Abstract

ABSTRACT The Faroe Islands are characterized by high rates of Holocene geomorphological activity and demonstrable vegetation change, including substantial peat formation. Pedogenesis, especially in the late Holocene, is less well known. Numerous ferruginous rhizoconcretions consisting predominantly of Fe-oxyhydroxides were identified in loam and silty sands in Søltuvík on the island of Sandoy, dated prior to AD 1000. Their formation is related to intensive podzolization and they take the form of the source woody vegetation. The sub-fossil material represents the first evidence for ferruginous rhizoconcretions in the Faroese archipelago.

晚全新世土壤过程和法罗群岛凉爽亚极地环境中含铁根结的第一个证据

法罗群岛的特点是全新世地貌活动率高，植被变化明显，包括大量泥炭的形成。成土作用，特别是在全新世晚期，鲜为人知。在桑多伊岛Søltuvík的壤土和粉砂中发现了大量主要由铁氧氢氧化物组成的含铁根结菌，其年代早于公元1000年。它们的形成与强烈的灰化化有关，并以木本植被的形式存在。亚化石材料代表了法罗群岛中含铁根结的第一个证据。

期刊介绍： Geografiska Annaler: Series A, Physical Geography publishes original research in the field of Physical Geography with special emphasis on cold regions/high latitude, high altitude processes, landforms and environmental change, past, present and future. The journal primarily promotes dissemination of regular research by publishing research-based articles. The journal also publishes thematic issues where collections of articles around a specific themes are gathered. Such themes are determined by the Editors upon request. Finally the journal wishes to promote knowledge and understanding of topics in Physical Geography, their origin, development and current standing through invited review articles.
