While looking for bivalves such as these Pholodomya I picked up around a quarry last year, i was concentrating on the Blisworth Limestone (Great Oolite) which lies just above the Rutland Formation were I also found some crystals. Here’s a photo I took of the exposed crystals of which I like to collect on a return visit this year. Would they be Crystal or could they be Quartz ? Looking east along the line of the fault plane which forms the exposed face of Lincolnshire Limestone on the right. Figure 1. To the left, the downthrown Rutland Formation is capped by Blisworth Limestone, Blisworth Clay and Cornbrash. Where the main fault meets the skyline, the Cornbrash abuts the Blisworth Limestone to form an apparently continuous limestone band, though the fault can be traced from there across the floor of the upper quarry. Figure 2. Diagrammatic profile of the Jurassic succession exposed across the graben zone at this site. Figure 2. Regards, Darren.
