人类活动是加剧矿山地质环境演化的“催化剂”。矿产资源开采对环境的破坏具有必然性、综合性,对环境的影响有链式放大效应和滞后效应。从项目需求出发,利用遥感技术对湖北省东部矿山开发占地、矿山地质灾害和矿山地质环境恢复治理进行了遥感调查,查明了2013年湖北省东部矿山开发总占地面积为7339.29hm2,2014年较2013年总占地面积增加了1065.44hm2。矿山地质灾害61处,矿山塌陷地质灾害分布具有地理空间差异性,主要分布在鄂城、铁山、金山店、灵乡、殷祖和阳新６大岩体边缘地带。从生态文明建设的角度看,迫切要求人们树立“绿水青山也是金山银山”的理念,转变发展思路,保护好矿山地质环境。遥感调查结果表明：矿山地质环境治理及矿山复绿工程执行时存在区域不平衡性;武汉市、黄石市矿山地质环境的恢复治理与矿山复绿的强度、速度明显高于其他地区,且其近城区的矿区治理力度大、复绿效果好。 相似文献

使用多期、多源遥感影像数据,选择青海省木里煤矿区开展了荒漠化遥感监测及变化趋势与采矿相关性分析研究。根据多期高分辨率遥感影像提取了矿业活动区信息。采用多期TM遥感影像,分别利用光谱混合像元分解和生物量遥感估算模型方法,提取了多期土地荒漠化信息。对采矿扰动下荒漠化驱动因素分析结果表明:矿业活动区内开采面、矿山占地增长驱动了荒漠化,矿山关停、复绿治理则扼制并减轻了荒漠化;矿业活动区外荒漠化主要受人类活动、道路修建、保护治理政策等因素影响。根据研究结果,提出了矿区荒漠化防治对策。 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

Lithostratigraphy, physicochemical stratigraphy, biostratigraphy, and geochronology of the 77–70 Ma old series bracketing the Campanian–Maastrichtian boundary have been investigated by 70 experts. For the first time, direct relationships between macro- and microfossils have been established, as well as direct and indirect relationships between chemo-physical and biostratigraphical tools. A combination of criteria for selecting the boundary level, duration estimates, uncertainties on durations and on the location of biohorizons have been considered; new chronostratigraphic units are proposed. The geological site at Tercis is accepted by the Commission on Stratigraphy as the international reference for the stratigraphy of the studied interval. To cite this article: G.S. Odin, C. R.

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

Some olistolites reworked in a Tertiary flysch of Mount Parnon (Peloponnesus, Greece) exhibit a Late Permian assemblage, dominated by Paradunbarula (Shindella) shindensis, Hemigordiopsis cf. luquensis and Colaniella aff. minima. This association corresponds to the Late Wuchiapingian (=Late Dzhulfian), a substage whose algae and foraminifera are generally little known. Contemporaneous limestones crop out in the middle part of the Episkopi Formation in Hydra, but they are rather commonly reworked in Mesozoic and Cainozoic sequences. The palaeobiogeographical affinities shared by the foraminiferal markers of Greece, southeastern Pamir, and southern China, are very strong (up to the specific level), and are congruent with the Pangea B reconstructions.
