| 中文摘要: |
| 石宝村矿床位于湖南省资兴市,是一处新发现的石英质玉石矿床。为了查清石宝村石英质玉石矿的资源特征,有效进行玉石品质评价,本研究通过地质普查,基本查明了矿体的地质特征、矿石特征及加工技术性能等,并总结了矿床的成因及找矿标志。矿床内玉石类型丰富,分为腊黄色石英岩玉、胭脂白色石英岩玉、青白色石英岩玉和朱红色石英岩玉4种。地球化学分析表明矿体从上向下有益组分SiO2含量逐渐降低(94.46%→88.90%),体现出玉石品质逐渐变差的特征。本研究可为玉石矿床地质勘查提供借鉴意义。 |
| 英文摘要: |
| Shibaocun quartzite jade deposit is a newly discovered deposit mostly enrichment quartzite jade in Zixing,Hunan Province.In order to find out the resource characteristics of Shibaocun quartz jade deposit,evaluate the quality of jade effectively,this study is based on geological survey,the geological characteristics, ore characteristics and processing technical performance of the ore body are basically ascertained,the genesis and prospecting criteria of the deposit are summarized.Ores in this deposit can divided into four categories on the basis of color, namely waxy quartzite jade, rouge white quartzite jade, greenish white quartzite jade and vermilion one.Geochemical data shows that beneficial component (SiO2) decreases gradually in ore body from the top to the bottom decreases gradually (94.46%→88.90%), which demonstrate the deterioration in the quality of jade.A set of evaluation methods of jade quality is summarized, which can provide reference for geological exploration of jade ore. |
