| Abstract: | Huangling block belongs to the basement complex of the Yangtze platform. The Archean terrain in the northern Huangling block is composed of the trondhjemites with residual adjoining rocks-Wangjiawan group, which was a granite-grenstone terrain,underwent amphibolite facies metamorphism.
These Archean acidic intrusive bodies belong to the alaskite-trondhjemite suites (A-T suites),and ultramafic rocks in the Archean greenston belts belong to the pyroxenic komatiites. |
