volcanic belt meaning in English
火山带
Examples
- As indonesia lies in the volcanic belt , earthquakes can occur
由于印尼位于火山地带,因此有发生地震的可能。 - Yanliao , ganhang and nanling volcanic belts are not only three important sublatitudinal volcanic belts in eastern china , but important uranium - polymetallic metallogenic belts as well
燕辽火山岩带、赣杭火山岩带及南岭火山岩带,它们不仅是横亘于中国东部的3条重要的近东西向中生代火山岩带,而且也是我国3条重要的铀多金属成矿带。 - The comparison study of the three belts indicates although they are distinct from each other all the three belts show many common features in the aspect of the metallogeny of large - rich vein uranium deposits , i . e : the important metallogenic areas are located above the old crystalline basement ; the paleo - rifting ( taphrogeny ) controls the development of the volcanic belt and at the same time it is favourable metallogenic tectonic environment ; the occurrence of uranium deposit does not depend on the lithology of volcanic rocks ; uranium metallogeny is obviously constrained by deep geologic processes and the connected fault - structural net is the necessary condition for the formation of large - rich uranium deposits
对比研究表明,虽然它们各具特色,就脉型富大铀矿床成矿作用而言,它们又具有较多的共性:重要成矿区的火山喷发皆奠基在古老的结晶基底上;古裂谷(或裂陷)既控制了火山岩带的发育,又是有利的成矿构造背景;铀矿赋存对火山岩的岩性没有明显的选择性;铀成矿的深部控制作用明显;联通的构造网络系统是形成富大铀矿的必要条件。 - This paper describes the regional tectonics , ore deposit geological structure and geochemistry of the ultragiant streltzov uranium deposit in russia and its tectono - magmatic activization ore control , and points out its important practical significance for the metallogenic researches and prospection and exploration for the same type of uranium deposits in the jiangxi - hangzhou volcanic belt of china
摘要文章介绍了俄罗斯超大型斯特列佐夫斯克铀矿床区域构造、矿床地质构造和矿床地球化学特征及其构造岩浆活化控矿规律,指出它对我国赣杭火山带同类型的铀矿床的成矿规律研究和找矿勘探有重要的实际意义。
