Book review: Iceland: Classic Geology in Europe (3rd edition), by Thor Thordarson and Ármann Höskuldsson

21/02/2022

reviewed the 2nd edition of this guide a while ago and, as I said then, Iceland seems to set the hearts of certain geologists racing and, reading this field guide and that previous incarnation, it is abundantly clear why. Iceland’s fascinating geology is clearly set out in this concise and authoritative book. The island, astride the Mid-Atlantic Ridge, is a ‘natural laboratory’ where the earth sciences can be watched in real-time. Rifting of the crust, volcanic eruptions and glacial activity are among a host of processes and features that can be observed in this fascinating land.

Book review: Introducing Geophysics, by Peter Styles

31/01/2022

Notwithstanding the somewhat daunting use of the word “geophysics” in the title, this is another great book in Dunedin’s Introducing Earth and Environmental Sciences series of guides. In fact, In fact, the only real way to understand the Earth, in all its large and slow-moving immensity, is to study its physics and that means using the classical disciplines of heat, gravity, magnetism, electricity, vibrations and waves. That is, everything we know about the deep Earth has been learnt from geophysics.

Book review: Introducing Tectonics, Rock Structures and Mountain Belts (2nd edition), by Graham Park

30/07/2021

The second edition of this guide is written to explain the key concepts of tectonics and rock structures to students and to interested amateurs. I have reviewed a number of Graham Park’s books in recently years (see below) and he is clearly a prolific and excellent writer of books about the earth sciences.

Plate tectonics (Part 4): More on the rock cycle

26/05/2021

Helen Gould (UK) In Plate tectonics (Part 3): The rock cycle, I presented an overview of the relationship between the rock cycle and plate tectonics, and then went on to look more closely at igneous rocks. This time, I want to discuss sedimentary and metamorphic rocks, and review the occurrence … Read More

Plate tectonics (Part 3): The rock cycle

19/05/2021

Helen Gould (UK) What is the rock cycle? Usually, the first thing that budding geologists learn about rocks is that there are three kinds: igneous, sedimentary and metamorphic. These three major kinds are divided up into many different types of rock. For example, marble, slate and metaquartzite are all metamorphic … Read More

Plate tectonics (Part 2): A closer look

12/05/2021

Helen Gould (UK) As we saw last time (Plate tectonics (Part 1): What are they?), the Earth is a pretty dynamic place, with tectonic plates moving about on the surface, driven by convection cells in the upper mantle. But producing a workable theory, which combined most of the observations of … Read More

Plate tectonics (Part 1): What are they?

05/05/2021

Helen Gould (UK) What does “plate tectonics” really mean? The Earth’s surface bears about 20 plates, which are able, over millions of years, to move about on layers beneath the crust. Some of the surfaces of these plates consist of continental crust, some of oceanic crust, some both (Fig. 1). … Read More

Mugdha Chimote (India) The discovery of Quaternary sediments around Godavari River in Maharashtra (Fig. 1) was something of an accident. Sankalia (1952) first encountered these sediments while excavating the Lower Palaeolithic Industry in the region. Upon discovery, Sankalia brought onboard many geologists, such as Prof S N Rajaguru, Shanti Pappu, … Read More
