Abstract

The results of long-term studies of the heavy mineral composition in Neopleistocene basal moraines, carried out according to a unified technique in numerous outcrops in the European Russian Subarctic, are summarized. The heavy fraction of moraines was formed due to the transport of material from three different glacial feeding provinces: distal, transit, and proximal. With the activation of glacier dynamics and increase in the exaration activity of the mainland ice, local features of the underlying rocks had a decisive influence on the moraine composition. Taking into account other lithological data, the established age and spatial tendencies of regular variability in the mineral composition of different-age moraine horizons made it possible to identify reliably their stratigraphic position.

欧洲俄罗斯亚北极新更新世基底冰碛矿物组成的形成

摘要

总结了根据统一技术在欧洲俄罗斯亚北极地区众多露头中进行的新更新世基底冰碛中重矿物组成的长期研究结果。冰碛的大部分是由于来自三个不同的冰川供给省的物质运输而形成的：远端、中转和近端。随着冰川动力学的激活和大陆冰层勘探活动的增加，下伏岩石的局部特征对冰碛的组成具有决定性的影响。考虑到其他岩性数据，不同年龄冰碛层矿物成分规律变化的年龄和空间趋势使得可靠地识别它们的地层位置成为可能。
