近年来,航空物探项目主要是使用Oasis montaj软件完成数据处理工作,最终提交的成果图件采用MapGIS地理信息系统软件绘制。由于两种软件系统采用的数据格式及兼容性不尽相同,因此采用Visual Basic编程语言编制专用程序,实现两种软件系统数据格式的接口,同时解决MapGIS中剖面平面图的绘制问题。这一问题的解决既发挥了Oasis montaj软件强大的数据处理功能,又充分利用MapGIS软件成熟的绘图功能,同时在项目实施过程中大大提高了数据处理和成果图件绘制的效率,取得了较好的应用效果。 相似文献

Surfer软件具有强大的绘图功能,其自带的Scripter语言又提供了有效编程工具。通过对Surfer Automation技术的分析,以及对VB与Automation语言之间兼容性的研究,利用Visual Basic编程进行化探数据处理,求取化探异常,并结合Surfer Automation技术进行化探异常图的批量自动化绘制。尤其在对数据量较大时,利用该技术进行处理,能提高工作效率。 相似文献

Surfer与MapGIS图件相互转换的几个问题 总被引:4,自引:1,他引:3
随着计算机技术在地质与地球物理工作中的广泛应用,计算机绘图也显得越发重要。为了提高制图质量和效率,在实际工作中经常需要结合使用几种软件。笔者从地质绘图的角度出发,阐述了Surfer与MapGIS的一些基本特点及其在地质领域中的应用,由此引出Surfer与MapGIS转换的必要,详述了Surfer中srf图形与MapGIS格式图件之间相互转换的基本方法及步骤,着重讨论了在转换过程中需要注意的问题,并提出了相应的解决方法。 相似文献

铀矿勘查中,实施地表探矿工程来揭示区内地质及矿化现象是一个行之有效且常用的方法,其矿化成果信息主要由放射性测量成果图件展现,目前主要靠手工素描完成,但存在费时且图件不美观等问题。因此,笔者提出了自动化成图的构想,开发了一款辅助软件来对放射性测量数据进行数据处理,将多参数坐标转换为标准坐标格式,支持Surfer软件数据网格化处理和Mapgis软件输出成果图件,实现自动化成图。经大量地表工程验证,证实辅助软件输出数据准确、可靠,通过Surfer、Mapgis软件实现了放射性测量数据自动化成图。此方法可取代传统手工素描绘图和Mapgis软件矢量化成图等耗时的步骤,将为放射性编录工作带来极大便利,进一步提升成果图件的标准化,提高物探编录的工作效率。 相似文献

Pant-y-ffynnon Quarry in South Wales yielded a rich cache of fossils in the early 1950s, including articulated specimens of new species (the small sauropodomorph dinosaur Pantydraco caducus and the crocodylomorph Terrestrisuchus gracilis), but no substantial study of the wider fauna of the Pant-y-ffynnon fissure systems has been published. Here, our overview of existing specimens, a few described but mostly undescribed, as well as freshly processed material, provides a comprehensive picture of the Pant-y-ffynnon palaeo-island of the Late Triassic. This was an island with a relatively impoverished fauna dominated by small clevosaurs (rhynchocephalians), including a new species, Clevosaurus cambrica, described here from a partially articulated specimen and isolated bones. The new species has a dental morphology that is intermediate between the Late Triassic Clevosaurus hudsoni, from Cromhall Quarry to the east, and the younger C. convallis from Pant Quarry to the west, suggesting adaptive radiation of clevosaurs in the palaeo-archipelago. The larger reptiles on the palaeo-island do not exceed 1.5?m in length, including a small carnivorous crocodylomorph, Terrestrisuchus, and a possible example of insular dwarfism in the basal dinosaur Pantydraco. 相似文献

The effect of water on accessory phase solubility in subaluminous and peralkaline granitic melts 总被引:4,自引:0,他引:4
The solubilities of columbite, tantalite, wolframite, rutile, zircon and hafnon were determined as a function of the water contents in peralkaline and subaluminous granite melts. All experiments were conducted at 1035 °C and 2 kbar and the water contents of the melts ranged from nominally dry to approximately 6 wt.% H2O. Accessory phase solubilities are not affected by the water content of the peralkaline melt. By contrast, solubilities are affected by the water content of the subaluminous melt, where the solubilities of all the accessory phases examined increase with the water content of the melt, up to 2 wt.% H2O. At higher water contents, solubilities are nearly constant. It can be concluded that water is not an important control of accessory phase solubility, although the water content will affect diffusivities of components in the melt, thus whether or not accessory phases will be present as restite material. The solubility behaviour in the subaluminous and peralkaline melts supports previous spectroscopic studies, which have observed differences in the coordination of high field strength elements in dry vs. wet subaluminous granitic glasses, but not for peralkaline granitic glasses. Lastly, the fact that wolframite solubility increases with increasing water content in the subaluminous melt suggests that tungsten dissolved as a hexavalent species. 相似文献

Calcite samples were extracted both from the rock matrix and the superficial coating of a karstified fault plane of an underground quarry, located in the eastern border of the Paris basin. The karstification is dated as Quaternary. Analysis of mechanical calcite twinning reveals that only the calcite matrix has also undergone a compression trending WNW that can be attributed to the Mio-Pliocene alpine collision. Both coating and matrix have undergone a strike-slip regime with σ1 roughly trending north–south, that could correspond to the regional present-day state of stress, a strike-slip compression rather trending NNW, modified by local phenomena.
