陆上火山碎屑流沉积剖面的研究

A Study of Sedimentary Section of the Subaerial Pyroclastic Flows

如同火山碎屑流般凶恶，喷发进入大气层的火山灰甚至会造成更深远的影响。

As bad as the pyroclastic flows are , the ash injected into the atmosphere can have even more far-reaching consequences .

笔者对滦平地区火山碎屑流冷却单元进行了深入的研究，划分出12个冷却单元。

The author deeply studied cooling unit of pyroclastic flow in Luanping area and divided the volcanic rock into 12 cooling units .

美国纽约州立大学布法罗分校火山碎屑流和泥石流数学模型研究近况

Research on the Numerical Model of Pyroclastic Flow and Debris Flow in the State University of New York at Buffalo , USA

分析结果表明，火山碎屑流堆积分选差，伴生的灰云浪堆积分选性好。

The result shows that the pyroclastic flow deposits are poorly sorted and the ash cloud surge deposits accompanied with pyroclastic flow are well sorted .

几天后，真正的爆发开始了。附近地区受到汹涌的火山碎屑流和火山灰泥流的侵袭，堆积起的火山灰厚度超过十英尺。

A few days later the main eruption occurred and the nearby land was subject to fiery pyroclastic flows , swift-moving lahars and over 10 inches of ash-fall .

其中对人类生命财产构成严重威胁的火山灾害有熔岩流、火山碎屑流、火山泥流和火山海啸。

Lava flows , pyroclastic flows , lahars and volcanic tsunamis are the major hazards that threaten the life and property of the people .

许多人的生命已经丧失由于火山频繁喷发，这是伴随着高速的火山碎屑流和泥流所谓的火山泥流。

Many lives have been lost to the volcano 's frequent eruptions , which are accompanied by high-speed pyroclastic flows and mudflows called lahars .

园池期火山喷发模式为：普林尼式喷发柱-火山碎屑流。

The eruptive pattern of the Yuanchi phase is from Plinian column ( the Yuanchi pumice and ash fall deposits )→ pyroclastic flow ( the Bingchang pyroclastic flow deposits ) .

通过对研究区火山产物分析，推测未来主要火山灾害由火山喷发空降碎屑物、火山碎屑涌流、熔岩流、火山喷发气体造成。

Based on the analysis of volcanic products , it is inferred that the future probable volcanic hazards would be caused by descending pyroclasts , pyroclastic outpouring flows , lava flows and gases from volcanic eruptions .

火山岩15亚相中能够成为Ⅰ类储层的通常仅4种：火山颈，热碎屑流，喷溢相上部和侵出相内带亚相。

Only four of the 15 volcanic sub-facies can form high-quality volcanic reservoirs , which include volcanic neck , pyroclastic-bearing lava flow , upper effusive and inner extrusive sub-facies .

维苏威火山的喷发十分剧烈，持续两天。炽热气体和火山灰混合在一起，形成了一种被称为火山碎屑流的罕见灾害。

The eruption of Vesuvius was intense and strong , lasting for two days and forming a relatively rare , but inescapable flow of super-heated gas and ash known as a pyroclastic flow .
