Geology Trip to Lulworth cove


Louise Norris



On the first day we visited the Etches museum in Kimmeridge. Here we learned about the geological history of the area and the Jurassic Coast as a whole. This included the people who made large discoveries that helped piece together the types of creatures once lived on the coast. After learning about the area and getting our safety gear on, we took a walk down to the bay where we hunted for fossils (mainly ammonites, smallish spiral shaped shells), in the shale that vastly made up the bay. We were fairly successful in finding some small ones, but not too many.


On the second day we visited Portland Quarry and learned about the Portland Stone that was mined there and where it was used. After this, we started our main investigation which consisted of visiting 4 different locations across the shoreline to find out the effects of long term longshore drift on the sediment size and shape. Once we had completed our data collection at all four locations, we visited Lyme Regis which was the hometown for one of the major figures in discovering the local fossils (Mary Annings). Here we learned more about her life, along with local history and geology of this section of the coast, which mainly consisted of a mudstone, shale and limestone. Once we had taken a quick lunch break exploring the sea front cafes and shops, we went fossil hunting again in the same areas that Mary Annings would have been hunting.


On the third and final day, we walked from the youth hostel down to Lulworth cove, where we drew some field sketches of the geological structures of the coast, which showed evidence of folding and faults. Once we finished our sketches, we walked around the bay and filled out the remaining pages of our fieldwork booklets. This required us to answer some questions on the composition of the rock types that made up the cove, along with taking dip and strike readings from the limestone cliffs.
