Moraine ridges have been morphologically and seismically identified in the south-western Barents Sea. Some of these ridges were deposited in front of ice lobes from the northern part of the Fennoscandian Ice Sheet, others in front of glaciers located on the southern Barents Sea shelf. The moraine ridges were probably deposited during the Weichselian, possibly the Late Weichselian.  相似文献   

Chitinozoan biostratigraphy of the early Caradocian Lockne impact structure,Jämtland,Sweden     

YNGVE GRAHN 《Meteoritics & planetary science》1997,32(6):745-751

Abstract— The chitinozoan biostratigraphy in seven outcrops and four drilling cores in connection with the Lockne impact structure has been investigated. The impact event took place in early Caradoc (i.e., ～460.4 Ma ago) and in beds corresponding to the lower part of the Lagenochitina dalbyensis Zone (upper Dalby Limestone). The contact between the impact-related rocks and the secular postimpact sediments can be traced all over the impact structure, and up to a distance of 50 km away from the presumed crater center. The youngest postimpact sediments in the Lockne impact structure correspond to the lower Örå Shale (Belonechitina hirsuta Zone).  相似文献
