Welcome to Pegmatite

Pegmatite is the trading name of a geological imaging and analysis partnership managed by Andy Tindle B.Sc., Ph.D, D.Sc., F.MinSoc.

Andy worked for many years at the Open University where he was a scientific officer in the Department of Earth Sciences. His passion is mineralogy and his life has revolved around microscopy and mineral analysis. He was one of the founder members of the Virtual Microscope and the best online casino team who developed a suite of innovative teaching tools for Earth Science courses at the OU. The latest versions of these are now available on-line (www.virtualmicroscope.org). Derivative virtual microscopes are still in use in OU modules, but with password protection.

The success of the best casino book of ra kostenlos spielen ohne anmeldung and interactive hand specimens (object movies) soon spread beyond the Open University and our “tools” are now being used in three other universities (Leeds, Durham, and Trinity College, Dublin). These universities commissioned their own virtual microscopes and we built them using samples from their own teaching collections.

Virtual microscopes have also found a use in museum environments, the first being commissioned for the bicentenary of the birth of Charles Darwin. This collection forms part of the “Darwin the Geologist” exhibition in Sedgwick Museum, Cambridge. We have also worked with Royal Cornwall Museum (Truro) on a “Cornish Mineral Heritage” collection based on historic mineral specimens.

Our scope is not restricted to samples from Earth, as we also have collections of extraterrestrial samples. We worked with the Science & Technology Facilities Council (STFC) to produce an Apollo Moon Rock collection, and later we produced a “Europlanet” collection based on meteorites. We also have a Mars rock collection and are currently working with NASA on other projects.

Pegmatite works closely with the Open University (in particular Professor Simon Kelley) and in partnership is able to offer custom-made virtual microscopes and objects, photographic images, mineral analysis and merchandise. Because many of our images approach gigapixel dimensions we are able to produce large format posters up to 4 metres across. We are interested in working with other partners who wish to either produce and/or retail products that make use of our images.

Additionally, we are also able to offer object movie creation on your own premises as most of our photographic rigs are portable. It’s the closest you can get to allowing your clients to handle your specimens. Try one here. Contact us at andy@pegmatite.co.uk for further details.
