Geology of the Dolomites

The Dolomites region is a spectacularly exposed portion of the Southern Alps, a northern Italian chain derived from the comparatively gentle deformation of the Tethyan passive continental margin of Adria. The regionhad an active Permo-Jurassic tectono-magmatic evolu-tion, leading from Permian magmatism, through a Mid-die Triassic episode offast subsidence and volcanism, to the Jurassic oceanic break-up. Although the sedimentary succession ranges in age from Middle Permian to Creta-ceous, the geological landscape is largely dominated by the majestic Triassic carbonates, making the area a clas-sical one for the early Mesozoic stratigraphy. Particu-larly noteworthy are the Anisian to Carnian carbonate platforms, recording an evolution from regional muddy banks to isolated high-relief builduos. The hlline of the various basins and the development of a last generation of regional peritidal platform followed. The carbonate platforms of the Dolomites bear witness to a remarkable set of changes in the carbonate production and to signif-icant palaeoclimatic fluctuations,from arid to moist con-difions and vice versa; a great range of margin and slope depositional styles is therefore recorded. Alpine tectonic shortening strongly affected the area, with a first Eocenede formation, followed by later Neogene overthrusting and strike-slip movements.

定位服务忙天涯若比邻

据说人类80%的活动都与地理位置相关,由此而产生了许许多多的与“位置”相关的技术与服务,从远古的路标、地图、……,到当今时髦的GIS、导航系统、……,都是每个人日常生活与工作中不可缺少的一部分。与此同时,人类的通讯手段也在不断发展,无线通讯已将“天涯咫尺”变为现实,以至于见到某个人对着电话说“您现在在哪儿,在国内吗?”时,已不会有人觉得奇怪了。得益于人类80%活动的需求和现代通讯技术的发展,定位服务(LocationBasedService,LBS)得以产生并飞速发展。LBS是多学科交叉融合的产物,它将无线通讯技术、互联网技术、空间数据库…     

Medical geology：new relevance in the earth sciences

The interdisciplinary fieldresponds to the need to betterof “Medical Geology“ understand the relationships between human health and our surrounding environment. The influence of earth resources, natural environmental factors and land-use on human health has long been recognized, dating back to ancient Rome and Peru‘s Inca civilization. Today links between the natural environment and health can be found throughout the world. This review introduces the historical context of this particular type of research, contrasts the direct geological and indirect natural hazard influences on healthas a framework of study, elaborates on pathways of elemental accumulation in the body and provides examples of specific geochemical behaviours and diseases that are often associated with either too much or not enough of certain elements which comprise the Earth.
