| Abstract: | This paper introduces the connotation of rapakivi texture and geological and geochemical characteristics of rapakivi granites. Based on a comparison of the granites in the so-called Qinling rapakivi granite belt with typical rapakivi granites in respect to mineralogy, geochemistry and magmatic association, the authos holds that some granitic rocks in the Qinling orogen are not rapakivi granites though they have a rapakivi texture. |
