Deep time is, to me, one of the most awe-inspiring concepts to come out of the earth sciences. Getting to grips with the incomprehensibly vast stretches of time over which geological processes play out is not easy. We are, in the words of geologist Marcia Bjornerud, naturally chronophobic. In Notes from Deep Time, author Helen Gordon presents a diverse and fascinating collection of essay-length chapters that give 16 different answers to the question: “What do we talk about when we talk about deep time?” This is one of those books whose title is very appropriate.
Volcanoes are some of the most awe-inspiring natural spectacles on our planet. There is much more to them, though, than the stereotypical image of a conical fire-spitting mountain, and I have been keen to learn more. As I searched for serious introductory books on volcanology, this was one title that kept coming up. But wait, why is a biologist reviewing geology textbooks?
Judging by the title of this book, you might expect it to talk of 25 remarkable kinds of rocks and minerals. But in the preface, geologist and palaeontologist Donald R. Prothero makes clear that his book looks as much at famous outcrops and geological phenomena. Bringing together 25 readable and short chapters, he gives a wide-ranging tour through the history of geology, celebrating the many researchers who contributed to this discipline.
When it comes to big volcanic eruptions, names such as Vesuvius, Mount Saint Helens, and Krakatau will ring a bell. But all of these are dwarfed by a far larger eruption that few outside of the science community will have heard of. Noted geologist, palaeontologist and author Donald R. Prothero here tells the story of the eruption of Mount Toba in what is nowadays Sumatra, Indonesia, some 74,000 years ago. An eruption so gargantuan that it almost wiped out the human race.
I will immediately admit that I have retained a boyish fascination with volcanoes. And, as Volcanoes: Encounters Through the Ages shows, I am not alone. Written by volcanologist David M. Pyle to accompany a 2017 spring exhibition at the Bodleian Library in Oxford, this book brings together many historical illustrations from their collections to show how volcanoes have been represented and described over time, and how this has shaped our present understanding. I have not visited the Bodleian Library before, but this book makes me wish I had.
