MONDAY 21st

Geostudies - Lecture Series - Ordovician
When
Mon, 21 October, 19:30 – 21:30
Where
Wynstones School, Stroud Road, Whaddon, Gloucester (map)
Description
Geology of the Ordovician Period. 

The last Phanerozoic geological period to be named, after a bitter struggle between Murchison and Sedgwick. Lasting from 
485 to 444Ma ago, this period saw the enormous radiation of new forms of life and the earliest colonisation of the land by primitive plants “The Great Ordovician Biodiversification Event” . The two halves of Britain were separated by the Iapetus Ocean, but both were tectonically extremely active. The supercontinent of Gondwana drifted across the South Pole, possibly triggering a short and unusual (high CO2) glaciation and the second biggest mass extinction of life at the end of the period. As usual there is considerable debate about aspects of this period. 

Starts Mon 16th September  for 10 weeks (not 28th Oct nor 4th Nov nor 2nd Dec), until 9th December   Held at Wynstones School, Stroud Road, Whaddon, Gloucester from 7.30-9.30pm on Mondays.

Did you know that the majority of volcanic eruptions – maybe even 90% – occur under water and of which we are largely unaware? There remains a very great deal we don't know about volcanoes, but many exciting new insights are emerging from ongoing research. This lecture series will encompass the diversity of volcanoes, their functioning and products, together with the nature of eruptions and their attendant problems of predictions plus their ensuing past and present environmental and biological impacts.

Deep Thoughts on Plate Tectonics

Deep Thoughts on Plate Tectonics

THIS ARTICLE gives a very nice summary on current thinking on plate tectonics. In particular it looks at what happens to subducted slabs. There is a wide variety in their fates and this helps explain things such as "Why did the Andes and Tibet wait tens of millions of years after their plates began to converge before they grew tall? And why did the Sea of Japan and the Aegean Sea form rapidly, but only after plates had been plunging under them for tens of millions of years?"

I must admit I did not know that these were questions! But they were for some people and the author thinks that they have been answered. There is a lot in the article and it needs to be read carefully.

I am left with the phrase "Mantle Wind" in my mind.
