摘要:
河南伊源玉矿床位于河南省栾川县陶湾三合村,矿体分布严格受地层层位和岩性控制,矿体出露于上元古界煤窑沟组上段白云质大理岩与辉长岩接触带中,矿体产状与原岩的层理产状基本一致。矿床规模较大,矿石矿物成分主要为透闪石,含量大于95%,莫氏硬度为5.7~6.4,玉质细腻,色泽丰富多彩,且以白玉为主,与我国最著名的新疆和田玉矿物成分相似。伊源玉易于雕刻,其雕品晶莹闪烁,形态优美,琢雕效果好,在国内外市场上竞争力较强,具有良好开发利用前景。

Abstrast:Yiyuan jade deposit locates in Taowan Sanhe village, Luanchuan county, Henan province. The ore distribution is strictly controlled by stratigraphic and lithologic characteris-tics. The orebody outcrops coal mines in upper Proterozoic upper segment Xiagou dolomitic marble in contact with gabbro zone. The orebody occurrence is basically consistent with the original rock. As a large deposit, the orebody composed mainly of tremolite more than 95%, Mohs hardness of it is 5. 7~6. 4, and jade is fine and smooth, bright and colorful, and mainly white,which is similar with ingredients like Xinjiang Hetian jade, our country's most famous jade.
