| 摘 要： | 在山东新泰市新太古代泰山岩群变质岩系中,首次发现宝石级红刚玉,又称红宝石,商业名称暂定为＂泰山红宝石＂。红宝石产于鲁西地区新太古代二长花岗岩的壳源岩石包体之中,包体岩性以黑云更长变粒岩、黑云片岩、角闪石岩、斜长角闪岩、浅绿色含铬二云片岩为主,是新太古代古老地壳的深融残留;红刚玉与浅绿色含铬二云片岩关系密切,推测是新太古代变质岩中原岩残留斑晶矿物。

| Abstract: | A large number of gem-quality red corundum（also known as ruby） has been found in metamorphic rocks in Archean Taishan group in Xintai city of Shandong province.Its commercial and individual provisional name is ＂Taishan ruby＂.Ruby occurred in rock inclusions in the crust of Neoarchean monzogranite.The property of inclusions is mainly composed of biotite oligoclase granulite,biotite schist,hornblende rock,plagioclase amphibolite and green chromium bearing monzonite mica schist rock.It is the deep melting residue of ancient Archean crust.It has close relation with light green chromium-containing two feldspar micacite.It is regarded that red corundum may be the phenocryst mineral of new Archean metavolcanic rocks. |
