| 摘 要： | 老挝的岩浆活动分为三个阶段:早期古元古代—早石炭世,中期晚石炭世—中三叠世,晚期晚三叠世—第四纪。早期以中酸性及中基性侵入岩、火山岩为主,中期从超基性—酸性均有出露,晚期则为中酸性侵入岩,火山岩及玄武岩。反映不同构造位置及成因。

| Abstract: | The magmatism in Laos can be divided into 3 stages.The earlier stage is from Palaeoproterozoic to Early Carboniferous.The medium one is from Late Carboniferous to Middle Triassic.The late one is from Late Triassic to Quaternary.The main products of magmatism in the early stage are intermediate-acid,intermediate-basic intrusive rock and volcanite.The products in medium stage include ultrabasic and acid magmatic rocks.The ones in late stage are intermediate-acid intrusive rock,volcanite and basalt.They represent separately the different structural position and genesis. |
