2009 recipient of the Geological Association of Canada Neale Medal Have you ever been walking at the beach and wondered what that pebble or rock is, or do you ever wonder what stories rocks tell? If so, then this is the guide for you. The Field Guide to the Identification of Pebbles , a full colour, laminated, accordion folded, easy to use guide with over 80 beautiful photographs of pebbles from beaches and rivers. Use the photos to identify over 28 different types of rocks and minerals. A great resource for Earth Science curriculum units in schools, the short text deals with how rocks form and how to tell if a rock is igneous, sedimentary or metamorphic. It also provides some fun facts about minerals in our daily lives.
This fourth edition builds on the success of previous editions and for the first time is produced in full colour throughout with improved photos and diagrams. It retains its popular pocket size and is an essential buy for all students working in the field. The text shows how sedimentary rocks are tackled in the field and has been written for all those with a geological background. It describes how the features of sedimentary rocks can be recorded in the field particularly through the construction of graphic logs. In succeeding chapters the various sedimentary rock types, textures and structures are discussed and shown how they can be described and measured in the field. There are expanded sections on trace fossils and volcaniclastics along with updated reference list. Finally a concluding section deals briefly with facies identification and points the ways towards facies interpretations, and the identification of sequences and cycles. Key Features: Full colour throughout with improved photos, figures and diagrams in a modern layout. Complete revision and update of best selling textbook which is part of the highly successful Field Guide series. Expanded sections on trace fossils and volcaniclastics along with updated reference list. Handy pocket size with laminated cover. Includes supplementary website with downloadable logging sheets for fieldwork activities.

Sediments are the most valuable form of physical evidence for past Earth surface processes. They have the potential to build up an archive of events and provide a window into the past. Through careful examination of sediments the shifting patterns of surface processes across space and time are revealed, allowing us to reconstruct past environments and environmental change. A Practical Guide to the Study of Glacial Sediments is a guide to the standard techniques employed to read the sedimentary record of former glaciers and ice sheets. It demonstrates that the often complex and fragmentary glacial sedimentary record can, when examined systematically and rationally, provide detailed insights into former environments and climates in places where no other evidence is available. The complementary techniques covered in this book include: facies description, grain size analysis, clast form assessment, clast macrofabric analysis, micromorphology, particle lithology and assessment of engineering properties. They yield consistent and meaningful results in a range of glacial depositional environments throughout the world, from the high Arctic to the Himalayas. A Practical Guide to the Study of Glacial Sediments provides students and researchers with a clear and accessible guide to recording and interpreting glacial successions wherever the location.
Next to collecting colourful pebbles, there are few more enjoyable ways to spend a relaxing afternoon than at the seashore collecting ornate seashells. But there is no need to fly away to some exotic tropical locale to begin the fun. If you are in the Pacific Northwest, you will find local beaches as rich in fascinating treasures as any place on earth--or at least you will once you have this handy eight-fold guide to show you where to look and how to identify what you find. Those whose interest in shellfish is mainly gastronomic will also find this waterproof guide an essential tool. The most common clams, oysters and mussels are well-known, but which are safe to eat? Is there any truth in the old saying about months with the letter "R" in them? How long should a harvester wait after a bout of red tide? How do you tell a Manila clam from a butter clam? Where does the fabled geoduck lurk? Is there any foolproof method for catching the elusive razor clam? And what about the multitude of other shell-dwellers that populate our beaches--do they all have names? "A Field Guide to Seashells and Shellfish of the Pacific Northwest" answers all these questions and more. Here for the first time is a pocket-sized, user-friendly guide to the most popular of all beach creatures, written and photographed by one of the region's most outstanding marine life experts.
