Photo library, explanations and examples of geological phenomena, links to publications.
Although the Geological Society serves the professional geological community, this section of their website is designed for “keystage 2/3 students [and] their teachers, but also contains material that undergraduates will find helpful”.
“The Geological Society of London has a liberal view on the re-use of its published content for legitimate research, study, teaching and communication, provided its legitimate interests are not damaged in so doing. It is essential, however, that any party seeking permission to re-use content from the website makes a formal request to the Geological Society, and that the source of material is fully acknowledged.”
