The basic dyke swarms is a kind of special geologic terrain in continent and continental orogen, which can provide us abundant geodynamic information. The orogenic basement is a exotic or autochthonous block involved in orogenic belt during orogenic processes. The occurrence of basic dyke swarms developed in the basement and its metamorphism as well as its deformation not only give us an evidence of existing ancient block and its cracking in orogen but also provide us an important information to study the tectonic dynamics in orogen processes. Therefore, the comprehensive study on the basic dyke swarms in basement block involved in orogenic belt is of significant to research the formation and development of continental or ogenic belt as well as its dynamical processes.
Key words： Continental or ogenic belt; Basic dyke swarms; Geodynamics.
