P W Forster (UK) I have many years of experience collecting and cutting agates. It was my wife who originally had an enthusiasm for these beautiful semi-precious stones and it was because of her enthusiasm that I developed an interest that has now become an obsessive hobby for the both… … Read More
Stephen K Donovan (The Netherlands) This is the first of six articles that will introduce the geology of the Antillean island of Barbados. It is an expanded and more detailed guide derived from two earlier publications (Donovan & Harper, 2005, 2009). The structure of the guide will include a summary… … Read More
Mugdha Chimote (India) The term ‘Quaternary’ is derived from the Latin word “Quaternarius” (meaning “four”, such that the Quaternary is “the fourth great epoch of geological time” in the now-abandoned system of dividing geological time). It refers to the most recent period of the Earth’s history, covering a span of… … Read More
Mugdha Chimote (India) The Deccan Traps occupy approximately 25% of the total of peninsular India, that is, the triangular shaped landscape of southern India. They traverse the states of Maharashtra, Karnataka, Madhya Pradesh, and Gujarat. The Deccan Traps are currently believed to occupy about 500,000km2 of northwest peninsular India. It… … Read More
Mugdha Chimote (India) Introduction Sandwiched between the Arabian Sea to the west and the vast Indian subcontinent to the east, the Western Ghats, a haven for trekkers and travellers, are a 1,600km long range of mountains along western edge of Deccan Plateau. Also known as “Great Escarpments of India”, the… … Read More
Deborah Painter (USA) “Look over there!” I exclaimed as I stood on the grounds of a manufacturing plant and stared across the tracks of the Atchison, Topeka and Santa Fe Railroad to the east of the plant. I was pointing at several mountains a few kilometres in the distance. “That… … Read More
Dr Robert Sturm (Austria) The mineral zircon (more correctly, orthosilicate zircon or ZrSiO4) is an important accessory mineral in various rocks of the earth’s crust, but most of all of igneous rocks with the mineral composition of granite. An accessory mineral is a mineral comprising less than about 10% of … Read More
Robert Sturm The Isle of Skye is a part of the Inner Hebrides in the north-west of Scotland. It has a total area of 174,000 hectares and has an irregularly shaped coastline that is typical of the British Isles. Since the early nineteenth century, the island has become a centre… … Read More
This is a lovely book – a glorious mixture of a beautiful coffee-table book and an academic treatise of the highest quality. But why microfossils? What is it about them that can create such strong feelings?
Robert Sturm (Austria) During the last few decades, the interest of diverse geosciences has increasingly focussed on the examination of so-called ‘shear zones’, because the displacements between two lithological blocks represent natural ‘laboratories’, within which the phenomena of mineral alteration and deformation are clearly shown for the purposes of scientific… … Read More
I don’t normally review BGS memoirs – they are excellent publications, but largely written for the professional or the seriously committed amateur geologist. (I have to admit to owning several, which cover my favourite fossil collecting areas of the UK.) However, this is one ‘Special Memoir’ that I am quite willing to make an exception for.
Dr Robert Sturm (Austria) Exploitation of gold deposits in the Hohe Tauern, in the Central Alps of Austria, has a long history: occurrences of this noble metal were explored for the first time about 2,000 years ago. Since the fourteenth century, the search for gold has been conducted on an… … Read More
Dr Robert Sturm (Austria) When talking about precious or semi-precious gemstones, most people think of the diamonds they cannot afford or rubies, agates and similar well-known minerals. But, only a few people know that gemstones have been subjected to various carving techniques since ancient times, making from them small but… … Read More
The Jurassic Coast Trust is certainly producing some good books these days. I have alraedy reviewed one (The Jurassic Coast: An Aerial Journey through time by Peter Sills) and I think these two might even be better. As is well known, in recognition of its wonderful geology, the coast between Orcombe Rocks in southeast Devon and Old Harry Rocks in south Dorset was granted World Heritage status in December 2001.

Diana Clements (UK) The Geologists’ Association (GA) was formed in 1858 and, from its inception, was an inclusive organisation set up to embrace both professional and amateur geologists, unlike the Geological Society, some 50 years older, which was only intended for professionals. Women were accepted from the beginning – similar… … Read More
In recent years, Graham Park has been prolific in his writing for Dunedin Academic Press. In this new tome, he has produced what I suspect is a really great introduction to a range of key concepts and geological processes for both undergraduates and the interested, moderately well-informed amateur.
If you can see past the somewhat robust title (a reference to James Hutton’s discomfort riding around Scotland on horseback during his geological investigations), this is an interesting read, combining both geological science and humour in just about the right measures.
The Geologists’ Association has produced yet another great guide, this time on the geology of Wales. However, this is a slightly different beast from most of their other publications.
Ken Madrell (UK) Introduction Most visitors to the Cyclades islands will gravitate to the island of Santorini to see its stunning caldera and the magnificent sunsets from the northern town of Oia. The island is part of the Aegean volcanic arc formed by the subduction of the African plate under… … Read More
Jon Trevelyan (UK) This is the much anticipated 4th edition of the GA’s Yorkshire Coast guide and it was well worth the wait.

Benjamin Hayden Elick and Steven Wade Veatch (USA) The Cresson mine (Fig. 1) – situated between Cripple Creek and Victor in Colorado – was established in 1894 (MacKell, 2003). No one is certain who started the mine, but records show that two brothers, insurance agents, J R and Eugene Harbeck from… … Read More
Steven Wade Veatch USA) Michigan’s puddingstones are intriguing rocks that look like a glob of pudding stuffed with raisins, nuts and bits of cranberries. These white rocks with small red, brown, purple and black pebbles are not a Michigan product. During the last ice age, they hitched a ride into… … Read More
