西部大开发中的东西关系问题探讨——以粤、桂两省（区）为例

以粤桂两省区为例，用地理哲学的理论为指导，深入分析了当前与西部大开发战略密切相关的6个东西关系问题：研究结果表明，用地理哲学规律剖析西部大开发战略实施的背景，可以加深对西部地区和大开发战略本质的认识，从而拓宽开发西部的思路，用正确的理论指导西部大开发的实践。     

广西对越边贸口岸的空间分析

广西是我国对越边贸的主要省区，拥有全方位开发的口岸，由于区位，交通条件的差异性，口岸群的空间结构具有明显的层次，并在边贸业迹上有所表现，为了优化广西边贸口岸的空间结构，文中提出了突出重点把凭祥、东兴建成现代化边贸口岸、培育特色口岸经济，加大边贸的开放力度、提高口岸群的整体水平，以及建立新型的边境贸易空间组织－边境贸易开发等对策建议。     

古特提斯造山带在华南两广交界地区的新证据

作者等在两广交界罗定一带新发现了中晚克生代的枕状熔岩和二叠－三叠纪的构造混杂岩，结合区域构造，分析并提出了钦州－岑溪－罗定－云浮构造混杂带的存在。它与全球古特提斯构造域的发育演化联系，故提出了两广交界地区存在古特提斯构造的分支带。     

中国东北现今主导构造

在以遥感图像、地质、地球物理等资料分析东北地区构造骨架的基础上，结合天然地震、地应力测量和现代地壳形变等资料的研究，提出北东向构造是我国东北现今主导构造，并讨论了现代构造应力场及地震发生的构造环境。     

广西佛子冲铅锌（银）矿田岩浆岩的时代及地球化学特征

广西佛子冲铅锌（银）矿田内发育两个岩浆岩系列，即海西期弱碱质Ｓ型花岗岩系和燕山期钙碱质Ⅰ型花岗质火山岩系，两者的地球化学特征差异十分显著。钙碱质岩系由早期至晚期，其岩石特征参数、微量元素及稀土元素表现出规律性变化，反映出同源火山岩浆的演化特征。铅锌（银）成矿作用与钙碱质岩系，尤其是晚期浅成侵入体（次火山岩）密切相关。     

赣东北壳体构造演化与铜(金)多金属成矿系列

赣东北地区是我国重要的铜（金）多金属矿化密集区。自晋宁运动以来该区壳体构造活动复杂而强烈,先后经历过三个不同性质的壳体构造发展阶段。每一阶段中均形成有各自不同性质和不同特点的合矿建造,并形成三套与之相应的铜（金）多金属成矿系列,即元古宙动力变质成矿系列。古生代喷流沉积成矿系列及中新生代火山一次火山成矿系列。     

Shifting of the volcanic fronts during Early to Late Miocene in the Northeast Japan arc

Abstract Recent advanced chronological studies for the Tertiary volcanic rocks from the Northeast (NE) Japan arc revealed three volcanic fronts which differed in temporal and spatial distribution. These fronts were (i) the Matsumae-Shizukuishi-Shiogama line of 22–25 Ma which is obliquely across the Quaternary volcanic front (QVF); (ii) the Tomari-Shiogama line of 13–16 Ma which exists 30–50 km east of the QVF and (iii) a line of 0–8 Ma which is the same as the QVF. The first shifting of the 22–25 Ma line to the 13–16 Ma one was due to the counterclockwise rotation of the NE Japan arc during 20–12 Ma as proposed by Otofuji et al . (1985), and the second shifting of the 13–16 Ma line to the 0–8 Ma line could have contributed to a decrease in the dip of the slab of the Pacific plate which subducted beneath the NE Japan arc during 13–8 Ma.     

大厂锡矿床硅,氧同位素地球化学

本文对大厂锡矿床不同类型石英和岩石进行系统的硅、氧同位素研究表明，各类矿化体中石英的硅同位素组成几乎相同，而且它们又与直接容矿硅质岩的δ30Si值十分接近，但完全不同于矿区侵入岩的有关值。这说明层状矿体中的石英与直接窑矿硅质岩有相同的硅质来源，后期各类脉状矿化过程中的硅质来自容矿硅质岩，而不是花岗岩。层状矿体中荣带状岩石和含冰长石混合样的δ30Si值为-0．3‰±0．2‰，这组负值可能是由冰长石引起的。但冰长石中的硅是由海底热水活动系统还是火山灰尘提供尚待研究。对比发现，本矿区硅质岩δ30Si值与部分深海（洋壳区）、半深海（陆壳区）放射虫硅质岩有关资料相似，但其δ18O值低于全球各类硅质岩，它们可能是在海底热水活动与生物化学作用共同参与下形成的。     

NIZUSE: a deep seismic reflection line in north-eastern Germany

Out of a dense network of seismic reflection lines for hydrocarbon exploration in the North-east German Basin, several lines were recorded to 12 s TWT to obtain information about the structure of the crust and the crust-mantle transition. One of these profiles is presented here. This stretches for 110 km in a NNE direction between Neustrelitz and the island of Usedom. It reaches from the External Variscides in the south across the North German Massif into the Rügen-Pomorze Terrane in the Baltic Sea. Below Cenozoic-Mesozoic-Paleozoic cover with clear reflections down to base Zechstein, the reflectivity varies considerably with depth and also laterally. The Paleozoic and Precambrian sediments and basement are generally void of reflections, but the lower crust and the Moho show strong reflections. To the north the reflectivity decreases, and the Moho depth increases to beyond the bottom of the record section at 12 s. There are no direct indications for deep-reaching faults such as the Trans-European Fault in the north. The North German Massif acted as a ramp towards the Variscan Orogeny, similar to the London-Brabant Massif further west.     

用遥感图像分析中国东北新生代地壳水平运动

从遥感地质角度，结合地质、地貌来研究东北地区新生代地壳水平运动特征、规律。东北新生代地壳水平运动表现为水系变形、山体错移、新构造被错断、地质体错移变形等。呈现出其运动的广泛性、协调性、多期性、继承性和持续性。该区的应力场在新生代期间多次改变，并控制了主要断裂的活动方式。
