THE IMPROVEMENT OF EXISTING DATABASES BY THE INTRODUCTION OF OBJECTIVE CRITERIA FOR THE PROBABILITY OF FORMATION OF SOLID PHASES. A FIRST STEP TOWARDS AN "EXPERT SYSTEM".

Objective

IN THE PREDICTION OF THE EXTENT OF MIGRATION OF POLLUTANTS INTO THE ENVIRONMENTS THE CONFIDENCE TO THE CALCULATIONS IS PRIMARILY DEPENDENT ON THE VALIDITY OF THE MODEL USED, I.E. THE GEOCHEMICAL CALCULATIONS AND THE HANDLING OF THE CONVECTION DISPERSION PHENOMENA. IN GEOCHEMICAL CALCULATIONS IT IS USUAL PRACTICE TO ASSUME THAT LOCAL EQUILIBRIA ARE ESTABLISHED. THIS MAY WELL BE TRUE IN MANY CASES, BUT THAT DOES NOT AUTOMATICALLY MEAN THAT OVERALL CHEMICAL EQUILIBRIUM IS PREVAILING IN A FORMATION.
APART FROM THESE DIFFICULT CONSIDERATIONS, THE GEOCHEMICAL CALCULATIONS MAY BE IN ERROR OR SCREWED BECAUSE THE THERMODYNAMIC DATA USED ARE INCORRECT OR INTERNALLY INCONSISTENT.
THE PRESENT PROJECT HAS THE FOLLOWING GOAL: TO IMPROVE THE GEOCHEMICAL DATABASES, SUCH THAT THEY MAY BE USED TO HANDLE A WIDER RANGE OF PROBLEMS.

1. TO DEVELOP A DATABASE MANAGEMENT SYSTEM WHICH CAN BE USED TO MAKE AVAILABLE DATA INTERNALLY CONSISTENT, I.E. TO REFER TO THE SAME SET OF FUNDAMENTAL STANDARD DATA.
2. TO REVIEW AND COMPARE THE MOST WIDELY USED DATABASES.
3. TO CLASSIFY MINERALS ACCORDING TO THEIR "PROBABILITY OF FORMATION" OR OTHER CRITERIA RELATING TO THIS.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Data not available

Call for proposal

Procedure for inviting applicants to submit project proposals, with the aim of receiving EU funding.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
