腾冲新生代火山分布特征

DISTRIBUTION CHARACTERISTICS OF TENGCHONG VOLCANO IN THE CENOZOIC ERA

通过实地考察和资料对比，综合前人研究成果，最终得出腾冲地区新生代火山有６８座，并给出各个火山主要分布特征。同时根据火山喷发类型、岩性、时代、地域等相关性，腾冲火山区新生代火山划分为７个火山群：１鸦鸟山———大黑山火山群；２大团山———黑龙湾火山群；３马站火山群；４打鹰山———马鞍山火山群；５余家大山———大六冲火山群；６来凤山———三益村火山群；７大呼山———照壁山火山群。腾冲新生代火山分布具有数量多、面积广、类型全、活动具有多期性等特征。

Through survey in site and comparison of data, synthesizing study achievements of forefathers, finally, 64 volcanoes in the Cenozoic Era in Tengchong area have been found, further, the distribution characteristics of individual volcano has been described. meanwhile, based on eruption type, rock property, times, region and their interrelations, volcanoes in the Cenozoic Era in Tengchong area have been divided into 7 volcano swarms:1.Wuyashan Daheishan swarms; 2.Datuanshan Heilongwan swarms; 3.Mazhan swarms; 4.Dayingshan Ma'anshan swarms; 5.Yujiadashan Daliuchong swarms; 6.Laifengshan Sanyicun swarms; 7.Dahushan Zhaobishan swarms. The volcanoes in Cenozoic Era of Tengchong have features of large number, wide area, multi types, multi periods of activities.
