1)  volcanic-clastic rock bed association
火山碎屑岩层组合
2)  volcaniclastic rock
火山碎屑岩
1.
Because the type of igneous rock is more,it is very difficult to name and identify,we apply Bayesian discrimination to research lithologic identification in the logging interpretation of volcaniclastic rock.
针对火成岩岩石类型多、测井识别难度大问题,应用贝叶斯判别分析方法对火山碎屑岩测井解释中岩性识别问题进行研究。
2.
The Nibao gold deposit in Guizhou consists of multistory gold ore bodies,each of which is closely associated with the Permian volcaniclastic rocks.
泥堡金矿具多层含矿特征,各层金矿体均与二叠系火山碎屑岩密切相关。
3.
meanwhile,the volcaniclastic rocks were modificated by the thermal fluid activity,for example,sericitization of plagioclase,chloritization of volc.
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。
3)  volcanic fragments
火山岩碎屑
4)  pyroclastic rock
火山碎屑岩
1.
A gold deposit associated with pyroclastic rock and hydrothermal exhalation:Nibao gold deposit in Guizhou Province,China;
一个与火山碎屑岩和热液喷发有关的金矿床——贵州泥堡金矿
2.
Features of igneous rock and pyroclastic rock and their influences on Yaopo coal-bearing formation,Beijing area;
北京地区岩浆岩和火山碎屑岩的特征及其对窑坡煤系的影响
3.

将研究方法应用在海拉尔地区火山碎屑岩岩性识别问题中,取得了很好的效果,岩性解释符合率80%。
5)  pyroclastic rocks
火山碎屑岩
1.
Their potentiality of reservoir is too bad to form oil-producing formation, expect for the pyroclastic rocks.
结果表明,火山岩可划分为火山爆发相、火山喷溢相和次火山相,其储集性能较差,不能形成油层,但火山爆发相和火山喷溢相中的火山碎屑岩和玄武岩的储集性能稍好,对储气可能有效;火山岩周围地层由于受烘烤而出现温度异常,影响了周围泥岩中的有机质成熟度。
2.
The component of pyroclastic rocks are complex.
火山碎屑岩岩性复杂,因此骨架参数难以选择,影响孔隙度的计算效果。
3.
Currently, As the scale and depth continues to increase on oil and gas exploration, in many parts of the world, An increasing number of hydrocarbon reservoirs are found in pyroclastic rocks, for example, there develop a large-scale reservoirs of pyroclastic rocks in Hailar Basin of China, Therefore, people add important attention to research the evaluation about pyroclastic rock reservoir.
由于火山碎屑岩岩性的复杂性,致使其测井响应特征多变,规律性很差,影响了测井解释的符合率。
6)  pyroclastics
火山碎屑物;火山碎屑岩
