A close up of Puddingstone, a conglomerate, showing the tightly packed flint pebbles cemented together with a matrix of silica quartz. Not confined to Hertfordshire, but strays across the borders to Buckinghamshire, Essex etc. The slideshow above shows some of the variety in the size of the pebbles. In its time it has been used as a building stone, for grinding corn and purely as decoration, as can be appreciated in the pictures above.

The Society has monthly meetings with guest speakers + field trips in London, Hertfordshire and further afield. We also visit museums; hold an annual ‘Mineral, Gem and Fossil Show’; have a Members Evening (with members giving talks), offer free geology courses and even have competitions.
In addition we have a newsletter six times a year and in 2015 celebrated our 50th anniversary! If you would like to join our society please see our secretary’s details under “Contacts”.
