The mine zone is sandwiched between an overlying block of flows, pillow lavas and minor pyroclastics, and underlying agglomerates, tuffs, and more massive diabase bodies.
含礦帶夾在上覆的巖流、枕狀巖流和少量火山碎屑巖塊與下伏的集塊巖、凝灰巖和塊狀輝綠巖體之間。As bad as the pyroclastic flows are, the ash injected into the atmosphere can have even more far - reaching consequences
如同火山碎屑流般兇惡,噴發進入大氣層的火山灰甚至會造成更深遠的影響。As the land above the magma chamber collapses, immense gray clouds called pyroclastic flows burst out horizontally all around the caldera
當巖漿庫上方的陸地崩陷,稱為火山碎屑流的巨大灰色雲霧,會突然由火山臼的周圍向外水平散開。The upper cretaceous jingzhushan formation in the biru basin, xizang consists of a succession of coarse - grained elastic rocks in the alluvial fan - fan delta depositional system, intercalated with intermediate - acidic volcanic rocks including dacite, andesite, quartz trachyandesite and rhyolite
摘要上白堊統競柱山組為一套沖積扇扇三角洲沉積體系的粗碎屑巖,間夾由英安巖、安山巖、石英粗安巖和流紋巖組成的中酸性火山巖。The sedimentary facies show a depositional evolution from the deep - water sediments through shallow - water sediments to the continental sediments, including alluvial fan, river, lake, delta ( tide - dominated ), barrier coast, shallow sea, deep sea and volcanic debris flow deposits
在沉積相上,經歷了從深水沉積到淺水直至陸相沉積的演變,發育有沖積扇、河流、湖泊、三角洲(潮汐) 、障壁海岸、淺海、深海和火山碎屑流沉積。The main characters of the thermal fluid activity are recognized as follow : many types and stages of veins are widely developed ; vitrinite reflectivity of different areas varies apparently with the depth ; there was a high temperature field during the formation of the thermal fluid, meanwhile, the volcaniclastic rocks were modificated by the thermal fluid activity, for example, sericitization of plagioclase, chloritization of volcanic detritus in andesitic detris tuff ; in the tufaceous mud, the thermal fluid activity accelerates " maturating " of the organic carbon by heating ; and the trace elements show an anomaly in the wall rocks
同時,受熱流體活動的影響,熱流體對火山碎屑巖具有一定改造作用,如在安山質巖屑凝灰巖中,斜長石絹雲母化、火山巖巖屑綠泥石化明顯;在凝灰質泥巖中,熱流體對圍巖中有機碳具有明顯的「催熟」加熱作用,微量元素則出現異常現象。The most powerful plume in nature is volcanic plume, which is formed by ejection of mixture of pyroclasts and volcanic gases in to the air from volcanic vent
世界上中最壯現的羽流現象是由爆炸性火山噴發的各種火山氣體、細粒的火山噴發碎屑物所組成的火山噴發柱,也就是我們俗稱的火山蘑菇雲。During my master " degree investigation, i mainly focused on the coarse - grain stratigraphy within mesozoic basins in chengde and pingquan districts, the eastern yanshan, and did systemic provenance analysis and paleo - current direction measurement and studied the relationship among basin evolution, volcanism and tectonism. then i summarized the mesozoic basin development and the coupling characters of basin and mountain. the evolution of basin and mountain in this area can be divided into several stages : the stage of compression uplift and flexural basin during the triassic through the early jurassic, the stage of structural compression - volcanism and foreland basin during the middle and late jurassic and the stage of rift basin in the cretaceous
在野外典型路線調查的基礎上,對燕山地區東段承德、平泉地區的中生代盆地中發育的粗碎屑沉積層,進行了系統的物源分析與古流測定,並在此基礎上重點剖析了盆地的發育、火山活動、構造變動三者之間的關系,總結了本區中生代盆地發育規律及盆山耦合特徵,並將盆山演化劃分為:三疊紀?早侏羅紀的構造擠壓隆升與撓曲盆地發育階段階段,中晚侏羅紀的構造擠壓?火山活動與類前陸盆地發育階段,早白堊世的拉張斷陷盆地發育階段。These flows are an intermediate stage between lava and ash, so they move extremely rapidly ? up to 400 kilometers an hour, some sources say ; cars and even small airplanes would have no chance of outrunning them
這些碎屑流是巖漿與火山灰的中間物質,因此移動極為迅速,有些時速可達到400公里,所以就算是開汽車甚至是搭小型飛機,可能都逃不出它的魔掌。Through these studies, preliminary results and understandings have been gained as follows : 1 ) propose a reverse - appraisal method that is more reliable based on imaging well log data to classify the lava flow orientations of volcanic rock facies, integrating with lava - debris thickness ratio
通過研究,初步獲得的成果和認識如下: 1提出了依據成像測井資料,劃分火山巖巖相的熔巖流向反推法,結合火山熔巖與碎屑巖厚度比法,劃分結果更可靠。分享友人
