Popis: The basic dyke swarms, which have been deformed and metamorphosed, are widespread in the Wudang block. They are geochemicaiiy characterized by the continental tholeiites, and their Sm-Nd isochron age is (782 ±164) Ma. All of these indicate that there was an ancient continental block In the Proterozoic and a rifting occurring on this continental block during ±800 Ma.
