Certainly not Cornish.

Hi Tom

M Thomas is definitely Morrison Thomas. I knew him well many years ago, we used to go up to Weardale buying rocks off the miners and collected together quite a bit. And yes, he did sell his ...

That's interesting Colin. Will check the number of mine next time I manage to get home, probably in a couple of weeks, just in case it's incorrect.

Otherwise, I have no idea whether Col William's ...

Tucson - so soon.

Start my trip on Friday - see you all over there

In many years of collecting British minerals, I have never seen anything remotely similar from Cumbria (or elsewhere). Can't even suggest a possible UK location, perhaps someone else may be able to th ...

Well done roy. look forward to seeing it

A Merehead calcite - globular aggregates to 8mm formed of minute manganoan calcite crystals.

A 4mm anatase from the brookite type locality of Twll Maen Grisial in north Wales. Collected in 1984, I've spent a bit of time here over the years.

Minute dickite crystals richly covering dolomite. From Pant-y-Gaseg Mine, Anglesey, the type-locality.

Tabular, pale blue baryte crystals to 35mm on calcite, exceptional for the locality and for South Wales. Collected by David Lloyd and Richard Barstow May 1981. Ex Richard Barstow collection.

Jealous Mike, I never found any fluorite there.

Here is a bustamite, collected 1983, from the British Rail quarry at Meldon.

Something of a Cornish rarity. Light green microcrystaline arthurite (type locality) and dark green olivenite. Collected from material around the collar of Hitchen's Shaft in the 1980s.

Arthurite ...

Fluorite from Frazer's Hush showing an unusual purple exterior over a pale green inner core.

Another Hamstead Farm Quarry calcite, this one with crystals to 20mm coated with pyrite, and with a second generation of calcite crystals partially overgrowing them. Specimen collected in 1986.

A zoned "horse-tooth" siderite from Wh Maudlin. A Cornish classic - Peter Embery, the late curator at the Natural History Museum in London reckoned that these all came from a single vug abou ...
