Rocks rock

image.jpg  Hi I’m new to mineral hunting and have just been to the beach near Hornsea in East Yorkshire. My husband and I have found some amazing stones today but I think some of them are Rhomb porphyry? I would appreciate if anyone could help identify them. 

Thanks

Hi
Assume these have been brought into the area by glaciers. Water worn pebbles of maybe.......top left Breccia, top right Bioclastic limestone (broken shells) and yes it does look like rhomb porphyry but couldn't say for sure without a thin section and analysis with a petrological microscope. If it is presumably it's Norwegian...

Thanks for the reply and the information, much appreciated. I am finding this new hobby fascinating. Here are some of my crystals I found near an old lead mine in swaledale  image.jpg  image.jpg  image.jpg

Assume those crystals were the unwanted part of the mineral vein that the lead ore (Galena?) was found in. Have you figured out what they are?

Maybe barite or calcite at the top? It’s quite heavy so maybe some lead inside as well. I broke the big white one open as it was intriguing but I haven’t found any pictures online of anything similar. I’m wondering if it’s quartz, hope it’s not radioactive!!
