以三维地震资料、测井资料为基础，结合区域地质特征，查清了克拉玛依油田八区下乌尔禾组油藏内部近南北向的256断裂带的分布特征，认为256断裂带具有走滑性质，剖面上为花状构造，具有丝带效应、破碎带和火山岩体错断等特征。

From 1999, in the yellow sandpile structure waist deployed the small 22 wells after the testing a newly drilled oil well date productive are 62.47t/d, the daily production were mad 8169m3/d happily attains the high production industrial oil stream, has begun this area exploration and development prologue.

黄沙坨油田是中石油辽河油田公司发现的首例千万吨级规模火山岩油躲，全区累积探明储量2171×104吨，探明含有面积9.3平方公里。1999年在黄沙坨构造腰部部署的小22井试油探知日产油为62.47t/d、日产气8169m3/d喜获产业油流，拉开了该区勘探开发序幕。

Rare elements and REE are mainly enriched in gray-black trachyte and less in other rocks. In addition, schistosity, pyritization, silicification and carbonation in gray-black trachyte are contributed to enrich rare element and REE. It is suggested that alkaline rocks in Hongyang area have the characteristics of subvocanics, and alkaline rocks in Hongyang and Miaoya areas all came from upper mantle and mixed with some substances of crust. Intrusion of alkaline rocks is related to the occurrence, development and evolvement of the deep rupture zone in the areas.

稀土、稀有元素主要富集于灰黑色粗面岩中，而在其他岩石类型中相对较少，同时岩石的片理化、黄铁矿化、硅化和碳酸盐化对稀土、稀有元素有进一步的富集作用；提出了本区的碱性岩组合具有次火山岩相的特征，讨论了本区碱性岩的成因，认为其与湖北庙垭地区的碱性岩可能均来自上地幔，并不同程度地混染了大陆壳的物质成分，其形成时代与断裂构造带的发生、发展和演化基本同步。

Then quantitative and semiquantitative interpretations of volcanic reservoir can be conducted for different types using different rock frame parameters.

由于喷发方式和产出环境不同，火山岩的结构和构造相当复杂，不同岩性具有不同的结构和构造特点。

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.

同时，受热流体活动的影响，热流体对火山碎屑岩具有一定改造作用，如在安山质岩屑凝灰岩中，斜长石绢云母化、火山岩岩屑绿泥石化明显；在凝灰质泥岩中，热流体对围岩中有机碳具有明显的"催熟"加热作用，微量元素则出现异常现象。

Perlite is not a trade name but a generic term for naturally occurring siliceous volcanic rock.

珍珠岩不是一个商标名称，但一般用语，自然发生的硅质火山岩。

The authors suggest that the environment in which subaqueous volcanoes erupt during the deposition of the source rocks is also very good for accumulation of high-quality source rocks.

通过对断陷盆地主力生油岩中普遍存在的基碱性火山岩的分析，认为水下火山喷溢环境是优质生油岩赖以形成的主导因素。

Its main aims include:(1) understanding the magmatic processes of the volcanic rocks and their petrogeneses;(2) discussing the possible enrichment processes induced by subduction of continental slab;(3) providing geochemical constraints on the nature of lithosphere (including the subcontinental lithospheric mantle and lower crust) of the different tectonic units confined by the major faults across the belt; and (4) geochemical comparison of the lithosphere in an attempt to define the possible boundary between the North China and Yangtze Blocks during Mesozoic time.

中文摘要：项目开展了穿越苏鲁造山带南北向晚中生代火山岩及相关火成岩的廊带剖面(包括苏鲁带的胶东、青岛、滁州和下扬子地区的溧水盆地)的地球化学研究，理解各区块晚中生代岩浆作用过程和成因，探索大陆俯冲作用的地幔富集过程以认知各主要断裂围限地区的岩石圈性质；通过对比不同地区的岩石圈性质来限定苏鲁地区华北与扬子陆块的中生代碰撞边界。

The geochemistry, oxygen isotopic composition and biotite composition of the syenite suggest that its rock-forming material was derived from the enriched upper mantle.

渐新世碱性正长岩与中新世钾质火山岩构成了该区碰撞后的构造岩浆组合，是在印度-欧亚板块碰撞引起的岩石圈加厚及高原隆升的基础上，岩石圈拆沉、软流圈上涌导致富集的岩石圈地幔部分熔融所形成的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
