河南嵩县石门铷矿地质特征及成因浅析

摘要

Shimen rubidium deposit of Songxian occurred in Indosinian alkaline syenite of which the main com-positions are K-feldspar.Magmatic activities,for which Indosinian period is an important period in the area, provide a rich source of material for the formation of rubidium ores and rare earth elements.The rubidium part of the rock mass was activated and enriched through the tectonic magmatic hydrothermal fluid,and thus formed the rubidium deposits in the area.The research on the basic characteristics such as rock mass compo-sition and mineral composition of the ore-bodies suggested that in the outskirts of this area and in Fangcheng and Anyang of Henan province similar rock occurred and the prospecting potential there was great.This pa-per proposed that the activity of research on alkaline rock and ore prospecting should be increased.%嵩县石门铷矿赋存于印支期碱性正长岩体中，岩体中主要成分为钾长石，印支期是本区岩浆活动的重要时期，岩浆活动为本区铷矿、稀土元素的形成提供了丰富的物质来源。后经构造岩浆热液活动使岩体中的铷部分活化、富集，而形成本区铷矿床。通过对本区岩体成分、矿体矿物成分等基本特征的研究，认为在本区周边及河南省的方城和安阳等地存在类似的岩体，找矿潜力较大，应加强对碱性岩体的研究及找矿。
