从40年代末发现稀有元素矿化花岗岩北尼日利亚含铌铁矿花岗岩以来,关于它的成因就一直存在着激烈的争论。开始,认为它们是岩浆成因的,到50年末—60年代初,以A·A·别乌斯为首的一些苏联学者提出了交代成因说,把这类花岗岩称之为“变花岗岩”,到70年代出现了所谓的中间(过渡)观点,在苏联有一些学者(B·N·科瓦连科,M·B·库兹明科等)又重新提出岩浆成因说。

Since the discovery of the North Niger-Niobite granite, a rare-element mineralized granite, in the late 1940s, there has been a heated debate about its causes. At the beginning, they were considered to be of magmatic origin. By the late 1950s-early 1960s, some Soviet scholars led by AB Huis proposed the genesis of such granites as “granite” to 70 The so-called intermediate (transitional) perspective emerged in the years, and some scholars in the Soviet Union (BN N. Kovalenko, M.B. Kuzminko, etc.) resurrected the cause of magma.
