摘 要：Based upon the data of experiment, this paper reveals the characteristics of inclusions in quartz of different genetic types of granitic rocks in southeastern China. Our study shows that granites are derived from a number of ways through magmatism and granitization. As regards their regional distribution granites of the magmatic type prevail in the southeastern coastal belt with largo areas of Mesozoic acidic volcanics, e.g. in eastern Fujian and Zhejiang Provinces, whereas granites formed by granitization including possibly rheomorphism, anatexis and epigenetic frontal granitization occur in the interior part of the continental block of southeastern China, particularly in the Sinian-Caledonian fold zones. As the age of the granites becomes progessively younger, types of inclusions increase, their compositions become more complex and the ore-forming granites are characterized by inclusions with more complex composition, rich in volatile components, and containing a high salinity so that polyphase inclus
