腾-梁地区岩浆活动频繁,侵入岩出露面积约占39%,喷出岩出露面积约占6%(Xu et al.,2012;Zhu et al.,2015)。岩浆活动主要集中在早古生代寒武纪-奥陶纪、中生代白垩纪和新生代古近纪。目前暂未有确认的前寒武纪岩浆活动的锆石U-Pb年龄发表,从早古生代志留纪到晚古生代二叠纪的近200Ma之间也暂未发现有岩浆活动。腾-梁岩浆岩岩石类型以中酸性花岗岩为主,仅在部分地区发育基性
The magmatic activities in the Teng-Liang area are frequent, with intrusive rocks accounting for about 39% of the exposed area and about 6% of the outcropped rocks (Xu et al., 2012; Zhu et al., 2015). Magmatic activity mainly concentrated in the Early Paleozoic Cambrian - Ordovician, Mesozoic Cretaceous and Paleozoic Paleogene. Up to now, no U-Pb zircon ages have been identified for the Precambrian magmatism. No magma activity has been found between the Early Paleozoic and the Late Paleozoic in the Permian. The Teng-Liang magmatite rock type is mainly medium-acidic granite, which is only developed in some areas
