dolerite

dolerite

1. 1. At Scinto 6 uranium occurs in much altered dolerite below the unconformity.

“辛托6”的铀矿体产于不整合面之下变质甚深的粒玄岩中。

2. The metaperidotite is strongly depleted in TiO_2. The dolerite has low TiO_2 and some of the granitoids on the FAM diagram show a Skaergaard liquid trend.

其变质橄榄 岩、方辉橄榄岩强烈亏损TiO_2，辉绿岩TiO_2也较低，而稀土元素分布模式为平缓型。

3. Petrographical,petrochemical and geochemical data show that the lavas of Byers Peninsula and Cape Shirreff and the dolerite at Siddons Point belong to calc alkaline series and with the characters of lower potassium and magnesium.

岩石化学和地球化学资料表明，百耳斯半岛熔岩、史莱夫角的橄榄玄武岩和西多斯角的粗玄岩等白垩纪火山岩基本属于钙碱性岩系并且具有低钾低镁的特点。

4. 8. The micro-gabbro phase is indentical with the typical Bulawayan dolerite sills.

微辉长岩相与标准的布拉瓦约粒玄岩床相同。

5. quartz dolerite

石英粒玄岩

6. alkali dolerite

碱性粒玄岩

7. Experimental studies on the choices of desiccation parameter for dolerite sample

罗甸辉绿岩石样品干燥参数选择的研究

8. Research on Application of Dolerite in Expressway Asphalt Pavement Surface Construction

辉绿岩在高速公路沥青路面表面层的应用研究

9. Young basic intrusives, which took place late Mesozoic times, formed numerous minor dolerite dykes.

这些早期的侵入性活动，发生在中生代早期，并形成了一些粗玄岩的沟壑。

10. The minerals are disseminated in the schist and hornfelsed schist near the dolerite contact

这些矿物也浸染在靠近粗玄岩接触带的片岩和角岩片岩中。
