Abstract

The lithological succession of the Bouldnor Formation of the Isle of Wight is described in detail for the first time, and correlations are made between successions on the northwest of the island (Bouldnor, Thorness, Gurnard) that in the southeast (Whitecliff–Howgate). The succession comprises rhythmically bedded clays and silts, containing numerous palaeosols and detailed correlation is enabled by a series of lithological and faunal marker beds. Many of these represent brief, but very widespread, brackish transgressions on a muddy coastal plain. The succession in the south-east of the island is markedly coarser, containing numerous silt beds. There is evidence of structural control by contemporaneous movements on the Bouldnor Syncline and Porchfield Anticline.

英国怀特岛博尔德诺组（索伦特群，始新世-渐新世）地层

首次详细描述了怀特岛Bouldnor组的岩性序列，并对该岛西北部（Bouldnor、Thorness、Gurnard）与东南部（whiteccliff - howgate）的岩性序列进行了对比。该序列包括有节奏的层状粘土和粉砂，包含大量的古土壤，并通过一系列岩性和动物标志层进行详细的对比。其中许多是在泥泞的沿海平原上短暂但广泛的微咸海侵。岛屿东南部的地层明显较为粗糙，含有大量的淤泥层。博尔德诺向斜和波尔奇菲尔德背斜的构造受同时期运动的控制。

期刊介绍： The Proceedings of the Geologists'' Association is an international geoscience journal that was founded in 1859 and publishes research and review papers on all aspects of Earth Science. In particular, papers will focus on the geology of northwestern Europe and the Mediterranean, including both the onshore and offshore record. Following a long tradition, the PGA will focus on: i) a range of article types (see below) on topics of wide relevance to Earth Sciences ii) papers on aspects of Earth Science that have societal relevance including geoconservation and Earth management, iii) papers on palaeoenvironments and palaeontology of the Mesozoic and Cenozoic, iv) papers on aspects of Quaternary geology and climate change, and v) papers on the history of geology with particular reference to individuals that have shaped the subject. These topics will also steer the content of the themes of the Special Issues that are published in the PGA.
