发展中的中国煤田地质学

中国的煤和煤田地质特征具有鲜明的地域特色和独特的地质问题。煤炭是中国主要的一次能源。本文概要评述了近年来我国煤田地质学科的显著进展，认为未来的发展将取决于，引入新理论、新方法和广泛应用高新技术，强化与其他一些地学分支的交叉和渗透，今后将更突出研究煤的地球化学、支撑洁净煤技术和煤基材料利用技术的地质基础、煤层气，和高产、高效、安全开采煤炭生产的地质保障体系。     

Mapgis在地质学中的应用

简要讨论了Mapgis的主要功能，重点阐述了Mapgis的地质制图技术、空间分析技术以及二次开发能力在地质学领域中的应用，并举例论述之。Mapgis的地质制图技术将纷繁复杂的传统地质制图过程简化，而且美观精确；空间分析技术可以将矢量数据和栅格数据综合制作出各种图形和图象文件，方便分析；地质工作者也可以运用Mapgis的二次开发能力来开发面向特定领域的系统。     

APPLICATION OF SOME MECHANICAL CONCEPTS TO STRUCTURAL GEOLOGY

This paper discusses some mechanical concepts that have been largely applied to structural geology and tectonics, and addresses the problems and misunderstandings in use of these mechanical terms. The purpose is to stimulate the interests for structural geologists in using the mechanical principles and methods correctly to solve the geodynamic problems.     

Regional Fault Systems of Qaidam Basin and Adjacent Orogenic Belts

The purpose of this paper is to analyze the regional fault systems of Qaidam basin and ad-jacent orogenic belts. Field investigation and seismic interpretation indicate that five regional fault sys-tans occurred in the Qaidam and adjacent nment.qin belts, controlling the development and evolution of the Qaidam basin. These fault systems are: (1)north Qaidam-Qilian Mountain fault system; (2) south Qaidam-East Kunhm Mountain fault system;（3）Altun strike-slip fault system; (4) Elashan strike-slip fault system, and (5) Gansen-Xiaochaidan fault system. It is indicated that the fault systems controlled the orientation of the Qaidam basin, the formation and distribution of secondary faults within the basin,the migration of depocenters and the distribution of hydrocarbon accmnulation belt.     

Copper-Polymetal Metallogenic Series and Prospecting Perspective of Eastern Section of Gangdise

Geological, geophysical, geochemical and remote sensing comprehensive studies show that big ore-prospecting potentiality is contained in the eastern section of the Gangdise Mountains, Tibet.There are various mineralization types with dominant types of porphyry and exhalation. According to their relations with tectonic evolution, they are divided into four kinds of metallogenic series as follows:magnmtic type (Cr, Pt, Cu, Ni) and exhalation type (Cu, Pb, Zn, Ag) ore deposit series related to Neo-Tethys oceanic crust subduction action (125-96 Ma); epithermai type (Au, Ag, Pb, Zn, Sb), altered fractured rock type (Cu, Mo) and skarn rock type (Cu) ore deposit series related to arc-continental collision; porphyry type (Cu, Mo), cryptoexplosion breccia type (Cu, Au, Pb, Zn), shear zone type (Au, Ag, Sb) and skarn rock type (Cu, Fe) ore deposit series with relation to post-orogenic extensional strike-slip. From subductive complex to the north, zoning appears to be crystallization differentiation type (segregation type)-shear zone type (altered rock type)-skarn rock type, epithermai type-porphyry type-porphyry type and exhalation type-exhalation type-hydrothermai filling-replacement type.The ore deposit is characterized by multi-places from the same source, parity and multi-stage, hypabyssal rock from the deep source and poly genetic compound as a whole.

地质学应用于生态系统研究中的两个方法

生态系统的研究是国土资源管理的基础，要想更好地理解生态系统，需要把地质学结合到这一系统中，尽管地质学所做的工作在整个系统中是很有限的，但他们却为生态系统的研究提供了大量的信息，这一点对国土资源管理者和相关科学家是很有价值的。本文提出了两个方法，旨在推动将地质学应用于生态系统的研究。这两个方法是：第一，生态系统与地质结合模型，它主要是以计算机数据库的形式来体现地球物理化学性质怀生物圈之间的关系；第二
