Tourmalinization in the Dartmoor Granite
Rock-Forming Minerals
Author: William Alexander Deer
Publisher: Geological Society of London
ISBN: 9781897799895
Category : Science
Languages : en
Pages : 646
Book Description
This part deals mainly with the disilicates and ring silicates including the epidote, melilite, cordierite and tourmaline groups. In addition to the minerals dealt with in the first edition, some of the rarer but typical minerals in the calc-silicate rocks and the accessory minerals of nepheline-syenites and related rocks have been included. The orthosilicates, in particular the olivine, garnet and humite groups are covered in Volume 1A.

Igneous Rocks of South-West England
Author: P.A. Floyd
Publisher: Springer Science & Business Media
ISBN: 9401115028
Category : Science
Languages : en
Pages : 257
Book Description
This volume illustrates some of the significant aspects of magmatic activity from Devonian (408 million years ago) to early Permian (270 million years ago) times in SW England. This period covers the progressive development of the Variscan mountain-building episode, from initial basin formation to final deformation and the subsequent development of a fold mountain belt - the Variscan Orogen. Both extrusive (volcanic) and intrusive (plutonic) rocks are found in the orogen, and chart the various stages of its magmatic development. The sites described in this volume are key localities selected for conservation because they are representative of the magmatic history of the orogen from initiation to stabilization. Some of the earliest volcanic activity in the Devonian is represented by submarine basaltic and rhyolitic lavas developed in subsiding basins, caused by the attenuation of the existing continental crust. In some cases, extensive rifting and attendant magmatism produced narrow zones of true oceanic crust, whereas elsewhere basaltic volcanism is related to fractures in the continental crust at the margins of the basins. After the filling of the sedimentary basins, and their deformation caused by crustal shortening (late Carboniferous Period), further activity is manifested by the emplacement of the Cornubian granites and later minor basaltic volcanism in the early Permian. Accounts of the constituent parts of this history have enriched geological literature from the nineteenth century onwards, and have contributed to the advancement and understanding of magmatic and tectonic processes.

The Geology of England and Wales
Author: P. J. Brenchley
Publisher: Geological Society of London
ISBN: 9781862392007
Category : Science
Languages : en
Pages : 588
Book Description
This second edition of 'The Geology of England and Wales' is considerably expanded from its predecessor, reflecting the increase in our knowledge of the region, and particularly of the offshore areas. Forty specialists have contributed to 18 chapters, which cover a time range from 700 million years ago to 200 million years into the future. A new format places all the chapters in approximately temporal order. Both offshore and economic geology now form an integral part of appropriate chapters.
