General thematic frame of the WG 1 and WG 3 meetings

“Mineralogy related features and processes common to European Andosols”


 Goals of the meetings 

1. Mineralogical features of European Andosols – Summary of mineralogical data available to date

Identify different mechanisms and time frames of mineral change in European Andosols

2. Identify mechanisms and time frames of organic matter accumulation in European Andosols, included a review lecture on « Mineral control of carbon storage in Andosols » by Dr. Margaret Torn, E. O. Lawrence Berkeley National Laboratory, Center for Isotope Geochemistry, Berkeley, USA

3. Assess the potential of different methodological approaches to contribute to the understanding of pedogenetic trends in European Andosols (IR-Spectroscopy, 27Al and 29Si-NMR-spectroscopy, XRD, TEM, micromorphology, selective dissolution methods, fluoride reactivity, 14C-Radiocarbon dating)


1. Determine the suitability of selective dissolution methods to quantify short range order materials 

 2. Assess Fluoride reactivity – the potential of a forgotten procedure to serve as a single value index of pedogenetic development stage and ecological potential in European Andosols


for both WG1 and WG3:  

1. Discuss and state consequences of the above for classification issues, 

2. Decide on priorities for further action


MC meeting (draft agenda):

1. Approval of the minutes of the last Management Committee Meeting in Ponte Delgada, Azores, Portugal (6 October, 2001).

2. Approval or discussion of the agenda.

3. Report on the rejection of our demand of a 12 months extension of the Action. Discussion and relevant decisions.

4. Report by the Guest Editors on the Geoderma and Catena special issues linked to the International Workshop, Azores, 3-7 October 2001, on « Volcanic soils: properties, processes and land use » we organized.

5. Report on the next WG 1, WG 2, WG 4 and MC meeting in Budapest, Hungary, 19-21 September 2002. Discussion and relevant decisions.

6. Discussion on the planed book on soil resources of European volcanic systems (possible agenda: edition of the book: 2002-2003, printing of the book: 2004): possible Scientific Committee, possible title and chapters, possible edition by either the EEC or/and RALA or a private company such as Elsevier or Springer-Verlag etc)

 7.  Miscellanous
