Jersey Petrology set

On 9 March 2010, Jersey Post will issue a set of five postage stamps featuring petrology specimens found in Jersey.
The oldest rocks in Jersey are the Shale’s which are over 700 million years old. However, the best known rocks in the island are the pink and grey Granites and Diorites. They make up a third of the Island and were formed between 560 and 480 million years ago by molten rock cooling and solidifying deep between the Earth's surface. The specimens featured may all be seen at the MP Shah Gallery at Jersey Heritage's La Hougue Bie Museum, Grouville, Jersey.
