Postage stamps are useful in promoting geological heritage. This concept is explored through an analysis of British and New Zealand stamps, which portray a variety of different types of geological heritage. Coastal, glacial, fluvial and limestone scenery all feature, together with volcanic landforms such as the Giant's Causeway. Other stamps celebrate the work of historically significant figures who have contributed to geology, such as Charles Darwin. The field of palaeontology is represented in stamps, for example, featuring dinosaurs. Others portray economic activities and engineering achievements associated with geology such as oil and gas exploration. Industrial heritage is depicted by stamps featuring, for example, abandoned tin mines, while building stones are represented in stamps of ancient monuments, bridges, cathedrals and domestic architecture. Perhaps subjects for future stamp issues in the UK might draw upon the recently published 100 top geosites list. 相似文献

Stamps convey important visible messages about a state’s heritage and worldview. They are images or official visible products seen by those living within the state’s borders and those beyond. They also can be considered as “imagined communities,” as like festivals, holidays, or WWW pages, they represent attachments to and images of place. We investigate stamps as elements of visual culture by examining salient music themes and topics from several countries and then focus on the music stamps of Brazil, Hungary, and Senegal. In each case, we examine the number and variety of issues, the importance they place on musical instruments, composers and performers, and musical events. 相似文献

Over a continental area, the sediments are mostly found, either asoriginally spread by water along the slopes (gravels or loams: fan-deposits), or as accumulated by streams in the bottom of the basins(lake-deposits, or fluvial plains), either as disseminated by wind (sand-dunes and loess deposits). 相似文献

金顶铅锌矿床地质-地球化学 总被引:49,自引:2,他引:49
金顶铅锌矿床的成矿作用发生在中-新生代沉积地层当中,且矿区内没有明显出露岩浆岩,矿体为板状,产在古新统统云龙组和下白垩统景星组的陆相碎屑岩中,但成矿并不受岩相地层控制,而受断裂和穹隆构造控制。铅同位素数据指示成矿金属主要为自地幔。硫同位素具有δ^34S黄铁矿>δ^34S闪锌矿>δ^34S方铅矿的趋势,硫主要来自地壳,闪锌矿及有关脉石矿物(石英,天青石,方解石和硬石膏)的流体包裹体研究表明,均一温度主要在110-150℃,盐度ω(NaCleq)5.09%-19.63%,成矿压力32.5-22.6MPa,所对应的成矿深度0.9-1.5km。 相似文献

The mining environment, medical geology and urban geochemistry form a group of related scientific disciplines that have developed strongly during recent years in the Nordic countries. Modern legislation controls the environmental issues. Close co-operation of researchers and legislators has improved the quality and safety of life in the societies of the Nordic countries. In mining environmental studies, methods that are suitable in Arctic conditions have been developed; in medical geology, the input from the Nordic countries has made it an appreciated scientific discipline throughout the world, and in the case of the urban environment, methods developed by our geochemists have especially improved the health conditions, particularly of children. 相似文献
