目前,物化探找矿方法得到了广泛的应用,特别是在化探异常远景区所进行的异常验证阶段,利用物化探找矿方法在异常查证上相互验证、指导找矿方向起到了重要作用。化探方法对于异常源只能是确定异常体的分布范围,为下一步找矿工作缩小了工作靶区,但该方法确定不了引起异常地质体的实际位置。而物探方法则不然,它所反映的是异常体的物理特征, 相似文献

大兴安岭地区1：5万航空物探测量项目,是黑龙江省政府和国土资源部合作开展的一个大型基础调查项目。此项目的开展,可以进一步丰富该地区地质找矿资料,加快其找矿步伐,通过发现、检查一批航空物探异常,为工作区提供有利成矿区段和找矿靶区。2010年的地面查证中,在编号为45的航磁异常查证区内,发现了较好的物化探异常,工程验证中发现了2条钼矿（矿化）体,为下一步工作提供了找矿靶区。下面把45号航磁异常的查证情况介绍如下。 相似文献

Based on the hydrographic data in austral summer during the 22nd Antarctic Expedition of China(2005/2006),some features can be found about the northern margin of Emery ice shelf as follows.The heat content in the surface layer(0-50 m) at the eastern end and the western end of the ice-shelf margin is much higher than that at the middle.The upper mixing-layer depth and the seasonal thermocline depth at the middle of the ice-shelf northern margin are much shallower than those at the both ends.However there is much less difference between the middle and the ends in the bottom layer.The remote sensing photos show that the inhomogeneity in the surface-layer water is closely related to the spatial distribution of the floes and polynia in the area. 相似文献

Phylogenetic analysis based on 16S rDNA of 8 strains of cultivable bacteria isolated from Arctic sea-ice was studied.The results showed that strain BJ1 belonged to genus Planococcus,which was a genus of low mole percent G C gram-positive bacteria;strain BJ6 belonged to genus Burkholderia of β-proteobacteria and the rest 6 strain all belonged to γ-proteobacteria,of which strain BJ8 was a species of Pseudoalteromonas,strain BJ2-BJ5 and BJ7 were members of genus Psychrobacter.Phylogenetic analysis also indicated that bacteria of genus Psychrobacter of the isolates formed a relatively independent phylogenetic cluster in comparison with other bacteria belonged to genus Psychrobacter. 相似文献

Using the NCEP/NCAR reanalysis monthly 500 hPa height data on a 2.5 latitude-longitude grid and 1°×1° sea ice data,the polar vortex area,intensity index and arctic sea ice area index are calculated respectively,and the meridional distribution,period variation and the abrupts in the long range trend are analyzed to study their relationship.The results show that the meridional distribution of sea ice and polar vortex h-ave distinctive difference,the relative positions of them are different in the eastern and western hemispheres,and exept they have periods of 4 months,quasi half year,quasi year,4-5 years and 10 years commonly,and each of them has its own respective variation as well.The sea ice area is decreasing apparently since 1980's,so is the polar vortex area,but their abrupt changge time are different totally.The area of sea ice and polar vortex has prominent positive correlation,but the relationship of sea ice intensity,polar vortex intensity,polar vortex area is complicated. 相似文献
