我国著名的活火山之一,东北的五大莲池火山群以其保存完好的熔岩地貌,甘美爽口的矿泉和优雅秀丽的景色为世人所向往,具独特的富钾火山熔岩更吸引岩石工作者的关注。本文就五大莲池及毗邻地区所产的一套富钾火山熔岩的归属问题给出一管之见,以期引起人们的重视和讨论。 (一) 由于环太平洋火山带的作用,东北地区新生代火山岩十分发育。据现有资料,产于辽宁宽甸、吉林敦化、黑龙江镜泊湖以及大兴安岭的新生代火山岩,基本为碧玄岩——碱性橄榄玄武岩;在长白山天池,岩石组合为橄榄玄武岩——碱性粗面岩——碱流 One of the famous active volcanoes in Northeast China, the five great Lianchi volcanoes in the northeast are world-famous for its well-preserved lava landscape, refreshing springs and elegant scenery. The unique volcanic lava with rich potassium is more attractive to rock workers attention. This article gives a comment on the ownership of a set of potassium-rich volcanic lava produced by the five major Lotus Ponds and adjacent areas in order to arouse people’s attention and discussion. (A) Cenozoic volcanic rocks in Northeast China are well developed due to the role of the Pacific Rim. According to the existing data, it is produced in the Cenozoic volcanic rocks in Kuandian, Jilin, Dunhua, Jingpo Lake in Heilongjiang and Daxinganling. The basalt is basalt-alkaline olivine basalt. In the Changbaishan Tianchi, the rock assemblage is olivine basal-alkaline Rough rock - alkali flow
