Large Igneous Provinces and their Plumbing Systems
Identification of large-volume, short-duration mafic magmatic events of intraplate affinity in both continental and oceanic settings on the Earth and other planets provides invaluable clues for understanding several vital geological issues of current concern. Of particular importance is understanding the assembly and dispersal of supercontinents through Earth's history, dramatic climate change events including mass extinctions, and processes that have produced a wide range of large igneous province (LIP)-related resources, such as Ni–Cu–PGE, Au, U, base metals and petroleum. This volume comprises 21 contributions on the latest developments and new information on LIPs and their plumbing systems and presents methodical studies on different components of LIP plumbing systems. These articles are especially helpful in understanding continental break-up events, regional domal uplift and a variety of metallogenic systems, as well as the temporal and spatial distribution of LIPs, their origin and their likely links to mantle plumes/superplumes.

Geological, geochemical, isotopic and geochronological data for Paleoproterozoic mafic intrusions and dykes indicate that distinct magmatic events dated at c. 2.50, 2.45, 2.40, 2.30, 2.23 and 2.12 Ga can be distinguished in the Belomorian Province, Eastern Fennoscandian Shield. The similarity of Paleoproterozoic magmatic barcodes for the Belomorian Province and the Karelian Craton in the c. 2.5–2.1 Ga interval suggests a neighbouring position of these crustal segments in an Archean continent. Intensive tectonic and metamorphic reworking of mafic intrusions and dykes in the Belomorian Province during the c. 2.0–1.8 Ga Lapland–Kola Orogeny produced differences in mineral assemblages and tectonic position in comparison with the Karelian Craton.
