黑龙江省莲花山第四纪火山
Lianhuashan Quaternary volcano in Heilongjiang Province
摘要
Abstract
This paper discusses the volcanic landscape, eruption time, petrology, petrochemistry, structure and economic geology of Lianhuashan volcano in Heilongjiang Province. According to the isotopic dating of Shihlunites and stratigraphie sequence of the Quaternary strata of Lianhuashanvolcano, its eruption time is ascertained as Pleistocene. The obtained data of rare earth elements, trace elements, mantle-source inclu- sions and meagacrysts show that the petrology and petrochemistry of Lianhuashan volcano are similar to those of Wudalianchi volcano, with a slight difference between them. The authors considered that the Lianhuashan and Jianshan volcanoes are the southwestward extended part of Wudalianchi volcano. In a broad sense, Wudalianchi volcanic group includes Wudalianchi,Lianhuashan and Jianshan volcanoes, alto- gether consisting of 21 volcanic cones.关键词
