| 摘 要： | 辽宁金伯利岩中镁铝榴石的含量与金刚石的含量成正比。富含矿的岩体中镁铝榴石颜色有紫色、红色和橙色等种类,其中以紫色的为主,金刚石的含量越多紫色类型所占比例就越大。 镁铝榴石中Cr_2O_3和CaO的含量随其颜色的加深而升高;Al_2O_3、MgO、TiO_2的含量变化则相反。富矿岩体中富铬(>5％)镁铝榴石的含量高于中等含矿和贫含矿的岩体。 文中还列出了山东和贵州金刚石矿中镁铝榴石的资料以资对比。

| Abstract: | The content of pyrope is directly proportional to that of diamond in kimberlites of Liaoning Province. Pyrope discovered in the kimberlites ranges in colour from purple to red and orange. Purple pyrope is dominant, whose proportion tends to increase with increasing content of diamond. It is found that the darker the colour of pyrope, the higher the contents of Cr_2O_3 and CaO in it. An opposite trend has been recognized for Al_2O_3, MgO and TiO_2. The content of Cr-rich(>5%) pyrope is higher in rich-ore rock bodies than in medium or barren rock bodies. |
