Among the topics covered by the 12th plenary meeting of the Commission of Geomorphology were 1) status of geomorphological research and mapping in the U.S.S.R., 2) application of geomorphology in construction and mineral prospecting, 3) geomorphological training, and 4) standardization of mapping procedures and symbolism. The plenum went on record as favoring maps based primarily on genetic classification of features.—M. Russell. 相似文献

The occurrence of the rare phenomena of a booming sand is recorded and an account given of its behaviour in the field. Its sedimentological properties are compared with those of a squeaking sand from the seashore. Both sands are moderately to wellsorted, and show similar roundness and sphericity. The desert sand is silent, whereas the seashore sand can be made to emit a noise in the laboratory. The marked distinction between the sands lies in the mechanical analyses based on the number frequency of grains, rather than on the weight frequency. A “body-centred cubic” packing has been proposed for the desert sand and a “rhombic” packing for the seashore. Shear-box tests on the disturbed sands appear to support the hypothesis of two different modes of packing. The source of the characteristic booming sound is discussed, but it is suggested that an explanation is more likely to be forthcoming from field investigation than from small-scale laboratory studies. 相似文献

Hest bien clair que toute reponse a cette question, sera du plus haut interet pour les geologues de la Chine, vu que les resultats de la geodesie semblent bien indiquer que la croute terrestre est divisee en plusieurs blocs independants, juxtaposes et equilibres isostatiquement. 相似文献

志留系在博罗科努山地区分布比较广泛,且厚度巨大,岩性、岩相稳定。但对其内部划分,尤其是中、上部,缺乏标准化石作为依据。1988年笔者在原划归上统的库茹尔组中,首次采到角石Sichuanoceras sp., Parahelenites cf. rarus和三叶虫Encrinurus sp.等化石。因而库茹尔组很可能属志留系中统,而非上统。 相似文献
