遥感解译工作在区域地质调查中发挥了不可忽视的作用,通过对内蒙古1∶5万六户等四幅进行矿产调查,对该地区地表覆盖严重的地区进行了地质解译、图像处理和多波段数据采集分析。由于调查区覆盖严重、可解译性差,因此研究除注重技术方法的先进性,还注重与野外调查相配合。在研究初期与验证阶段都进行了大量的野外调查工作,在很大程度上提高了解译目标的针对性和解译成果的准确性。该次研究成功区分地层、侵入岩、构造的相互关系。经野外验证,在地质体展布与断裂解译方面较为准确,达到了较好的地质效果,大大提高了区域地质调查和编图的速度及质量,成为该区域地质工作的重要方法手段。 相似文献

基础性战略性地质调查工作是一项服务于国家和全社会经济发展的公益性地质工作。地质调查是指对某地区的岩石、地层、构造、矿产、水文地质、地貌等地质情况进行的调查研究工作。野外地质调查中,我们进行的地质调查会辅助部分山地工程来开展,在生活上,需要野外驻地和当地群众对我们的支持,也需要当地群众及公安派出所予以一定的安全保证,我们在尊重当地民风民俗以及维护当地群众的合法权益的同时,需要一个良好的地质调查外部环境,这对顺利开展工作和提高工作效率非常重要。 相似文献

地质调查剖面图的机助设计制图 总被引：1，自引：0，他引：1
地质模型和数学模型的建立是解决问题的关键,从而使“计算机辅助野外地质调查系统”更便利、高效地适用于野外地质工作。实测剖面图是地质调查中,经常用到的技术方法和手段,以利对地质现象更清楚的认识。三联点构造描述方法及剖面图制作,是计算机辅助地质调查中十分重要的研究内容。本文探讨了三联点构造野外描述的内容及顺序、构造级别的划分等。对此选择VisualC++为开发工具,设汁了实测剖面图子系统。分为数据录入模块、图形绘制模块及成果数据管理模块。同时介绍了实测剖面图的数据结构及图层划分,提出了实现数据录人模块和图形模块的方法。 相似文献

The ability of cell to modulate the fluidity of plasma membrane was crucial to the survival of microorganism at low temperature. Plasma membrane proteins, fatty acids and carotenoids profiles of Antarctic psychrophilc yeast Rhodotorula sp. NJ298 were investigated at -3 ℃, 0 ℃ and 8 ℃. The results showed that plasma membrane protein content was greater at -3 ℃ than that at 8 ℃, and a unique membrane polypeptide composition with an apparent molecular mass of 94.7 kDa was newly synthesized with SDS-PAGE analysis; GC analysis showed that the main changes of fatty acids were the percentage of unsaturated fatty acids (C18∶ 1 and C18∶ 2) and shorter chain saturated fatty acid (C10∶ 0) increased along with the decrease of the culture temperature from 8 ℃ to -3 ℃; HPLC analysis indicated that astaxanthin was the major functional carotenoids of the plasma membrane, percentage of which increased from 54.6±1.5% at 8 ℃ to 81.9±2.1% at -3 ℃. However the fluidity of plasma membrane which was determined by measuring fluorescence anisotropy was similar at -3 ℃, 0 ℃ and 8 ℃. Hence these changes in plasma membrane's characteristics were involved in the cellular cold-adaptation by which NJ298 could maintain normal plasma membrane fluidity at near-freezing temperature. 相似文献

As an important component of the cryosphere,sea ice is very sensitive to the climate change.The study of the sea ice physics needs accurate sea ice thickness.This paper presents an electromagnetic-induction(EM) technique which can be used to measure the sea ice thickness distribution efficiently,and the successful application in Bothnian Bay.Based on the electromagnetic field theory and the electrical properties of sea ice and seawater,EM technique can detect the distance between the instrument and the ice/water interface accurately,than the sea ice thickness is obtained.Contrastive analysis of the apparent conductivity data obtained by EM and the value of drill-hole at same positions allows a construction of a transformable formula of the apparent conductivity to sea ice thickness.The verification of the sea ice thickness calculated by this formula indicates that EM technique is able to get reliable sea ice thickness with average relative error of only 12%.The statistic of all ice thickness profiles shows that the level ice distribution in Bothnian Bay was 0.4-0.6 m. 相似文献

The GRV 024516 and GRV 024517 meteorite samples collected from Grove Montains,Antactica are ureilite and H5 ordinary chondrite,respectively.Based on the study of mineralogy-petrology,the cosmic-ray exposure ages and gas retention ages of these two meteorites were determinated and calculated.Their cosmic-ray exposure ages are 33.3 Ma,51.7 Ma,and gas retention ages are 1936.8 Ma and 3720 Ma,respectively.The ureilite contains diamond,graphite and amorphous C,which are mainly carrier of noble gases indicating obviously shock metamorphism effects,which induced 40Ar partial loss.The H5 chondrite indicates thermal metamorphism of parent body,its gas retention age fall the range between 3220 Ma and 4510 Ma of the least shocked H5 chondrites 相似文献
