1.The control of the deep-seated structural-magmatic process over the metallogenic system around the middle-lower Yangtze River reaches is shown as: (1) the mantle uplift belt is closely related to the general geological background of the metallogenic system; (2) the primitive magma originated from different parts of the mantle uplift belt (mantle ridge or mantle slope) shows differences in style of formation and composition and results in different magmatic series and metallogenic subzones, respectively; (3) the varying depths of structural-magmatic chambers may form a "three-layered structure" (central type, network-like and ring-like) and this is the primary factor that controls the different magmatic series and the concerned cluster of ore deposits; (4) the alkaline basaltic magma derived from the mantle ridge forms high-potassium and calcium alkaline magma and shoshonitic magma due to its altering intensity of AFC process with the lower crustal material, which has something to do with the copper-gold and iron-sulphur metallogenic subsystems, respectively.
深部构造岩浆作用对长江中下游成矿带安徽沿江地区成矿系统的控制表现为：(1)地幔隆起带与成矿系统的总体地质背景的演变密切相关；(2)源于地幔隆起带不同部位(幔脊与幔坡)的原始岩浆，其生成方式和物质组成不尽相同，它们分别产生相应的不同岩浆岩系列和成矿亚带；(3)不同深度的构造岩浆房组成中心式网格式环带式“三层结构”，是控制区内不同岩浆岩系列及有关矿床集中分布的主要因素；(4)源于地幔隆起带脊部的碱性玄武岩浆，由于与下地壳物质发生的AFC作用强度不同，形成了高钾钙碱性岩浆和橄榄安粗岩浆，分别与铜、金成矿亚系统和铁、硫成矿亚系统有关。
2.The authors hold that the joint actions of numerous factors such as the upper mantle uplifted zone (the mantle thinned zone of lithosphere), the upper mantle anomalous area (relatively low-velocity area), the uplifted zone of intracrustal high-conductivity layer, the deep fault (shear zone of lithosphere), the margin of the crust-upper mantle uneven masses, the basement uplifted area reflected by gravity high, the magmatic belt and tectonic intersection reflected by skipped magnetic field, control the distribution of auriferous skarn deposits and copper (associated with gold) skarn deposits.
作者认为，上地幔隆起带（岩石圈地幔减薄带）、上地幔异常区（相对低速区）、壳内高导层隆起带、深断裂（岩石圈剪切带）、地壳上地幔不均匀性块体的边缘、重力高反映的基底隆起区、跳跃磁场反映的岩浆岩带和构造交汇处等诸多因素的共同作用控制著含金夕卡岩矿床和铜伴生金夕卡岩矿床的分布。
3.On the basis of outlining the basic features of CMB, this paper presents systematical summaries of the research results and related problems on the following aspects:the material chemical reactions and forming of D" layer, mass transfer between core and mantle; heat transfer from core to mantle and their contribution to mantle convection; and core-mantle coupling and angular momentum transferring.

4.A comparison of the upper mantle model of this study with the West Europe upper mantle model K8, Northwestern Eurasia upper mantle S8 and Tibet upper mantle model QX8 indicates that the shape of the P velocity profile of this study is similar to these tectonic regions through the transition region (300-700 km), but there are differences in the absolute depths to the discontinuities.
通过与欧洲西部上地幔模型K8,欧洲西北部上地幔模型S8和西藏地区上地幔模型QX8比较,我们发现各个构造区P波速度的过渡区是一致,但间断面的绝对深度不一样.
5.In the subduction zones, primary adakite melts during magmatic ascent and reaction with mantle peridotite will gain mantle components such as MgO, CaO, Cr and Ni but will lose Na?2O, SiO?2 and perhaps K?2O to the mantle, leading to Na-rich mantle metasomatism.
在俯冲带,大洋板片熔融产生的熔体(埃达克熔体)上升并与地幔橄榄岩发生反应,原始的埃达克熔体获得MgO、Cr及Ni等地幔组分,但其Na2O和SiO2等通过反应进入地幔,导致地幔交代作用。
6.We take ρ= 5500kg/m~3 as the average density of the mantle and μ=10~(21)Pa·s as the average viscosity of the upper mantle and calculate the convection patterns of the mantle with different viscous rations of 1, 10, 100 and 1000 between the lower and upper mantle, respectively.

7.This work introduces main methods to study oxygen fugacity of the mantle, discusses temporal and spatial variations of oxygen fugacity of the mantle, and concludes that the Earth mantle becomes more and more oxidative with the mantle evolution, and more and more reductive with depth increasing.
定性探讨了地幔氧逸度的时空分布规律 ,获得了地幔随时间的推移变得愈来愈氧化 ,随深度的增加变得愈来愈还原 ,以及在横向上不同大地构造部位的地幔区域具有不同的氧逸度等诸多结论。 结合目前人们对地幔物质组成、性质、状态、运动过程及地球的起源与演化历史等的认识 ,初步提出了地幔不同圈层氧逸度的约束机制。
8.Based on research on regional geology,distributions and compositions of Mesozoic and Cenozoic magmatic rocks,and mantle plume in Gejiu district,Yunnan Province,the paper suggested the granite in the study area is neither I-type granite nor S-type granite but the mixed-melting type granite of Crust-Mantle. It is reasonable that tin-ploymetallic deposits might have been formed by the ore-forming fluids of post-magma hydrothermal activity with main metallogenic materials derived from the Earth mantle.

9.The comparison of Cenozoic basalts and their mantle xenoliths from both sides of the Taihangshan gravity lineament reveals that: (1) Cenozoic basalts from western and eastern North China display opposite temporal trends, suggesting lithospheric thinning in western North China during the Cenozoic and lithospheric thickening in eastern North China; (2) The lithospheric mantle in the west is mostly Late-Archean to Proterozoic in age, whereas that in the east has a modern age with minor Proterozoic age; (3) The crust mantle transition in the west is considerably thicker than in the east, probably due to different extents of magmatic underplating.
摘要通过对比华北太行山重力梯度带两侧新生代玄武岩及其中幔源包体的成分，发现：(l)华北东、西部新生代玄武岩具有相反的演化趋势，说明新生代以来西部岩石圈逐渐减薄，而东部岩石圈逐渐加厚；(2)西部岩石圈地幔组成相对复杂，年龄多为晚太古代－元古代；而东部岩石圈地幔组成相对单一，年龄多为现代值，少数为元古代；(3)西部壳幔过渡带较厚而东部较薄，反映两地不同的岩浆底侵作用程度。
