Euroclay 2015 - the quadrennial meeting of the European Clay Groups Association (ECGA) jointly with the annual meeting of The Clay Minerals Society (CMS) and in association with the International Natural Zeolite Association (INZA) and the Geological Society.
To be held at Edinburgh University, Appleton Tower, 5th-10th July 2015.
Organised by The Clay Minerals Group of the Mineralogical Society of Great Britain & Ireland and The Clay Minerals Society.
The scientific program of EUROCLAY 2015 will bring together, in an exciting, leading-edge programme, specialists from different disciplines related to clays and clay minerals. It will consist of technical sessions of both oral and poster presentations with a generous quota of invited speakers who are the leaders in their respective fields. A pre-meeting workshop and mid-meeting field excursions and short course will be integral parts of the scientific program.
A key aim of this conference will be to integrate industrial and academic workers, with sessions which cover both areas arranged around three societal themes where clay research flourishes, namely Energy, Materials, and Environment and Health.
A visit to Edinburgh is one of life's 'must-do' items. As Scotland's capital city, it is the home of geology and is littered with places of interest for the delegate and accompanying person alike.
Workshop
Filling the gaps – from microscopic pore structures to transport properties in shales
The workshop will take place on Sunday 5th of July at the Appleton Tower conference venue.
Organised by Reiner Dohrmann, Chris Greenwell and Thorsten Schaefer under the auspices of the OECD Nuclear Energy Agency (NEA) "Clay Club" in association with Euroclay2015, The Clay Minerals Society and The Geological Society.
The cost is £75, but please note that there is a cost-waiver for students (£0), available on a first-come, first-served basis. This is funded by the 'Clay Club' and the Geological Society.
A wide spectrum of argillaceous media are being considered in Nuclear Energy Agency (NEA) member countries as potential host rocks for the final, safe disposal of radioactive waste, and/or as major constituent of repository systems in which wastes will be emplaced. In this context, the NEA established a Working Group on Argillaceous Media in 1990, informally known as the "Clay Club". The Clay Club examines various argillaceous rocks that are being considered for the underground disposal of radioactive waste, ranging from soft clays to indurated shales.
Additionally, the shale gas and oil community is interested in the characterization of sediments and black shales from the core- to nano-scale, focusing on clay/brine/organic interfaces and understanding how pore space evolves and effects the transport and production potential of the shale system.
Through characterizing fundamental properties such as nano-/micropore connectivity, all the way up to understanding transport and mechanical fracture properties of whole rock units, both communities are studying the geological materials with a shared set of tools, from quantum mechanics computer simulations, through advanced microscopy and diffraction methods, up to triaxial mechanical tests and large-scale transport models.
Very generally speaking, these clay rocks are composed of fine-grained minerals showing pore sizes from < 2nm (micropores) up to > 50nm (macropores). The water flow, solute and gas transport and mechanical properties are largely determined by this microstructure, the spatial arrangement of the minerals and the chemical pore water composition. Examples include anion accessible ("geochemical") porosity and macroscopic membrane effects (chemical osmosis, hyperfiltration), geomechanical properties and the characteristics of two-phase flow properties (relevant for gas transport). In shale oil/gas systems, the role of clay minerals in creating porosity and controlling organic matter distribution is of key interest, as well as larger scale phenomena such as how diagenesis affects the mechanical properties of the shale gas unit. At the current level of knowledge, there is a strong need to improve the nanoscale description of the phenomena observed at a more macroscopic scale. However, based on the scale of individual clay-minerals and pore sizes, for most of the imaging techniques this resolution is a clear challenge.
The workshop, hosted by Euroclay 2015 in Edinburgh, is intended to give, inter alia, a discussion platform on:
- The current state-of-the-art of different spectro- microscopic methods
- New developments addressing the above mentioned knowledge gaps in clays.
- The perception of the interplay between geometry and electrostatics of experimentalists and molecular / Monte Carlo modeling groups providing valuable information on a lattice (1 clay surface; Å) scale.

The deadline for submission of papers and extended abstracts has been extended to 1 March 2015. Papers arising from the invited lectures and extended abstracts of the posters will be published as peer reviewed contributions in a CMS workshop lecture series volume which will be made available on an open-access basis at the time of the workshop. The extended abstracts will be edited by Reiner Dohrmann, and the Invited lectures by Thorsten Schäfer and Chris Greenwell.
The conference will host a workshop follow-on session on Monday 6th July, "From microscopic pore structures to transport properties in shales', for those wishing to make oral presentations and to continue the discussions from the workshop.
Those wishing to submit a smaller (1 page) abstract should register for the follow-on session on Monday: 'From microscopic pore structures to transport properties in shales'. Posters from the workshop and from the follow-on session will both be on display during the day of the workshop and during the follow-on session.
