The Asian Clay Research Group was organized through the Nagoya and Seoul meeting in 2010 and 2012. We plan to hold the 3rd meeting in Guangzhou in 2016. Our first participation in The CMS meeting in College Station, Texas, USA (2014) was successful in terms of communicating/collaborating with other clay minerals groups. The purpose of this session, held as part of the Euroclay2015 meeting, is to bring active Asian clay scientists together and promote scientific communication and interaction with the international clay minerals community.

This session focuses on the many geological occurrences of chlorite: from soils to detrital sediments, to sedimentary and diagenetic systems, to hydrothermal alterations and to low- and medium-grade metamorphic rocks, chlorite is everywhere.

Argillaceous media are being considered as potential host rocks for the final, safe disposal of radio-active waste, and/or as major constituent of repository systems in which wastes will be emplaced. In this context clay radwaste scientists examine various argillaceous rocks that are being considered for the underground disposal of radioactive waste, ranging from soft clays to indurated shales.

Clay minerals are present in hydrocarbon source, reservoir and seal rocks and therefore characterizing their presence and properties plays an important role in understanding petroleum systems.  For this session, we call, in particular, on papers that bridge the gap between research and everyday ‘Exploration and Production’ applications and issues - for both conventional and unconventional hydrocarbon accumulations – related to: rock characterization, log response calibration, drilling, diagenesis, reservoir performance, seal integrity, provenance, shale brittleness, fracture properties, org

Natural zeolites are microporous hydrated aluminosilicate minerals having countless technological applications due to their unique physicochemical features such as cation exchange, selective adsorption, molecular sieving, catalysis, etc.  As far as cation exchange is concerned, natural zeolites have been largely investigated for ammonia and heavy-metal removal, although modification of these minerals with long-chain cationic surfactants enhances their adsorption properties towards anions and low polar organic contaminants.

During syn-depositional processes, early and late diagenesis to very-low grade metamorphism (VLGM), alteration and reaction progress with increasing temperature and pressure causes changes in clay-mineral order and clay-mineral association (paragenesis) in sedimentary and volcanic rocks. The evolution of clay minerals with depth during burial and tectonic loading is the principal focus of the symposium.
