晶鈾礦 的英文怎麼說
中文拼音 [jīngyóukuàng]
晶鈾礦
英文
uranniobite-
Age determination data indicate episodic crystallization of uranium minerals.
年齡測定數據表明，鈾礦物有著不同期的結晶。Ore minerals in the colorado-type deposits are of uraninite and coffinite, with associated vanadium and copper minerals.
科羅拉多型礦床中的鈾礦物為晶質鈾礦和水硅鈾礦，與之共生的還有釩，銅礦物。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
對比研究表明，雖然它們各具特色，就脈型富大鈾礦床成礦作用而言，它們又具有較多的共性：重要成礦區的火山噴發皆奠基在古老的結晶基底上；古裂谷（或裂陷）既控制了火山巖帶的發育，又是有利的成礦構造背景；鈾礦賦存對火山巖的巖性沒有明顯的選擇性；鈾成礦的深部控製作用明顯；聯通的構造網路系統是形成富大鈾礦的必要條件。
