The contents of Ni, Au, Mo, W of the deep-seated xenoliths and their host basalts from eastern China are inhomogeneous. The contents of Ni, Au are highest in the mantle-derived xenoliths the contents of Mo, W are highest in the basalts and the mafic granulite, and the leptite and the granitoids, respectively.

地球深部包体中镍、金、钼、钨等成矿元素的含量是不均一的，镍和金在地幔岩包体中含量最高，铝在玄武岩及镁铁质麻粒岩包体中最高，而钨在长英质麻粒岩和花岗岩类包体中含量最高。

Combined with available data, it is comidered that the sourcerock of biotite--leptynite might be intermediate-acid volcanic material of ca.2.7 Ga, and that of migmatized leptite and quartzite might come from granitic crust older than 3.0 Ga. The iron formation was formed on the continental crust base at about 2.7 Ga, and was immediately metamorphosed for the first time.

结合已有的研究资料可以认为，黑云变粒岩的原岩来自2.7 Ga左右的中酸性火山物质，浅粒岩和石英岩的原岩来自3.0 Ga以上的花岗质地壳物质；含铁建造形成于陆壳基底之上，形成时间约2.7 Ga，并于2.5—2.7 Ga之间发生首次变质作用。

We think main metamorphic rock types of this area include mited granite ,mixed metamorphic rock,leptite,etc.

认为变质岩中混合花岗岩、混合岩化变质岩、变粒岩、浅粒岩、黑云斜长片麻岩等为本区的主要变质岩类型；沉积岩以云岩、硅质岩和石英砂岩为主；火成岩脉主要为辉绿岩、煌斑岩和闪长玢岩。

The zircon was dated by using the technique of single-zircon stepwise evaporation-deposition with a thermal ion mass spectrometry (Bernd Kober, 1986 and 1987). The zircon ages are 2.60-2.54 Ga for biotite-leptynite, 3.36-2.62 for mimatized leptite, and 3.53-3.08 Ga for quartzite from the iron formation.

用热离子质谱计双带源蒸发—沉积测定单个锆石晶体年龄的方法对弓长岭含铁建造中黑云变粒岩、混合岩化浅粒岩和石英岩中的锆石作了测定，获得了2.60—2.54 Ga，3.36—2.62 Ga和3.53—3.08 Ga等年龄数据。

The metamorphic rocks of the area consist of granulite, plagioclase-gneis, biotite leptite and various kinds of schists of granulite to amphibolite facies By reconstruction, this metamorphic series is composed of three original formations which inciude five originai rock types: intermediate-acid volcanics formation at the bottom basic-felsic bimodae volcanits formation in the middle and basic-andesitic-felsic volcanics formation at the top...

区内太古代变质岩系广泛发育，其下部为深变质的麻粒岩相地层，上部为中深变质的角闪岩相地层，后者产出红透山式铜锌矿床多处，以及张胡子沟铜矿床和大荒沟硫铁矿床等一系列块状硫化物矿床(图1)。矿石中铅同位素年令为25～26亿年，在形成时代上可以和鞍本地区鞍山群对比。
