of research results of pertinent references of existing (also finished) research projects of people known to perform research in weathering Below you can find the proposed preliminary structure of databases to be maintained at the IGCP 405 home page (http://www.sci.muni.cz/~sulovsky/igcp405.html):
at ambient conditions i.e. mostly at 298,15 K and 1 bar pressure (particularly those included in weathering reactions): Reference Formula Enthalpy Gibbs function Entropy Mineralogical name
Rate constants of dissolution, disintegration, degradation Rate constants of secondary products formation Conditions Units Rate constant Reaction scheme Rock, mineral Reference (further information can be included)
General references and bibliography Specific references Thermodynamics properties of minerals and related substances Thermodynamic modelling of weathering systems Dynamics of weathering processes Physical processes Chemical processes Global cycles of elements and species Mass balance in weathering systems Ground-, fresh- and sea-water pollution Atmosphere pollution Weathering of lithic building materials Weathering of inorganic materials Conservation of lithic monuments and decorative objects The first version of the references database is accessible here.
· Laboratory facilities - analytical: Bulk methods Microanalytical techniques Surface analysis Physical properties · Laboratory facilities - dissolution experiments etc · Vacancies: Academic positions Post-doctoral fellowships Graduate and postgraduate studentships
The above databases will be made accessible on the Internet as a World Wide Web hypertext documents with the write (submit) option, so that anybody would be able to supply them with data. Aside the "virtual" databases, a "physical" library, i.e. collection of research reports, printed articles and books might arise, serving for circulation of these resources among the project community. The success of this action will depend on the goodwill of authors supplying their works. We are delighted to thank several participants who have already sent their contribution (H. Sverdrup, C. Bűhmann, R. Kűhnel, and others).
The area covered by IGCP 405 thematic definition - Anthropogenic impact on weathering processes - is still very broad. We suggest to focus at the beginning on several, more specific topics. Their eventual selection depends upon the research interests of people who agree to participate in the project - mainly in the sense of sharing their experience, results, facilities, organising skills etc., with the other. In this respect, our key questions are:
Less generally: the initial project proposal distributed was intentionally formulated rather broadly. The actual returns can be classified in several thematic areas. Those with the highest response level are:
