Introduction to the special issue on convergent plate margin dynamics

Convergent plate margins are arguably the most complicated and dynamic plate boundaries on Earth and have been the subject of many investigations and discussions since the advent of plate tectonic theory. Due to the varied, heterogeneous and complex structure of convergent plate margins, which arises from the multiple geological, physical and chemical processes operating at these zones, and because the largest portion of the system is hidden deep beneath the surface, much remains enigmatic and unknown about these important plate tectonic features. As such, numerous fundamental problems still need to be addressed. The papers presented in this special issue provide many new insights into a variety of geological, geophysical and geodynamical problems.
