Last week, members of the Southern Branch of the Russell Society came to visit the Museum. They especially wanted to see some of the minerals in our collection that came from the South Coast of England. The Russell Society, in case you are wondering, runs lectures, museum visits and fieldtrips for people who enjoy finding out about minerals. It is named after Sir Arthur Russell, one of Britain’s most gifted amateur mineralogists. I’m a member and so is one of our volunteers, Jane Randle.
Now, Jane and I know the Russell Society folk are a very knowledgeable lot, so we put our heads together a devised a challenge for them. We got out from the stores a whole lot of interesting minerals from quarries, mines, beaches and cliff exposures all along the coast from Kent round to south Devon, and laid them out in a random way. Then came the fun bit; we took away all the labels!
The task was to work as a team and organise the minerals according to where they were found, from west to east. Easy? Well, that depends on how good you are at recognising the different kinds of minerals and where they come from.
One of the fun things about minerals is that each kind – calcite, quartz, gypsum, etc, – can look very different according to where it is found. Some are very easy to recognise but some are not. After much debate, looking at maps, and rearrangement of specimens came the moment of truth as Jane and I put the labels back with their specimens, and everyone could see whether or not they were right.
Our Russell Society folk certainly showed they know their local minerals! They recognised the little round masses of baryte crystals from the Isle of Sheppey, large transparent gypsum crystals from Battle, powdery white masses of aluminite from Newhaven, rare blue vivianite crystals from near Southampton, sparkling pointed crystals of calcite from Charmouth, branching crystals of real gold from near Torquay, and many more. Others did elude them, and came from surprising places. Our beautiful polished slices of fossil sponges, for example, came from pebbles collected on Brighton beach in the 19th century!
