Greenstone granite belts such as those of the archean continued to form in the proterozoic albeit in greatly reduced amounts.
Introduction the qingyuan archaean granite greenstone terrain is located in the northern part of liaoning province covering 8000 km2. Our field investigations combined with available geological maps illustrate the main strain pattern of the study area. The greenstone belt was in truded and separated by younger archaean granites and occurs around older granitic domes. Magnesian komatiites are for the most part absent however.
