地质遗迹分类学及其应用 总被引：23，自引：12，他引：11
地质遗迹是地质作用过程中形成的地质现象, 是最重要、最珍贵的自然遗产。地质遗迹研究是探索地球演化进程和方向的主要内容, 其价值不可限量。在地质公园工作推进过程中, 开展地质遗迹科学意义的评估。对地质遗迹进行科学分类, 是地质公园设计和建设, 科学研究和普及的重要基础。显而易见, 随地质遗迹区域调查和保护规划的广泛开展, 以往地质遗迹分类已难以满足地质公园快速发展的需求, 以系统地球科学为指导的地质学科分类为基础的地质遗迹分类学也就应运而生了。 相似文献

大自然上亿年的沧海桑田留下了数不清的珍贵的地质遗迹,被形象地称为＂人类的记忆＂。地质遗迹是地球演变过程中留下的生物和非生物痕迹,记载着地球沧海桑田的变换。此外,它还是推断与论证地质事件的有力佐证,是寻找与断定矿产资源踪迹的脉搏,是勘验与追寻生命起源的线索,具有极高的科学价值。 相似文献

地质公园及建立地质公园的意义 总被引：1，自引：0，他引：1
地质公园(Geopark)是以具有特殊地质科学意义及较高的美学价值的地质遗迹为主体,并融合其它自然景观与人文景观而构成的一种独特的自然区域。地质遗迹是指地质时期由于内、外动力的地质作用,形成具有典型特征的地质现象或地貌景观,它是不可再生的自然遗产。重要的地质遗迹是宝贵的自然资源,是人类的财富,是自然生态环境的重要组成部分。为了更好的保护地质遗迹、爱护我们的生存的家园———地球,1991年6月13日在法国迪涅召开的“第一届国际地质遗产保护学术会议”上,来自30多个国家的10 0多位代表共同签发了《国际地球记录保护宣言》,该宣… 相似文献

<正>地质遗迹是在地球漫长演化的地质历史时期,由各种内外动力的地质作用形成、发展并保存下来的珍贵的不可再生的地质自然遗产。随着我国地质公园建设的不断深入,对地质遗迹进行科学的评价,成为申报国家或世界地质公园的首要前提,也是地质公园建设中亟需解决的问题。目前,对地质遗迹的评价既包括地质遗迹的资源要素及自身价值,也包括对资源开发的利用条件。而地质遗迹的资源要素及自身价值作为地质公园建设和地质遗迹保护的核心,如何单纯评价地质遗迹的本身价值,需要建立怎样的评价标准, 相似文献

洛川黄土国家地质公园与当地经济互动发展初探 总被引：4，自引：0，他引：4
地质遗迹作为一种具有珍贵地质科学价值和独特造景功能的自然遗产，随着社会经济的发展，其保护与利用之间的矛盾已日益突出。同样，以地质遗迹资源为核心的地质公园也面临着如何协调地质遗迹保护与公园建设之间的矛盾。从以往经验来看，在保护好地质遗迹资源的前提下进行地质公园建设的保护性利用模式是一种有效的解决措施。为此，本文选择黄土国家地质公园作为研究对象，从地质公园建设与当地经济互动发展角度出发，探讨如何进行地质遗迹的保护性利用，从而达到有效保护地质遗迹资源的最终目的。 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.
