We are very fortunate to have a superb sequence of rocks across the North York Moors. They helped pioneering geologists define the early framework of the science and continue to be used to train the next generations. However the rocks have also been exploited throughout human history to build prosperity and develop the region. The Jurassic section spans some 50 million years of deposit and contains a large variety of ore minerals including ironstone, coal, cement, jet, building stone and alum. Each ore required unique environmental conditions for its formation and the talk will outline what these were and illustrate the resulting mining activity used in extraction.
