岩墙出现在各种各样的地质和构造环境中，通过空间和时间对其进行详细研究对于理解几个地质事件是必不可少的。岩墙被认为是大陆裂谷作用不可分割的一部分，当它们以空间上广泛且大小适中的群体出现时，它们在大陆重建中可以发挥巨大的作用，也有助于识别大型火成岩省(LIP)。众所周知，大陆泛滥玄武岩和主要岩墙群的成因在某种程度上与地幔热柱的抬升有关，地幔热柱可能导致裂谷作用和最终的大陆解体。岩墙标志着地壳的伸展，是地壳稳定事件、超大陆组装和扩散、壳幔相互作用的重要标志，在划定地壳省和破译地壳演化事件方面发挥着重要作用。世界上许多经济矿藏也与各种堤坝有关。这本书将提供有关堤坝各方面的最新信息，重点是堤坝的起源、演化和侵位。
Dykes occur in a wide variety of geological and tectonic settings and their detailed study through space and time is imperative for understanding several geological events. Dykes are believed to be an integral part of continental rifting and when they occur as spatially extensive swarms of adequate size, they can be of immense utility in continental reconstructions and also help to identify Large Igneous Provinces (LIPs). It is known that continental flood basalts and major dyke swarms have their origin related in some way to the up-rise of hot mantle plumes which may lead to rifting and eventual continental break-up. Dykes signify crustal extension and are important indicators of crustal stabilisation events, supercontinental assembly and dispersal, crust-mantle interaction and play a significant role in the delineation of crustal provinces as well as in deciphering crustal evolution events. Many economic mineral deposits of the world are also associated with a variety of dykes. The volume will provide state-of-the-art information on all aspects of dykes with emphasis on the origin, evolution and emplacement of dykes.
