Abstract: This paper tries to review dike swarms less reported in the world and describe their tectonic and metallogenic implications, defining them as the wide spectrum dike swarms (WSDS). On such a basis, the authors have reached some conclusions:①the WSDS is a specific igneous suite, whose compositional diversity is induced mainly by its origin. Thus the WSDS differs from the other known igneous suites;②the WSDS's direct tectonic meaning is the lithosphere delamination;③Because the producing process of the WSDS needs the active involvement of the deep fluids, the WSDS is the targeting criterion in search for ore deposits;④the magma system is a complex dynamic system. Under the framework of ideal system, many signatures recognized from the WSDS are contradicted. However, these signatures can be integrated under the framework of the complex system;⑤the intraplate orogen is a specific type of orogen. The orogenesis can not be directly related to the tectonic force from the plate boundaries. WSDS applies equally to intraplate orogen and plate boundary orogen.
