卡乌留克塔格C-12磁异常位于兴地大断裂南侧,航磁为低缓异常,地磁异常则极值较大.通过地面高精度磁法工作,确定了航磁异常在地面的具体位置及形态、范围及变化特征.根据磁异常的推断解释,C-12异常为超基性岩体引起.由此可见,磁法测量对寻找基性、超基性含铁磷岩体具有重要的意义.  相似文献

OpenStreetMap (OSM) tags were used to produce a global Open Land Cover (OLC) product with fractional data gaps available at osmlanduse.org. Data gaps in the global OLC map were filled for a case study in Heidelberg, Germany using free remote sensing data, which resulted in a land cover (LC) prototype with complete coverage in this area. Sixty tags in the OSM were used to allocate a Corine Land Cover (CLC) level 2 land use classification to 91.8% of the study area, and the remaining gaps were filled with remote sensing data. For this case study, complete are coverage OLC overall accuracy was estimated 87%, which performed better than the CLC product (81% overall accuracy) of 2012. Spatial thematic overlap for the two products was 84%. OLC was in large parts found to be more detailed than CLC, particularly when LC patterns were heterogeneous, and outperformed CLC in the classification of 12 of the 14 classes. Our OLC product represented data created in different periods; 53% of the area was 2011–2016, and 46% of the area was representative of 2016–2017.  相似文献

通过对卡乌留克塔格矿区自然地理特征及地质特征的分析,认为矿区的地下水主要为第四系孔隙水和基岩裂隙水,其补给来源一是降雨,二是地表水,三是山区地下暗流。矿山开采后对水资源环境的影响主要会引起地面沉陷,地下水位下降。应采取先探后采.边采边探的生产安全措施。  相似文献

通过对且干布拉克地区西山布拉克组泥质岩岩石学、地球化学特征的研究,探讨其物源特征、风化作用以及沉积盆地的构造环境。且干布拉克大坂剖面泥质岩Al_2O_3/TiO_2、Th/Sc、(Gd/Yb)_N、(Eu/Eu*)_N、ICV、CIA均值分别为24、0.9、1.1、0.6、1.2、70,莫合尔山剖面泥质岩Al_2O_3/TiO_2、Th/Sc、(Gd/Yb)_N、(Eu/Eu*)_N、ICV、CIA均值分别为10.5、0.2、3.5、1.01、2.8、75。这些特征表明,研究区泥质岩为第一次沉积的沉积物,源区母岩主要以岩浆岩为主。且干布拉克大坂剖面泥质岩的源区母岩主要以南部的花岗岩等长英质岩浆岩为主,沉积于陆内较稳定的构造环境;莫合尔山剖面泥质岩的源区母岩主要以北部玄武岩等中基性岩浆岩为主,沉积于陆内火山岩隆起的构造环境。在诺丁尼亚超大陆裂解的大构造背景下,早寒武世早期莫合尔山的裂解作用比且干布拉克大坂更为强烈。CIA值表明且干布拉克地区泥质岩物源区母岩经历了中等程度的化学风化作用,沉积物沉积时气候较温暖、湿润,早寒武世早期位于30°S左右的低纬度地区。且干布拉克大坂剖面的含钒炭质硅质页岩、莫合尔山剖面的铁质磷质岩的元素地球化学特征暗示了磷、钒等成矿元素与可能来自于震旦纪和寒武纪的中基性火山岩。  相似文献

With the widespread use of tag clouds, multiple map-based variations have been proposed. Like standard tag clouds (also called word clouds), these ‘tag maps’ all share the basic strategy of displaying words within a ‘geographic space’ and scaling the word size to depict frequency (or importance) of those words within some dataset. While some tag maps simply plot a standard tag cloud on top of a map, the subset of tag maps we focus on here are those in which the collection of words are displayed within bounded geographic regions (often of irregular shape) that the words are relevant for. For this form of tag map, map scale and polygon shape add constraints to word size and position that have not been considered in most prior approaches to tag map word layout. In this paper, we present a layout strategy for tag map generation that includes consideration of the shape and size of the geographical regions acting as containers for the tags. The method introduced here uses a triangulated irregular network (TIN) to subdivide the geographical region into many triangle subareas, with the centroid of each triangle being a potential location to centre a tag on. All the triangles are sorted by their area and all the tags are sorted by their weight value (e.g. frequency, importance or popularity). Positioning of tags is undertaken sequentially from most important (or frequent or popular) with potential locations being the TIN triangle centroids (tried from largest to smallest triangle). After each tag placement, the TIN is recalculated to integrate the tag centroid and bounding corners into the TIN creation. The limited whitespace in the geographical region, at any specific scale, is used fully by dynamically adjusting the font size along with the number and the direction of tags. The method can be applied to add tags within geographic polygons that are convex, concave and other more complex regions containing holes or islands.  相似文献
