瑞雷波勘探在地下洞穴探测中的应用   总被引：4，自引：0，他引：4  

牛建军  郑作栋 《世界地质》1997,16(2):79-82

利用瑞雷波勘探方法进行地下洞穴探测，在实际处理过程中，对场地所测得的面波频散曲线进行分类、归纳，并利用动力触探曲线对各种特征曲线所反映的地下洞穴情况进行标定，从而确定整个测区洞穴的空间分布规律。  相似文献   

松潘—甘孜造山带中巴西金-矽卡岩矿床成矿热液系统演化的(REE、Sr、O)证据   总被引：2，自引：0，他引：2  

季宏兵  王世杰  李朝阳  文锦明 《矿物学报》1997,(4)

本文通过对巴西典型金-矽卡岩矿床的解剖，探讨了成矿流体来源、组成演化，以及流体和岩石之间的质量转移程度和机理的信息，揭示金成矿过程中成矿流体演化的规律。研究认为，成矿作用两阶段的成矿流体分别为变质流体和大气降水，它们在开放系统中水岩质量比分别为0．02，2．11，并且获得矽卡岩可能是由围岩转向岩体方向的变质流体交代形成的认识。  相似文献

为了使工程地质学在工程建设和防灾减灾方面发挥更大的作用，作者主张在工程地质力学和系统科学指导下发展工程地质力学综合集成（EGMS）。本文主要论述了EGMS形成的基础、相应的方法和技术以及综合集成中的4个关键问题（包括应变体系、优先监测和加固突破口的设计方法，综合地质信息分析系统、时空综合分析方法等）。另外，还扼要地讨论了如何将EGMS用于五强溪水电站船闸边坡的问题。  相似文献   

应用地理信息系统处理地质信息的探讨——以在河北省晚古生代岩相古地理研究中的应用为例     

窦建伟  邵龙义  张鹏飞  武清海  孟逢源 《沉积与特提斯地质》1997,17(5):57-64

本文介绍了ＧＩＳ的基本概念原理，分析了应用ＧＩＳ处理地质信息的可行性和优越性，并以在河北晚古生代岩相古地理研究中的应用为实例，介绍了应用ＧＩＳ处理分析地质信息的一般方法。最后分析了ＧＩＳ处理地质信息方面还存在的一些问题，笔者认为，随着ＧＩＳ技术及其基础学科的不断发展，ＧＩＳ在处理地质信息方面将显示出更大的潜力  相似文献

Looting, collecting, and the destruction of archaeological resources     

Ricardo J. Elia 《Natural Resources Research》1997,6(2):85-98

Archaeological sites, the material remnants of our human past, are finite and nonrenewable cultural resources that are under constant threat from environmental forces, development activities, warfare, vandalism, and looting. Site looting is the destructive removal of archaeological objects to supply the art market. Looting is part of an economic system, the antiquities market, that works to supply the demand of collectors for archaeological objects. The destruction of archaeological resources by looters is an international crisis and threatens to obliterate the world’s cultural heritage and our ability to understand past cultures. The scale and intensity of the looting problem can be estimated by studying the extent of site destruction in countries of origin and by investigating the sources of antiquities held by collectors. Finding a solution to the problem of looting will require a focus on the demand side of the market (i.e., collectors) instead of the traditional focus on the supply side (looters, dealers)  相似文献
