Calcite, Hematite, Aragonite and then all the minerals from Caldbeck fells. This one is going to be great fun. So let's start with another specimen In the Sedgwick museum Cambridge (it is a tiny display but has a few good UK specimens)

I was just reading (*) about Norman Thomson's first collecting trip to Roughton Gill Mine, by bicycle, in 1939, when the dumps were "covered in green and blue." He later built a vast collection of minerals from the area, many of which (1700) were donated to the Oxford University Museum of Natural History in 2010.
The diversity of mineral species from this area is very large, many of them green or blue in colour. What interesting material do people have?
Some green pyromorphites to start with.

Thanks Mark.
I'm looking forward to seeing the specimens people have from those hills. Just sticking to blues and greens, there will be plumbogummite, brochantite, philipsburgite, adamite, rosasite, duftite, beudantite and perhaps a few more.

| Plus the famous blue hemimorphites and perhaps some pseudomalachites.

Wow, Knut, an astonishing and beautiful specimen.
An excellent hemimorphite, Ian, and it definitely adds to the interest when a historically well known collector is involved.
Lovely image of Roughton Gill pyromorphites, Jordi.
I just put a group of Caldbeck specimens together for a photo.
