My favourite rock images from the posters presented at the 2014 Volcanic and Magmatic Studies Group meeting in Edinburgh:
A. Outcrops
 |
| If Carlsberg made outcrops... a mouth-watering pair of outcrops in the Leka Ophiolite, western Norway (Brian O'Driscoll) |
B. Section images
A difficult choice here, so here are four good ones:
 |
| Large elongate/skeletal olivines in picrite dyke, Skye (Holly Spice) |
 |
| The freshest mantle peridotites you could wish for. They've got garnet+-spinel, and come from alkali-olivine basalts of Pali Aike, in Argentina. Possibly the finest mantle xenoliths in the world? (Eve Rooks) |
 |
| A terrible blurred picture of a beautful rock. These phonolitic tuffs from northern Tanzania have the most lovely zoned Na-rich clinopyroxenes. And they've got hominid footprints on the top of the ash bed. (Anna Balashova) |
 |
| Not an optical microscope image, but fantastic images of great rocks. QemScan images of variolitic picrite from Rum and chrome-spinel layer in anorthosite. (Alan Butcher, FEI) |

An excellent meeting, made even better by
explosive duck-volcano.
