古火山的

This paper sets the boundary of Permian-Triassic on the bottom of ammonoid Hypophiceras Zone or"transitional bed".

对生物在界线附近大规模绝灭的外部原因，本文认为是剧烈的火山喷发和古地理变迁造成的。

Combined with the massage therapy of acupuncture points and meridians and the ancient indian charka energy massage therapy, the therapist puts hot stones on the acupuncture point of the body and the body feels the temperature of the hot stones.this aims to turn on the energy source which can make meridians flexible.

来自纯天然火山玄武岩石，里面蕴藏着大地能量，配合中医药穴位经络按摩法和古印度CHAKRA能量点按疗法，当身体感应热石的温度后，理疗师便将石头放在身体的穴位上以开启活络的能量源；同时沿着全身肌理作滑动和推压动作。

The Late Paleozoic volcanic rocks widely outcropped in the south margin of the Altai Mountains, in which the Middle Devonian Beitashan Formation consists of a series of volcanic-sedimentary rock predominated by intermediate-basic volcanic with rare picrite and ankaramite at the base.

阿尔泰山南缘晚古生代火山岩十分发育，其中中泥盆世北塔山组为一套以中基性火山岩为主的火山－沉积岩系，并且其下部发育少见的苦橄岩和富辉橄玄岩。

The deposit is an adular- and sericite-bearing epitheral gold deposit formed in late Paleozoic volcanic area.

双峰山矿床是晚古生代火山地区典型的冰长石－绢云母型浅成低温热液金矿床。

双峰山矿床是晚古生代火山地区典型的冰长石_绢云母型浅成低温热液金矿床。

In Iceland, civil protection official Agust Gunnar Gylfason said volcanic activity had not particularly intensified, though it does fluctuate throughout the day.

冰岛群众防护部门的官员奥古斯特·衮纳·盖尔发森说，虽然火山每天都在活动，但是强度已经不剧烈了。

Along the low-angle overthrust Early Permian marble and Early Triassic sandy slate were thrust southward over Paleocene-Eocene purplish red conglomerate of the Paleocene-Eocene Fenghuoshan Group and brick-red sandy conglomerate of the Oligocene Yaxicuo Group, forming many klippen of varying scales, and thick fault brecci.

沿低角度逆冲断层，早二叠世大理岩和早三叠世砂板岩自北向南逆冲推覆于古新统—始新统风火山群紫红色砾岩和渐新世砖红色砂砾岩之上，形成大量不同规模的飞来峰；沿主逆冲断层发育厚层断层角砾岩与断层泥，局部形成碳酸盐质糜棱岩。

The mendous thick ore body was formed by sea floor volcanic eruptive sedimentation during the Devonian Period; the stringer ore body by Yanshanian magmatic hydrothermal fluid filling and overprinting. The reduction of old terrigenous detritus and some organic materials has important effect on the late ore fluids.

其中层状矿体为泥盆纪海底火山喷发沉积作用所致，脉状矿体可能来自燕山期岩浆热液充填迭加形成，古大陆碎屑物质和部分有机质的还原对后期成矿流体具有较大的影响作用。

Moreover, these circular structures were also divided into Archaean gneiss dome, intrusive body, buried intrusive body, volcanic center texture, ring fracture and fault, according as their genesis mechanism.

从成因机制上，这些环形构造可划分为太古宙片麻岩穹隆构造、岩浆侵入体、隐伏岩浆侵入体、火山中心机构及环状裂隙或断裂等形成的环形构造。

Since it was discovered in the 18th century buried under 75 feet of solidified ash, the ancient Roman city of Herculaneum has always been overshadowed by Pompeii and Mount Vesuvius.

由于荷克兰姆，这座古罗马城市在18世纪被发现时掩埋在75英尺厚的坚固的火山灰下，多年以来，它一直没有象庞培城和维苏威火山那样为世人所熟知。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
