Structural evolution and settings of orogenic gold and intrusion-related gold deposits in the central part of the Bohemian Massif, Czech Republic
2013
Abstract
Orogenic gold and intrusion-related gold deposits in the central part of the Bohemian Massif formed under similar tectonic conditions, in local extension settings within a regional tectonic zone along the boundary between two crustal blocks. Older age (347-341 Ma) and greater depths (15-11 km) characterize the intrusion-related gold deposits with respect to the group of orogenic-gold deposits (340-337 Ma and 9-7.5 km).
Formation of both types of gold deposits occurred during the uplift of the tectonic block with the Central Bohemian Plutonic Complex.
