| 1. | A batholith has been defined as a huge intrusive mass of granitic rock . 岩基的定义是巨大的花岗石侵入岩体。 |
| 2. | The zone of the intrusions as well as the attitude of the individual bodies harmonizes broadly with the steep northwesterly structure of the surroundings . 侵入岩带和每个侵入岩体的产状都大致与西北向的周围构造协调。 |
| 3. | Irruptive rock body reservoir is one of important volcanic rock reservoirs 摘要侵入岩体油气藏是火成岩油气藏的重要类型之一。 |
| 4. | Traditionally , various subphase belts for irruptive rock body are studied and analyzed by mainly drilling well and coring 传统上对侵入岩体各亚相带的研究和判断,主要通过钻井取心来认识。 |
| 5. | This paper describes the variance correlation between geophysical properties and geochemical properties for tens of intrusive bodies in hebei province , and reaches the conclusion that geophysical exploration methods are not always effective in locating specific mineral deposits 摘要通过对河北省数十个中酸性侵入岩体的地球物理参数与地球化学元素的相关分析,发现这些参数间的相关性是不同的,由此探讨物探异常表达金属矿(矿化)异常的有效性问题。 |
| 6. | Rb - sr whole rock - minerals ages determination indicates that the isochronal ages are 25018 ma and 213 . 09 . 8 ma for suhaitu and wenduerhao intrusion , respectively . the dated isotopic ages demonstrate that the alxa alkaline - rich intrusive rocks belong to indosinian alkaline magma activity . the similarities and differences of the alkaline - rich intrusive rocks distributed in the alxa fault block and those distributed along the northern margin of the north china block and the tarim block are compared and discussed 采用rb - sr法对阿拉善断块有代表性的苏亥图温都尔浩富碱侵入岩体的年进行了测定,分别获得25018 ma和213 . 09 . 8 ma的年值,提供了属于印支期的年代学证据,认为阿拉善断块北缘富碱侵入岩和华北断块北缘燕辽阴山印支期富碱性侵入岩带应该划归同一印支期富碱性侵入岩带。 |
| 7. | Beginning with the minerogenetic theory of mantle plume , the basic geological conditions of this type deposit can be summarized through studying typical copper - nickel sulfide deposits which have close bearing on continental flood basalt . in contrast with high - mg volcanic magmatic activity , it can be found that some intrusive rock bodies have ni - minerogenetic geology condiction . xilaping rocks in binchuan - chenghai region has some basic geological condiction and reflects some extent minerogenetic . all these testify this region has very larger potentiality of finding copper - nickel sulfide deposits 通过对研究区内与峨眉山玄武岩活动有关的高镁火山岩进行研究对比,发现区内与峨眉山玄武岩同期形成某些侵入岩体具有成镍矿(化)的地质条件。研究区内的昔腊坪岩体除了具有这些基本地质条件外,还显示不同程度的矿化,说明该地区作为寻找镍矿的靶区是有很大的潜力。 |
| 8. | This paper is based on practical drilling data of drilled irruptive rock body in western sha segment of huimin depression , rock body subfacies in this phrase and seismic , electric logging features in pyrolysis metamorphic belt are analyzed , so as to summarize a set of practical methods , which identify drilled various subfacies and irruptive rock top and bottom boundary by cuttings log and drill time logging 本文以惠民凹陷西部沙三段已钻遇侵入岩体的实钻资料为依据,尝试性地对沙三段侵入岩体各亚相带及热解触变质带的地震、电测响应特征进行研究,总结出一套较为实用的通过岩屑录井、钻时录井手段识别所钻遇的各亚相带和进行侵入岩体顶、底界卡定方法,现场应用效果很好。 |
