The society is for anyone interested in geology, 
whether beginners or experienced.
This is our 46th year!

We hold monthly talks on a wide range of earth science topics, usually on the 2nd Thursday of the month
. We have several day and weekend field trips a year and sometimes a longer foreign excursion.   

Our talks normally take place at Oaklands College.
Click here to download detailed directions to the venue.

We canít yet resume meetings at Oaklands, so are planning to go ahead with the
September talk on-line via Zoom. 

Details will be emailed to all members, and we will offer assistance
to those who are not familiar with Zoom.

If you have recently changed your email address, please inform the secretary

Please continue to check this web site for the latest information.
Hopefully cancelled events will be rescheduled for a later date.

Meantime, here are some things to keep your geological brain ticking over:

A really interesting talk on Martian geology
This OU/SPA talk describes the (continuing) travels of the NASA Curiosity Rover on the surface of Mars, and its geological findings. 
Click on the Popastro youtube link then select '
SPA meeting, 25 July'.
P.S. The Curiosity rover was built in Stevenage, Hertfordshire!
