Objective
MINERALIZED ZONES IN GRANITIC ROCKS WHICH HAVE BEEN INFLUENCED BY HOT WASTE (HYDROTHERMAL ACTIVITY) OVER LONG GEOLOGIC PERIODS MAY BE CONSIDERED AS USEFUL NATURAL ANALOGUES OF THE CONDITIONS OCCURRING AROUND A HEAT-PRODUCING REPOSITORY IN GRANITE. STUDY OF THESE ZONES GIVES VALUABLE INFORMATION ABOUT THE MIGRATION AND RETENTION OF ELEMENTS ANALOGOUS TO THE RADIONUCLIDES PRESENT IN THE REPOSITORY.
DEVELOPMENT OF RESEARCH ON ONE OR MORE SITES OF FORMER HYDROTHERMAL ACTIVITY IN A GRANITE ENVIRONMENT WILLENABLE AN APPROACH TO THE PROBLEMS OF MIGRATION AND RETENTION OF ELEMENTS SUCH AS THE RARE EARTHS, URANIUM AND THORIUM WHICH ARE THEMSELVES ANALOGOUS TO THE RADIONUCLIDES IN THEIR GEOCHEMICAL BEHAVIOUR. THE TIME SCALE WILL BE THAT OF THE GEOLOGIC ENVIRONMENT OF 0.1 TO 1 MILLION YEARS. THE VOLUMES CONSIDERED WILL TAKE INTO ACCOUNT THE FAR FIELD (PERVASIVE ALTERATION) AND NEAR FIELD (VEIN ALTERATION) PHENOMENA. THE FINAL AIMS OF THIS PROGRAMME ARE :
1. TO DEFINE THE PHYSICOCHEMICAL CONDITIONS OF THE ALTERATION EXAMINED AND THE MINERALOGICAL CARRIERS OF THE ELEMENTS ANALOGOUS TO THE RADIONUCLIDES.
2. TO TEST ON EXISTING PROGRAMMES (PATH) OR ON THOSE BEING DEVELOPED, THE DATA SUPPLIED BY THE DIRECT APPROACH (VALIDATION OF THERMODYNAMIC PARAMETERS, ASSESSMENT OF THE REACTION KEACTION KINETICS ON NATURAL EXAMPLES)
B.1. PETROGRAPHIC AND MINERALOGICAL INVESTIGATION OF THE VARIOUS EVENTS WHICH HAVE AFFECTED THE SYSTEM.
B.2. ANALYSIS OF THE ANALOGUE ELEMENT CARRIERS IN TWO PARTS :
B.2.1. SEPARATION OF THE PRIMARY AND SECONDARY PHASES DEVELOPED BY THE ALTERATION AND QUANTITATIVE ANALYSIS OF THE ANALOGUE ELEMENTS IN THE SEPARATED PHASES AND IN ROCK SAMPLES :
B.2.2. LOCATION OF ANALOGUE ELEMENTS BY NUCLEAR METHODS. FROM THESE DATA THE MASS BALANCE AND THE DISTRIBUTION AND MOBILITY OF THE ANALOGUE ELEMENTS DURING THE PALAEOALTERATION WILL BE ESTABLISHED.
B.3. AN INDIRECT APPROACH BY USING MASS TRANSFER CODES ON MAJOR TRACE AND ANALOGUE ELEMENTS TO MOBILIZE THE GEOCHEMICAL BEHAVIOUR OF THE ALTERATION SYSTEMS.

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.
