Abstract

An early stage in formation of a composite debris cone in the glacial trough of the Lochan na Lairige, on Ben Lawers, is 14C dated to 6398–6225 cal years BP. A large proportion of the debris cone comprises a structureless gravel with boulders, possibly deposited in a single event. Blanket peat formed on the debris cone surface at 3820–3496 cal years BP. Sediment slurries are recorded across the peat after this time, at c. 3950–c. 3100, c. 2000 and c. 1400 cal years BP, and at c. 1200–c. 1100 cal years BP. They were much less significant events. They can be related to periods of higher effective precipitation in the region.

Ben Lawers Lochan na Lairige多期复合碎屑锥地层学的放射性碳年代测定

Ben Lawers上Lochan na Lairige冰川槽中复合碎屑锥形成的早期阶段为14C，日期为6398–6225 cal年BP。大部分碎屑锥由无结构砾石和巨石组成，可能在一次事件中沉积。3820–3496年碎屑锥表面形成的覆盖泥炭 cal年BP。在这段时间之后，在约3950–c。3100年，约2000年和约1400年 cal years BP，约1200–c。1100 cal年BP。它们的重要性要小得多。它们可能与该地区有效降水量较高的时期有关。

期刊介绍： Although published only since 1965, the Scottish Journal of Geology has a long pedigree. It is the joint publication of the Geological Society of Glasgow and the Edinburgh Geological Society, which prior to 1965 published separate Transactions: from 1860 in the case of Glasgow and 1863 for Edinburgh. Traditionally, the Journal has acted as the focus for papers on all aspects of Scottish geology and its contiguous areas, including the surrounding seas. The publication policy has always been outward looking, with the Editors encouraging review papers and papers on broader aspects of the Earth sciences that cannot be discussed solely in terms of Scottish geology. The diverse geology of Scotland continues to provide an important natural laboratory for the study of earth sciences; many seminal studies in geology have been carried out on Scottish rocks, and over the years the results of much of this work had been published in the Journal and its predecessors. The Journal fully deserves its high reputation worldwide and intends to maintain its status in the front rank of publications in the Earth sciences.
