1、The French Revolution was a volcanic upheaval in European history。2、Ie seen the stream of lava from a volcano。3、A volcano emits smoke and ashes。4、The volcano poured out molten rock。5、The eruption of volcano makes many people lose their lives。火山概况：火山是常见的自然地貌形态，是由地下熔融物质及其携带的固体碎屑冲出地表后堆积形成的山体。火山主要形成在板块交界处，构成了四大火山带。火山可分为活火山，死火山和休眠火山，是炽热地心的窗口、地球上最具爆发性的力量，爆发时能喷出多种物质，主要物质为火山灰。
Torricelli Daerbute fault zone north of Xinjiang formation predecessors established the Lower Carboniferous package Couto Group and the Commission on the Carboniferous too Le Dracula group， with the attribution of North Junggar formation formation of the district Mayi formation The profiles measured by sedimentary rock， based on formation， rock characteristics， in the region compared to their predecessors here that the formation of the order is Ancient map packets identified in the group was placed under the Lower C Bao ancient group plans for a major deep-sea - half of the deep gray and gray-black TLC tuffaceous siltstone， shale tuffaceous， with gray green， with thin gray-tuff interbedded Lithologic main debris containing fine sand silt， tuffaceous sandstone， with silt， mud cherts， cherts， such as Shen The overall environment is relatively calm and stable， for deep-sea - a half deep-sea Le Dracula is the main group for the ash， glaucum， purplish red basalt and andesite， fine-grained tuff， crystal-tuff debris， ash-tuff， tuffaceous siltstone， tuffaceous silty mudstone uneven beds， rocks folder jasper ， Ansan porphyrite and long-sandstone and Analysis should be the reinstatement of the environment， there are intermittent eruption of deep-sea sediment Key words: Pack ancient map; too Le Dracula groups: sedimentary environment; Xinjiang Torricelli; Daerbute fault
Soil grain grade composition of soil physical and chemical properties of influence， this is the method of using BiChongJi southwest area into several rock soil (purple soil， lime soil， volcanic dust) grain Some conclusions:Southwest area into rock (soil， lime， purple soil and volcanic dust particles in the sand， which accounts for more than viscous grain powder， small 2 the same soil layer， due to the different leaching deposition etc， on the effect of soil layer of grain composition class there are differences of sand soil， black limestone and clay content with the increase of depth and And the sand and volcanic ashes viscous grain content decreased with 3 the soil due to different locations eluviation weathering， the influence of human activity and the degree of different level， the soil grain composition there is some 4 different soil layer， due to the different soil of rock， soil contains sand development of sandstone and mudstone limestone， development of viscous grain 5 the same soil types， different sub-types of soil particle composition is different， but the trend is Keywords: rock into the soil， The soil profile， Grain grade， Determination
