Název v původním jazyce

Lattice preferred orientation of pyrrhotite in a sheeted vein complex of the Mokrsko-West gold deposit of Central Bohemia as investigated by the anisotropy of in-phase and out-of-phase magnetic susceptibility

Popis výsledku v původním jazyce

Preferred orientation of pyrrhotite by crystal lattice in varied mineralized rocks was investigated by means of the anisotropy of magnetic susceptibility. The study area is mineralized contact of Neo-Proterozoic meta-volcanics with Variscan Sa&lt;acute accent&gt;zava tonalite in the Central Bohemia. The contact crops out in the Josef Gallery located in the Mokrsko-West gold deposit. Magnetism of the investigated rocks is dominantly carried by pyrrhotite associated with the Mokrsko-West gold mineralization. In meta-volcanics, pyrrhotite basal planes are parallel to the cleavage and were preferably oriented through recrystallization or neocrystallization in an anisotropic stress field and/or through mechanical reorientation due to ductile deformation of the host rock. In tonalite, pyrrhotite basal planes are parallel to dominating steep joints. This preferred orientation evidently originated through oriented crystallization from mineralizing fluids into microcracks hosting quartz veinlets. Steep to vertical intersections come from differently striking vertical joints hosting mineralizations.
