深部控制 meaning in English

deepseated control

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。
