花崗岩侵入體的同化混染作用,早就引起蘇聯學者們的注意。許多岩石學家們對這些問題有廣泛的興趣。B.H.羅道奇尼科夫認为卡爾貝的閃長岩是混染岩。烏拉爾的混染岩曾经A.H.查瓦理茨基,索科洛夫等描述過。阿法鈉謝也夫等在北高加索的工作認为以侵入相为主的,由成份為花崗閃長岩及花崗質岩至輝長閃長岩質及輝長岩質的岩石組合;後者系因局部的同化及花崗質岩漿被同化的基性物質污染而成。巴達勒卡等在1940年及郭特曼在1943年都曾記叙過花崗岩的混染作用,其結果產生了較為基性的岩石——花崗閃長岩,閃長岩甚至於成份與輝長岩及成份為輝長——紫蘇輝長岩的岩類。H.H.克魯泡特金於1952年在中部哈薩克斯坦看到花崗岩常因基性火山岩的同化而具有閃長岩與花崗閃長岩的成 The assimilation and contamination of granite intrusions have long drawn the attention of Soviet scholars. Many petrochemists have a broad interest in these issues. B.H. Rhodochinnikov considers Kalbby’s diorite to be a mixed rock. The contaminated rocks in the Ural used to be described by A.H. Chavacezki, Sokolov et al. The work of Alfa-Shevchenko et al. In the North Caucasus suggests that the intrusive facies consists of a combination of granodiorite and granitic rocks to gabbro and gabbro rock assemblages; the latter due to Local assimilation and granitic magma are contaminated with assimilated basic substances. Badaluca et al. (1940) and Gottman (1966) described the contamination of granite. As a result, the more basic rocks - granodiorite, diorite and even gabbro And the composition of glorious - perilla syenite rocks. H.H. Kropotkin saw in central Central Kazakhstan in 1952 that granite often contains diorites and granodiorites due to the assimilation of basic volcanic rocks
