Description
Four metallogenic stages have been uncovered in the Bondons deposit: 1. metamorphic ante-to syn-S 2 (brannerites); 2. hydrothermal (a) breakdown of brannerites in pitchblende I and anatase; (b) vein paragenesis (pitchblende II, adularia, carbonates); 3, supergene redistribution of previous ores. Thus the deposit fits in a complex polygenetic model, rather than in a simple supergene model at the level of a weathering paleosurface
Abstract (French)
Quatre phases metallogeniques sont demontrees dans le gisement des Bondons: 1. metamorphique, ante a syn S 2 (brannerites); 2. hydrothermales: I, destabilisation des brannerites en pechblende I et anatase; II, parageneses filoniennes (pechblende II, adulaire, carbonates); 3. remaniements supergenes. Le gisement repond donc un modele polygenetique complexe, et non plus a un simple modele de circulation per descensum au niveau d'une paleosurface d'alterationAdditional details
