Transversal Tectonic Lines in orogenic belts: an update on their role for seismicity, magmatism, and fluid flow
Convener: Andrea Brogi | Co-conveners: Domenico Liotta, Francesco Mirabella, Pietro Paolo Pierantoni
"Transversal Tectonic Lines” (TTL) are regional structures almost orthogonal to the axial trend of the orogenic belts. These lineaments represent tectonic discontinuities which develop in the outer and inner zones of the belts, accompanying the development of the structures, both during collisional and subsequent post-collisional events. In many cases, TTL have been well defined on the basis of satellite and aerial photographs whereas they are not always equally well constrained at outcrop scale. In recent years, several studies were carried out to understand their role in controlling the evolution of the chains and their dismantling. Thus, this session promotes a wrap-up and discussion opportunity, aiming at collecting contributions from different and integrated approaches, on the: (1) geometric and kinematic reconstruction of the “Transversal Tectonic Lines”, with emphasis on their role in controlling the development of thrust systems and sedimentary basins in the collapsed belts; (2) relationships between these structures and seismicity; (3) control exerted on the emplacement of magmatism and volcanism, circulation of hydrothermal fluids and location of base metal ore deposits.
