第四纪冰川和冰川地质遗迹的研究,是研究第四纪全球气候变化的重要课题之一.中国第四纪冰川地质遗迹分布很广,类型多.最北的大兴安岭、南部的广西大明山、东部的长白山和台湾玉山、最西的喀喇昆仑山第四纪冰川地质遗迹均有分布,是世界上低纬度地区山岳冰川发育最广泛的国家.笔者等在前人研究的基础上,系统阐述我国第四纪冰川地质遗迹分布概况,结合开展的全国重要地质遗迹调查,以地质遗迹调查规范为基础,系统开展第四纪冰川地质遗迹调查方法研究.根据冰川在运动过程中对地面的侵蚀、冰碛物的搬运和堆积等不同的地质作用阶段,总结我国第四纪冰川地质遗迹调查方法体系,为开展同类地质遗迹调查提供方法指导.

阿尔及利亚金矿主要分布于南部地区Hoggar地盾.受泛非运动影响,Hoggar地盾与西非克拉通挤压碰撞,区内金矿沿南北向断裂带分布.Tin-Zakri金矿位于Hoggar地盾近南北向Tiririnienne成矿带上,受区内北西向主构造控制.目前发现与矿化有关的矿化蚀变带30条,其中规模较大的有2条（27、30号脉）,矿体赋存在片理化岩带内,呈北西向或近南北向脉状展布,以石英脉的形式断续分布在韧性剪切带中.围岩蚀变特征明显,绢云母化为金矿的直接找矿标志,绿泥石化片理化带是金矿找矿的重要线索.

国家地质公园是国家重要地质遗迹的自然保护区.国家地质公园数据是基础科学数据资源之一.中国地质科学院通过收集国家地质公园原始申报资料,汇集了我国182个国家地质公园的相关地质数据集.在此基础上建立了基于ArcGIS的国家地质公园空间数据库.并采用ArcReader工具制作了可脱离ARCGIS系统的、面向各类用户分发的、便于在各类电脑(含便携式)安装的的国家地质公园数据产品.本文介绍了研究工作方法与流程,诣在能对地质领域数据资源的共享服务提供借鉴.

呵叻盆地与兰坪—思茅盆地同处藏滇印支褶皱系,成矿时代相同,析盐矿物组合类似.文章对比两者钾盐产出特征、成矿地质背景和成盐演化,分析两者成矿条件.建议在区域钾盐找矿工作中,应充分重视断陷盐盆地中有深卤补给的可能性,以及中、新生代碎屑岩系的盐盆地,如果成盐盆地规模较大,卤源补给丰富,古气候条件适宜,即使为陆源碎屑岩系,也仍有可能形成大型钾盐矿床.

Apart from common ripple marks,mudcracks, there are miscellaneous traces on the bedding planes of the Mezoproterozoic sandstones in Licheng Geopark, Shanxi Province, such as lithic earthworm,arcuate traces, starry traces, whose forming processes can hardly be understood on the basis of mechanics. Having a preliminary analysis, it is considered that the meander burrow or Nereites, crossed-S-liked traces, 8-liked traces should be trace fossils formed by worms or microbially induced sedimentary structures (MISS); the starry traces, whose single trace is short line, commonly thins out on the two ends, and 3 single short lines composed a trilete, should be similar to reported ice-wedge traces. It is more valuable that gradually transitional characteristics can be found between these traces, which prompt that we should comprehensively and systematically study the origin of these traces.

Large glacial sheets in the Qinghai-Tibet plateau have an important effect on both Asian and global climate. There is much interest in the timing and duration of the Quaternary glacial in the plateau. Using cosmogenic determinations we have obtained the first in-situ morainal exposure ages from the glacial moraine in the Tanggula mountain and Litang. The three kinds of exposure ages from 10Be, 26Al, and 21Ne are similar. According to our dating, there were two glaciations, one formed between 16-80 ka B.P., and the other between 160-180 ka B.P.
