本文探讨了华南地区火山岩型或花岗岩型富铀矿，与岩浆旋回晚期的构造－岩浆活动的关系。火山岩型富铀矿离不开大规模火山活动的晚期次火山活动；而花岗岩型富铀矿，则与主侵入晚期的中细粒、不等粒小岩体密切相关。经过长期研究，根据岩浆作用性质，将这套独具特色并与富铀矿的形成息息相关的岩石，定为花岗质潜火山杂岩 This paper discusses the relationship between volcanic or granitic uranium-rich uranium deposits in southern China and the tectono-magmatic activity in the late stage of magmatic cycle. Volcanic rock-rich uranium deposits are inseparable from the late subvolcanic activities of large-scale volcanic activity. Granitic uranium-rich uranium deposits are closely related to medium-fine and unequal small-sized rock masses in the late stage of main invasion. After a long period of studies, according to the nature of the magmatism, this unique set of rocks associated with the formation of uranium-rich uranium deposits has been designated as granitic subduction volcanic complex
