摘要

在东法夫克雷尔附近的因弗克莱德群Balcomie地层中发现了一个火山成因粘土层（tonstein）。它的化学成分表明它是一个不饱和的碱性岩浆源。该层位可能与东洛锡安石炭纪早期Garleton Hills管溶熔岩同期（346 马）。这将使其成为法夫保存的石炭纪火山活动的最早表现，也是法夫最早出现的tonstein。

Volcaniclastic deposit (tonstein) in the Balcomie Beds, Lower Carboniferous, East Fife

A volcanogenic clay bed (tonstein) has been identified in the Balcomie Beds of the Inverclyde Group near Crail, East Fife. Its chemical composition suggests an undersaturated alkaline magma source. This horizon may be contemporaneous with the early Carboniferous Garleton Hills trachytic lavas of East Lothian (346 Ma). This would make it the earliest expression of Carboniferous volcanism preserved in Fife, and also the earliest occurrence of a tonstein in Fife.

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.
