河南泌阳—确山萤石矿带地质特征及找矿方向

Geological Characteristics and Prospecting Direction of the Biyang County-Queshan Fluorite Ore Belt in Henan Province

泌阳—确山萤石矿带是河南重要的萤石矿成矿带之一,已发现萤石矿床(点)50余处,矿床成因类型主要为岩浆期后的中—低温热液充填型。萤石成矿严格受断层控制,后期的构造活动和岩浆侵入对萤石矿体的连续性和矿石品位有较大的影响。本文通过分析典型矿床,总结萤石矿地质特征和成矿规律,对区内找矿前景进行了初步评价。认为该区成矿地质优越,以往萤石矿勘查程度不高,仍有较大的找矿空间,预测区内具有大型萤石矿的找矿前景。

The Biyang-Queshan fluorite ore belt is one of the important fluorite metallogenic belts in Henan province. More than 50 fluorite deposits have been found in the belt. The fluorite mineralization is strictly controlled by faults. The late tectonic activity and magmatic intrusion have great influence on the continuity of fluorite orebody and ore grade. In this paper, the geological characteristics and metallogenic regularity of fluorite deposit are summarized by dissecting typical deposits, and the prospecting prospect in this area is preliminarily evaluated. It is considered that the ore-forming geology of this area is superior, the exploration degree of fluorite is not high, there is still a large prospecting space, and the prospecting prospect of large-scale fluorite deposits in this area is predicted.
