The North Sea and the Zuidwal volcano

We recently published a post on the Zuidwal volcano, found buried in the Netherlands and becoming a google sensation – google is still working on removing all the made-up images. But in spite of google, there is a real story behind this volcano. It is the story of the North Sea, the sea that could…

The Vredefort impact

The centre of South Africa is an amazing place. The long drive from Cape Town in-land is exciting for the first two hours, while the road climbs up through the mountains, past vineyards and valleys full of fynbos. Once on the high interior plateau of South Africa, the landscape becomes dry and monotonous – and…

Time for komatiite

People mellow with age. (At least, most of us do.) The emotions of youth become less all-important and less demanding of our attention. Young people feel that every perceived slight needs addressing. The heat goes to the head and mistakes are made. Older people consider more before responding. The Earth, too, went through a youthful…

The 1607 Bristol tsunami

Some events can cast long shadows. The UK is still talking about the storm of 1987 (‘the worst night since the Blitz’), the winter of 1963, the storm floods of 1953, the London smog of 1952, the Great Storm of 26 November 1703. Other countries have their own stories. But one event in particular still…

Kerguelen and the demise of Gondwana

Much of our world is in hiding. It lies below the surface of the oceans and is largely invisible to us, a Maria Incognito. It is a hostile world: we are creatures of the solid ground, who long left the seas behind and cannot return. But more of this forbidden world is being uncovered, by…

Saving the Earth with asteroids

A republication of an older post The dinosaurs would disagree. After owning the Earth, they were now in a bit of a bother. A major re-arrangement of the Earth had taken place. Pangea had split; Gondwana was broken up. The Indian ocean had formed but not in a clean way: a number of parallel rifts…

The Dinosaur Egg Hunt of the Deccan traps

Is this the strangest egg in the world? The shell contains no egg white, yoke or embryo, nor even chocolate. No bird will ever hatch from it. Instead it is filled with a stony mineral. Which creature laid it, and what was expected to emerge from it? The only thing that comes to mind is…

Westward drift

Continental drift was dead. The idea had been around for a long time. Just a cursory look at a map shows the similarity between the coast lines on either side of the Atlantic ocean. They fit even more precisely when looking at the continental shelf rather than the actual coast line. Even better, the geology…
