This book offers a high-level summary of shallow magmatic systems (dykes, sills and laccoliths) to support geoscience master and PhD students, scientists and practicing professionals. The product of the LASI (Laccoliths and Sills conference) workshop, it comprises thematic sections written by one or more experts on the respective field. It features reviews concerning the physical properties of magma, geotectonic settings, and the structure of subvolcanic systems, as well as case studies on the best-known systems. The book provides readers a broad and comprehensive understanding of the subvolcanic perspective on pluton growth, which is relevant for mineralogical processes as well as the genesis of mineral deposits.

Christoph Breitkreuz CV

Born in Berlin in 1955, Christoph Breitkreuz studied geology at the TU Berlin. He completed his PhD at the same university in 1982 with a topic on Mesozoic plutons in the Coastal Cordillera of northern Chile. He completed his postdoctoral degree (habilitation) at the TU Berlin in 1986 with a revision of Paleozoic volcanosedimentary successions in northern Chile.

After a research stay at the University of Kansas (1992-1994), Christoph Breitkreuz received a Heisenberg Fellowship (1995-2000), which he spent at the GFZ Potsdam. This was also the start of his research on Late Paleozoic volcanic and subvolcanic systems in central Europe a topic that has formed his research activities ever since. He has been a full professor at the TU Bergakademie Freiberg, where he established a Centre for Volcanic Textures with more than 3000 samples, since 2000.
