河南鲁山—舞阳石墨矿带地质特征与勘查开发

鲁山—舞阳石墨矿带为河南省重要的成矿带之一,石墨矿床为沉积变质型。石墨成矿主要受原岩性质、变质作用控制。后期的构造活动和岩浆侵入对石墨矿床的矿石品位和矿体的连续性也有较大的影响,一方面破坏了矿体连续性,另一方面又促进石墨矿物再次重结晶,使其片度增大,提高了石墨矿的利用性能。应本着保护环境、综合利用矿产资源的原则,在尊重地质规律的前提下,集中连片、统一规划石墨矿的勘查开发布局。

Geological characteristics and exploration-development of graphite mineral belt in Lushan-Wuyang, Henan

The Lushan-Wuyang graphite ore belt is one of the important mineralization belts in Henan Province, and the graphite deposit type is a sedimentary Metamorphic crystalline graphite deposit. Graphite forming ore is mainly controlled by metamorphism and the properties of the original rock. The late tectonic activities and Magma intrusion also have a great influence on the ore grade and the continuity of the ore body of the graphite deposit. On the one hand, it destroys the continuity of the ore body, and on the other hand promotes the re-crystallization of graphite minerals, increasing their scale. Improved the utilization performance of graphite ore. The exploration and development layout of graphite ore should be centralized and unified under the principle of being conducive to environmental protection and comprehensive utilization of mineral resources and respecting geological regularity.
