Pages : 580

Book Description
Laminated and breccia textures in mineralised veins suggest that host structures have experienced repeated episodes of incremental slip and hydrothermal fluid flow. However, analysis of vein orientation data in terms of fault reactivation theory (Amontons Law) shows that most deposits contain veins that are unfavourably oriented for frictional reactivation. Repeated movement on unfavourably oriented structures may involve dynamic processes of strain refraction due to competency contrasts, the effect of anisotropy in the schist, or localised stress field rotation.

Book Description
La province de Pataz au Nord-Pérou est la plus septentrionale des ceintures paléozoïques d'or, antimoine et tungstène orogéniques (mésothermales) de la Cordillère Orientale des Andes Centrales. Longue de plus de 160 km, elle est connue pour ses veines épigénétiques de quartz aurifères riches en sulfures (ressource : 40 millions d'onces d'or). Les minéralisations, datées à ~314 Ma, sont localisées dans des fractures inverse-décrochantes dextres et d'extension le long des marges et à l'intérieur du batholite de Pataz (329 Ma) et dans les roches métasédimentaires avoisinantes. L'intrusion hôte n'exerce qu'un rôle passif dans leur genèse et fonctionne uniquement comme un réceptacle structural très favorable. La minéralisation est temporellement liée à un stade d'exhumation du bâti et à l'addition d'un flux de chaleur dans une croûte épaissie. Le piégeage de l'or au contact des sulfures microfracturées interviendrait à 5-10 km de profondeur par dilution d'un fluide salin précoce par des eaux superficielles.
