    Description / Table of Contents: 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.

    Description / Table of Contents: Zusammenfassung Der Ambadungar (Amba Dongar) Alkalikarbonatit-Komplex liegt in der magmatischen Deccan Provinz. Er umfaßt eine Vielzahl von karbonatitischen und alkalischen Gesteinen, die in der Umgebung von Ambadungar aufgeschlossen sind. Die Alkaligesteine sind als Tinguaite, Phonolite und/oder Phononephelinite, Melanephelinite, Syenite und/oder Nephelinsyenite zu klassifizieren, die Karbonatite als Calcio-, bis Ferro- and Silicokarbonatite. Die Anreicherung an LIL-Elementen und Seltenen Erden in den Karbonatiten werden als das Ergebnis der Fraktionierung von Mantelschmelzen, i.e. eines nephelinitisches Magmas, infolge von Nichtmischbarkeit interpretiert. Melanephelinite und/oder Phononephelinite and hohe Gehalte an HFS-Elementen (Ca, Mg, Fe and Mn) in der alkalisch-silikatischen Schmelzfraktion sind ebenfalls das Ergebnis dieser Prozesse. Die La/Lu-Verhältnisse sind typisch für magmatische Karbonatite and variieren zwischen 590 and 1945. Die δ13C Konzentrationen variieren zwischen -2 and -8 %o, die δ18O Werte zwischen 7.7 and 26.8 %0. Während die δ13C Konzentration typisch für primär magmatische Karbonatite ist, ist die δ18O-Anreicherung mit postmagmatischen Prozessen, wie etwa die Interaktion mit meteorischen Wässern and die Reequilibration mit niedrig temperierten wäßrigen Fluiden, erklärbar.
    Notes: Summary The Ambadungar (Amba Dongar) alkaline carbonatite complex is emplaced in the Deccan traps igneous province. A wide range of carbonatites and alkaline rocks are exposed around Ambadungar. The alkaline rocks have been classified as tinguaite, phonolite and/or phononephelinite, melanephelinite, and syenite and/or nepheline syenite whereas carbonatites vary from calcio-carbonatites to ferro- and silicocarbonatites. The enrichment in large-ion lithophile elements (LILE), P, and rare-earth elements (REE) in carbonatites is considered to result from fractionation of a mantle derived magmatic liquid, i.e. nephelinitic magma, by liquid immiscibility which also produced melanephelinite and/or phononephelinite with high field strength elements (HFSE) such as Ca, Mg, Fe, and Mn in the alkaline silicate liquid fraction. The La:Lu ratios of the carbonatites are typical of igneous rocks and vary between 590 and 1945, similar to many known magmatic carbonatites. The δ13C concentration varies between −2 and −8 ‰ whereas δ18O-values vary between 7.7 and 26.8‰. The δ13C concentration is typical of primary igneous carbonatites but δ18O enrichment is thought to be the result of post-magmatic processes such as interaction with meteoric water and re-equilibration with hydrous fluids at low temperatures.

    Description: Several N-trending mafic dykes are exposed in the western Dharwar craton (WDC) and they are thought to be coeval with the ca. 2.22 Ga N- to NNW-trending Kandlamadugu dyke swarm of the eastern Dharwar craton (EDC). Geo- chemical characterization of these dykes is presented here to understand their genetic aspects and likely correlation with their counterpart in the EDC. Petrographic examinations suggest mineralogical and textural variations from dolerite to metadolerite types. Geochemically they are classified either as sub-alkaline tholeiitic basalt or basaltic andesite. Geochemical variations suggest evolution of mantle melt and demonstrate prominent clinopyroxene fractionation, however, minor role of olivine, orthopyroxene and plagioclase fractionation cannot be discarded at initial stages of crystallization. Fractionation trends of trace elements suggest crystallization of accessory phases like ilmenite, apatite and zircon, at later stages. Although observed geochemical nature suggests a little effect of involvement of crust, however, its role in the genesis of the studied mafic dykes cannot be ignored. Conversely, it is suggested that they are derived from a melt generated in a sub-continental lithospheric mantle (SCLM), which was metasomatized during an ancient subduction event before its cratonization. Based on the petrogenetic models of incompatible trace elements, it is inferred that they were likely to be derived from a melt generated by a lower percentage of melting within the garnet or garnet-spinel transition zone. Their connection to the ca. 2.22 Ga large igneous province (LIP) indicates as an integral part of the ca. 2.22 Ga N- to NNW-trending Kandlamadugu dyke swarm of the EDC. The existence of a mantle plume, substantiated by mantle potential temperature (Tp) estimate, is well-supported by higher thermal regime in the upper mantle. Although there is no direct age data available for the studied mafic dykes, however, their geochemical similarities with the ca. 2.22 Ga Kandlamadugu swarm suggest that they are co-genetic and could be linked to the same event. The likely age correlation of the ca. 2.22 Ga Kandlamadugu swarm with mafic dykes of North Atlantic and Superior cratons, support their link with the Superia supercraton.
