1.A mottled green rock composed of diabase.
2.A dark, fine-grained igneous rock; diabase.
3.According to the geological characteristics, the mafic dykes in Huangling area mainly include diabase and diabase-prophyrite, with nearly NEE trend and NNW trend.
黄陵地区的基性岩墙群主要由
辉绿岩脉和辉绿玢岩脉组成 ,走向主要为NEE向 ,少量为NNW向 .
4.This zone consists of basalt, diabase and other basic intrusive rock, and the isotopic age is between 259 Ma and 292 Ma.
它们的同位素年代为（259±09）Ma-（292。0±0．5）Ma。
5.The zircon, from the diabase-gabbros, U-Pb age of 402 Ma shows that the basic swarms were intruded in the middle Palaeozoic.
作者同时获得了402 Ma的单颗粒锆石U-Pb年龄,表明这些基性侵入岩群形成于中古生代。
6.Cataclactic and mylonitic texture as well as massive structure can be found in the rim of diabase dikes and veins which have been strongly altered and mainly consist of albite, amphibole, chlorite, epidote and calcite with a little residual plagioclase and pyroxene.
辉绿岩受断裂控制 ,岩脉边部具碎裂结构、糜棱结构、块状构造。 岩石蚀变强 ,除少量的斜长石、辉石原生矿物残余外 ,主要由钠长石、角闪石、绿泥石、绿帘石和方解石等变质矿物组成。
7.According to the isotopic chronological determination, the Rb Sr isochron age of the diabase whole rock within the fault zone is (100±5.9)Ma, the 40 Ar/ 39 Ar plateau age of the augite is 105Ma.
在依兰－伊通断裂带内利用40Ar／39Ar法测得断层岩（云母石英片岩）中黑云母单矿物的年龄为（100±2．3）Ma。
8.Through opencut mining of Cihai hidden iron ore deposit in recent years, it is found that there are multiperiodic diabase walls penetrated the steeply north-inclining iron ore bodies in different directions in early postmineral period so as to destroy the Integrity of the iron ore bodies and divide them into many small south-inclining bodies.
通过对该隐伏矿床的露天挖掘开采，发现铁矿床在成矿后，早期有多期次
辉绿岩墙以不同方向穿插于向北陡倾之铁矿体中，从而使铁矿体的完整性受到破坏，肢解成众多向南倾小矿体。
9.Based on an analysis of geochemical characteristics of rocks and trace elements as well as rare earth elements, this paper holds that they are products of crystallization differentiation of the same magma, that the major ore resource of this area is copper, and that gabbro-diabase is the main ore-bearing horizon.
通过对岩石化学特徵和微量元素、稀土元素地球化学特徵的剖析，表明其是同一岩浆结晶分异的产物，本区主要矿产应为铜，辉长
辉绿岩是主要的含矿层位。
10.The results showed that the continu- ous basalt fiber can be prepared with the length maximum of 15 m and diameter of 12.2μm by choosing Luoyang diabase in Shannxi Province as the source ore and adopting straticulate alumina and chromium oxide crucible ladder-shape with a orificed tip of 13 mm in height and 4 mm in diameter.
结果表明:选择陕西略阳
辉绿岩矿作为玄武岩连续纤维的原矿,采用分体式氧化铝氧化铬坩埚,高度为13 mm,孔径为4 mm,台阶式漏嘴纺制玄武岩连续纤维,最长能成形15 m,纤维直径为12．2μm。
