摘要
贝勒库都克钾长花岗岩是一个富含Sn、As和F的岩体,具同熔型特征,是形成贝勒库都克锡矿的母岩.在岩体形成的后期,经历了钾化—钠化—云英岩化三个交代蚀变阶段.Sn、As等成矿、伴生元素的析出和富集发生在钠化和云英岩化两个阶段,形成了一定规模的锡矿床.
The kaligranite in Belikuduk is rich in Sn, As and F, characterized by syntec-tics.It is the source of Belikuduk algam ore deposits. During the late stage,of formation the rock body underwent kaliumization-sodiumization- greisenization, the three replacement-alteration stages.
The extraction and enrichment of the associated elements Sn and As occurred in the sodiumization and greisenization stages.Hence, a certain scale of algam ore is formed.
