1·Under these conditions, new minerals like biotite, diopside and scapolite grew.
在这些条件下，新的矿物如黑云母、透辉石和菱角石生长起来。
2·Symbiosis with acidic potassium feldspar, plagioclase, biotite.
与钾长石、酸性斜长石、黑云母共生。
3·REE distribution in the first phase intrusive rock descends in an order of pyroxenite to biotite pyroxenite to apatite rock.
第一期侵入岩较其它期次侵入岩ree含量高，按辉石岩—黑云母辉石岩—磷灰石岩的顺序增加。
4·The middle Jurassic Yeba formation volcanics, Paleocene biotite granite porphyry, Miocene quartz monzonite and Oligocene granite porphyry could be found in the ore field.
矿区出露中朱罗统叶巴组火山次火山沉积岩、古新世黑云母花岗斑岩、中新世二长石英斑岩以及渐新世花岗斑岩。
5·Biotite is a subordinate constituent of the mafic and ultramafic rocks generally.
黑云母一般是镁铁质及超镁铁质岩石中的次要成分。
