摘要

在地球和其他行星的大陆和海洋环境中识别大体积、短时间的板内亲和性岩浆事件,为理解当前关注的几个重要地质问题提供了宝贵的线索。特别重要的是了解地球历史上超级大陆的聚集和分散,包括大规模灭绝在内的剧烈气候变化事件,以及产生大量与大火成岩省(LIP)相关的资源(如Ni-Cu-PGE, Au, U,贱金属和石油)的过程。本卷介绍了在前寒武纪和显生宙的短粒岩的时空分布、它们的起源、基性岩脉群的管道系统、基底省和层状侵入体,以及与地幔柱/超柱事件、超大陆重建和相关成矿作用的联系等方面的一些最新进展和新信息。

An overview of the plumbing systems of large igneous provinces and their significance
Abstract 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 current volume presents some of the latest developments and new information on the temporal and spatial distribution of LIPs in both the Precambrian and Phanerozoic, their origin, the plumbing system of mafic dyke swarms, sill provinces and layered intrusions, and links to mantle plume/superplume events, supercontinent reconstructions and associated metallogeny.
