Geology news


William sent in a link to ...but see also ... this concerns the conflict of interest between geologists over the K/T event. Was it the asteroid that killed off the dinosaurs or was it volcanism. This new study favours the asteroid.

Zealandia Geophysics

A new interactive map of the lost continent of Zealandia has been produced - see ... the map allows viewers to explore the geoscience data that shows the bathymetry and tectonic origins of the earth's eighth continent. It is a largfe area of submerged continental crust that became submerged around 23 million years ago, it is said.

Insects and Geology

Is this biology or is it geology. Bit of both. At .... the discovery of a tiny insect fossil is said to uncover a history of global movements of animals and the shifting continents across deep time. The 50 million year old fossil was found near Kamloops in Canada but in the modern world its descendants live in Australia. The problem with the press release here is that 50 million years ago is not  deep time and is post-K/T boundary and therefore post Pangea.

Coal Burning Climate Change

This one was sent in by William but I've found the following three links ... at ... which comes with lots of comments, some of which are useful. The story is about coal contributing to the Permian/Triassic boundary event as a result of persistent volcanism in Siberia (which according to uniformitarian geology continued over many hundreds of thousands of years, even millions of years according to some geologists).

Ocean Crust Waves

Robert also sent in a link to ... the search for the missing plane, Malaysia Airlines Flight 370, which disappeared in the Indian Ocean back in 2014, led to a long and  detailed search of 18,000 square km around the SE Indian Ridge, west of Australia. They didn't find the aeroplane but they did produce a series of sea floor maps that found a geological puzzle previously unknown.

Sand over the Ocean

Robert sent in the link ... giant sand cloud from the Sahara is blowing across the Atlantic. It may reach as far as Louisiana and Texas. Robert comments - stratospheric winds blow east to west at this time of the year. Do they have something to do with the phenomena? See for example stratospheric winds in real time at ....


A behemoth ammonite - not the fabled Jewish or Canaanite monster. At ... as sent in by Robert. An enormous fossil ammonite weighing over 200 pounds and 2 feet in diameter has been found by fossil hunting students on the Isle of Wight. No doubt they have been using lockdown to good use. It took them ten hours to extract it from the rock face. They say it goes back to the Cretaceous period - although ammonites are found in earlier strata. The Isle of Wight is chalk country - hence its name ....

The Planet's Core

At ... scientists detect unusually hot and dense structure near the planet's core - via seismic echoing ...

 .... they are referring to the boundary between the molten core and the Mantle layer above it. Areas of unusually dense rock have been found .....

Mammal Evolution

At .... a fossil discovery reveals the earliest relative of modern mammals - going back 300 million years ago. That is a very long time ago and you will not be surprised to learn that it is a mammal like reptile, a synoside. The fossil came from Nova Scotia - from the remains of a vast fossil forest. At the time Nova Scotia was located near the equator, it is thought.
