Abstract:
WT5BZ] Volcano eruptions, which are the important landscape in the earth, bring the materials of mantle and crust to the surface of the earth. The eruptions have changed the environment, and also formed the important resources of minerals, geotherm and touring. The authors review the volcano resources from three main aspests. [WT5HZ]

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.

Abstract:
长白山天池火山距今４１０５年以来至少发生过两次大规模喷发。其最近的一次大喷发发生于公元８５０～１０４０年间。估计了这次喷发的喷发物体积和Ｃ１，Ｆ，Ｓ等的释放量。数值模拟表明，该次大喷发对全球气候变化产生过重要影响，最近的地球物理探测结果显示，在该火山下面存在地壳和上地幔双层岩浆房。认为该火山现在仍是一座具潜在灾害性大喷发危险的现代活动火山。

Abstract:
A series of calculation and analyses are developed to estimate Wudalianchi volcanoes hazard. Based on the modern magma chamber conception and examples of active volcanoe abroad, theconsolidation curve and time are inverted by using the theoretical formula of Stefan object, thefragmentation mechanism of Wudalianchi volcano is discussed by the way of SFT (SequentialFragmentation Theory); the crust stability of Wudalianchi volcanoes area is discussed utilizing the structural ratio of crust and mantle; the activity of mantle material in Wudalianchi volcanoes area is discussed utilizing the satellite gravity abnormality of this area, the seepage effect and plug structure ofWudalianceh volcanoes eruption are simulated with the history records of their modern eruqtions. Atlast, volcano hazard is analyzed based on the above discussions in this paper.

Abstract:
This paper deals with the problems pertaining to the methodology of regional volcanic structure,and put forward an approach to the methodology with the study of volcanic structural traces as starting point combined with regional geology,geophysical field and geochemical circumstances.Following such a way the author of this paper made researches on the general features and laws of the volcanic structure of continental facies,expounds the restrictive relationship between the regional horizontal stress field and point vertical stress field under the action of volcanic magma,and analysed the framework structure of volcanic basement.Besides,based upon some geological data of strontium isotope,this paper also disucsses the origin of volcanic substance and its relation with regional geotectonies.

Abstract:
尖山火山位于黑龙江省中北部克山县境内，嫩江支流讷谟尔河的南岸，属于松嫩平原区。由于这一区域基岩出露少，不便于开展1：20万区域地质调查工作，故以往关于尖山火山的资料报道很少。《黑龙江省区域地质志》(黑龙江省地质矿产局，1993)中没有提到该火山，《中国火山》(刘嘉麒，1999)一书中虽提到克山县北兴镇的尖山火山的名称，但不见相关的报道。

Abstract:
Seismic monitoring has been conducted in the area of the Tianchi active volcano during every June to September since 1985.The volcanic seismic events were recorded about 40 times each year from 1985 to 1994.According to our observation data,it was found that the volcanic seismic events obviously increased since July,2002.The times of recorded seismic events increased to 1293 for the year 2002,the seismic events decreased in year 2004,but the released seismic energy remained increasing.This paper evaluated t...

Abstract:
发生于公元946年的长白山天池火山千年大喷发（Millennium Eruption，ME）形成的火山碎屑堆积物体积高达100~172km<sup>3</sup>，并可分为大规模的ME-Ⅰ和小规模的ME-Ⅱ两个喷发阶段。通过对围绕长白山天池火山53个典型露头剖面进行火山地质测量（单元构成、垂向堆积序列和堆积特征），结合筛析法粒度分析、偏光显微镜成分分析，刻画了长白山千年大喷发火山碎屑流堆积物特征，探讨了相和亚相划分，并建立了火山碎屑流搬运和堆积模式。根据火山碎屑的堆积特征，将长白山千年大喷发火山碎屑流堆积分为峡谷充填火山碎屑流相（包括块状峡谷充填亚相和层状峡谷充填亚相）和火山碎屑流冲击扇相（包括扇头亚相和扇体亚相）等两相四亚相。峡谷充填火山碎屑流相主要发育在天池火山锥体周缘距离喷发中心8~23km左右范围内（坡度在15°~60°之间）的火山U型谷中；火山碎屑流冲积扇相主要发育在距离喷发中心23~45km左右范围内，地形相对平缓的熔岩台地处（坡度在5°~15°之间），火山碎屑流的搬运不受地形限制，一般形成较大纵横比扇状堆积。块状峡谷充填亚相和扇体亚相以块状混杂堆积为主要特征，而层状峡谷充填亚相和扇头亚相则以多火山碎屑流单元垂向叠加为主要特征。多单元叠加现象是由搬运过程中火山碎屑流单元发生分离增生作用形成。根据火山碎屑流的最大分布范围和厚度，如果再次发生与长白山千年大喷发类似规模的普林尼式喷发，至少距长白山天池火山喷发中心45km范围内具有巨大的火山碎屑流灾害风险。该研究有利于进一步深入认识长白山千年大喷发火山碎屑流堆积物的空间分布特征和相变规律，对火山碎屑喷发灾害的预防具有指导作用。
