Equipment and Instruments


X-Ray Diffractometry


Element distribution map, showing Mg in a ankaramite (ol + cpx phyric basanite) from the Deccan province. The zoned grain is a pyroxene c. 500µm in length (the highest concentrations being shown in red).


Cameca microprobe


X-ray spectrum observed by means of the energy-dispersive (ED) detection system. The elements present can be identified from the positions of the peaks on the energy scale, enabling rapid mineral phases identification.


One of our 2 Dynamic Mechanical Analysers. One of these is incorporated into an X-ray diffractometer, forming a unique instrument for studying the structural behaviour of crystalline materials as they are subjected to external stress.

International team head to Papua New Guinea to measure volcanic carbon degassing

Sep 01, 2016

An international team of scientists is traveling to the islands of Papua New Guinea this September to study degassing from active volcanoes in remote jungles there. Some of these volcanoes are among the most active on Earth, ejecting a significant proportion of global volcanic gases into the atmosphere.

Mistaken Point - Canada's 10th geological World Heritage Site

Aug 02, 2016

The ancient rugged coastline of Mistaken Point on Newfoundland’s Avalon Peninsula face the winds and waves of the Atlantic Ocean. It can be a difficult place to work, but nevertheless it has been a mecca for geologists for over several decades now.
