山及其两侧的诸多微陆块上新元古代—早寒武世火山岩和天山地区广泛发育的石炭纪—早二叠世火山岩为研究对象，以恢复重建天山造山带古生代洋陆格局和洋陆转换过程为主线，在详细的野外工作基础上，综合运用区域岩石学、地球化学、构造地质学、火山沉积学、同位素地质年代学、区域地球物理资料综合分析研究等多学科手段，重点研究天山及其邻区新元代—早寒武世和石炭—二迭纪火山岩系的形成演化及其动力学，查明天山石炭纪火山岩系的性质、喷发序列、时空分布特点，恢复重建其形成演化过程，探索天山地区晚古生代洋陆转换过程中火山岩浆作用与岩石圈拉伸作用的关系。

The parental magma of the mafic dykes is probably derived from EMI, DM-PREMA and subcontinental mantle sources.

同位素和微量元素研究显示，岩浆源区主要与富集Ⅰ型地幔，弱亏损的常规地幔以及陆下岩石圈地幔有关。

Its main aims include:(1) understanding the magmatic processes of the volcanic rocks and their petrogeneses;(2) discussing the possible enrichment processes induced by subduction of continental slab;(3) providing geochemical constraints on the nature of lithosphere (including the subcontinental lithospheric mantle and lower crust) of the different tectonic units confined by the major faults across the belt; and (4) geochemical comparison of the lithosphere in an attempt to define the possible boundary between the North China and Yangtze Blocks during Mesozoic time.

中文摘要：项目开展了穿越苏鲁造山带南北向晚中生代火山岩及相关火成岩的廊带剖面(包括苏鲁带的胶东、青岛、滁州和下扬子地区的溧水盆地)的地球化学研究，理解各区块晚中生代岩浆作用过程和成因，探索大陆俯冲作用的地幔富集过程以认知各主要断裂围限地区的岩石圈性质；通过对比不同地区的岩石圈性质来限定苏鲁地区华北与扬子陆块的中生代碰撞边界。

Information from the Apollo missions has led some investigators to favor a warm ancient Moon (Smith et al., 1970; Wood,1972). This idea has been most recently amplified by Wood (1975) and Walker et al.(1975) who suggest that the petrology of the ancient anorthositic lunar crust can be explained as having resulted from crystal fractionation and gravitational separation in a well-stirred global subcrustal magma chamber referred to by Wood (1975) as a magma ocean.

根据阿波罗任务的信息，部分调研者对早期月球是温暖熔融的青睐有加（参见1970年史密斯团队报告稿和1972的伍德报告）。1975年，伍德和沃克团队进一步加强了这个观点，他们推测：古老月球曾经是熔融的，充分对流、搅拌的全球性岩浆海洋中的重力分离和结晶分异过程能够解释辉长岩月壳的来历。

Also, Mt. Fuji has fresher magma than do volcanoes in most subduction zones.

同时，它里面的岩浆比大部分潜没区域的火山都更新鲜。

Metallogenic conditions are analyzed from the magmatism of REE bearing syenite,hydrothermal activity and fracture activity.

从富含稀土的正长岩岩浆活动、浅成热液作用和断裂构造分析了矿床成矿条件。

Bengge syenite s has been always regarded as the product of alkaline magma activity controlled by the strike-slip structures caused by collision between Yindia and Euroasia.

长期以来，甭哥正长岩体被认为是印度—欧亚板块碰撞引起的走滑剪切构造所控制的碱性岩浆活动的产物。

It shows that the magma forming the syenite in the Luzong basin was derived from a deep source, most likely resulting from the partial melting of an alkali basalts along the deep fault, and obviously contaminated by continental crust material.

反映了庐枞盆地正长岩类成岩物质来源较深，是来自富集地幔的碱性玄武岩浆在沿深大断裂上升侵位过程中，受到部分陆壳物质的混染而成。
