Wet Green Sahara

The early to mid Holocene is renowned for the Greening of the Sahara and this implies much higher levels of rainfall than in the modern world - although other causes might be hiding in the closet. The Sahara is a largely stony desert and is dry as a result of little rainfall. Between 11,000 and 5000 years ago it was covered in savannah and pockets of woodland, with lakes and rivers and streams. It was ten times wetter than it is in the modern world. This doesn't tell us a lot as it is bone dry and covered in a system of dry wadis.

Modelling Earth Science

At ... Plate Tectonics models are getting more complicated all the time. Apparently, subduction by itself is not enough to explain how it occurs and internal heat from earth's core is being invoked to provide extra bite to the mainstream mechanism that drives the movement of the plates. There are various mid-ocean ridges identified but in this article in Science Advances (December 2016) we are told the East Pacific Rise is stable - unlike the Mid Atlantic Ridge that may have direct coupling with the deep mantle flow.

Is the black mat in UK

At ... I was looking at the archaeology pages on this web site and flicked on to this page, 'Stratigraphy and Paleoenvironmental Sampling' which is quite revealing as early to mid Holocene is not something you see mentioned much in geology as most of it is absent from most locations. I don't know why they use the American spelling for paleoenvironmental (rather than palaeoenvironmental) or perhaps it's me that is wrong. The findings come from three trenches cut in a river valley in SW Hertfordshire (between Watford and Hemel Hempstead).

India Plate

The second post today is another dust up with consensus science. At ... India, according to Plate Tectonics theory gradually drifted away from Africa and Madagascar towards the NE and eventually collided with southern Asia after millions of years of riding the waves as an isolated island - completely cut off.

Big One

At ... this is the Big One - in more ways than one. It comes just as the Thunderbolts people are telling us craters have origins in electrical phenomena, even the one at Chicxulub that is supposed to have killed off the dinosaurs. A large and mysterious anomaly is hiding beneath the frozen waste of Wilks Land in Antarctica. It is 151 miles across - and has a minimum depth of 2700 feet. Some scientists are thinking in terms of a giant asteroid crater - twice the size of Chicxulub.

bone beds

Bone beds. What are they? It is rare to come across a complete dinosaur skeleton - or even a partial skeleton. These are what scientists like which is why the recent discoveries in China and Argentina have taken such a prominent position in various pieces of research in journals etc. The media of course also like dinosaur skeletons and most of us have been impressed by specimens in natural history museums.


At .... apparently, ocean bottom crust in the modern world is thinner than it was prior to the break up of the supercontinent of Pangea. Plate tectonics has subsequently caused the crust to cool and at the same time thin it. All that heat and plate activity after  170 million years ago is being blamed for a thicker ocean floor crust at that time. The study involves computer modelling.


This is the second time we have had a post on the Atacama desert in Chile. In this post we learn that the desert hosted lakes during the last Ice Age and these may have survived long enough to provide sustenance for humans in their journey from NE Asia to the tip of South America. See
