Geology of the Country Around Pwllheli


Book Description

The district described in this memoir (1:50 000 geological sheet 134) covers the central area of the Llyn Peninsula in north-west Wales. The solid rock types vary from deformed m'lange and Precambrian granites, through an array of Cambrian and Ordovician clastic sedimentary rocks, to a wide range of tholeitic to alkaline and ultrabasic to acid igneous rocks.

A Revised Correlation of Ordovician Rocks in the British Isles


Book Description

&Quot;This Report is revised and expanded from the 1972 publication, providing an up-to-the-minute account of the British Ordovician formations and their correlation nationally and internationally. It also includes the most comprehensive treatment of Ireland ever attempted. The reference list is a comprehensive bibliography of papers on the subject published since 1970.". "This Special Report will be a valuable reference for research and applied geoscientists working with rocks of Ordovician age. It will be of particular interest to those working in, or visiting, the Welsh mountains and the English Lake District."--BOOK JACKET.




Geology of the Country Around Cadair Idris


Book Description

The Cadair Idris district lies at the southern edge of the Snowdonia National Park and, from the high ridges of the Cadair Idris massif to the tidal reaches of the Mawddach and Dyfi estuaries, it is an area of spectacular beauty. For many geologists it is a special place as it lies close to the heart of Sedgwick's Cambrian System. The survey of the Cadair Idris district has followed those of the Harlech, Snowdon and Bangor districts to the north and has broadened the correlation of the Cambrian and Ordovician sequences in north-west Wales.




Natural Stone and World Heritage


Book Description

This book is about the stone used to build the castles of Edward I in North West Wales. It provides a description of the available geological resources and the building materials used in the construction of Caernarfon, Conwy, Harlech and Beaumaris Castles. It takes a broad view of this subject, placing the stone used in the castles in the context of both earlier and later buildings across the region of study, from the Neolithic up until the present day. The book will serve as a useful source book for geologists, archaeologists, architects, representatives of the natural stone industry, historians and cultural heritage management professionals specifically and for academic and non-academic communities, travellers and tourism industry operators in general.
