Abstract

Analysis of the distribution of rare-earth elements (REE) in veins and rocks of the Dzhimidonskii vein polymetallic deposit (North Ossetia, Russia) formed in the Middle Jurassic Period shows that the sources of REE and ore components were represented by a combination of host rocks of different compositions (PR₃–PZ₁ and PZ₃) and alternated with time. Geochemical data were used as a basis for the development of new methods of equilibrium-dynamic modeling and assessment of the effect of the changes in space and with time of fluid flows from different sources on the processes of ore formation.

热液脉铅锌矿形成过程：地球化学数据和热力学模型

摘要

对中侏罗世形成的Dzhimidonskii脉状多金属矿床（俄罗斯北奥塞梯）的脉岩中稀土元素（REE）的分布分析表明，稀土元素和矿石成分的来源以主体组合为代表。不同成分的岩石（PR ₃ –PZ ₁和 PZ ₃）并随时间交替。地球化学数据被用作开发平衡动力学模型的新方法和评估不同来源的流体流动的空间和时间变化对矿石形成过程的影响的基础。
