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.

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.

Then pMD-P80 is digested by the enzymes Xho I and Apa I, separated and linked to the linear plasmid pEGPF-C1 after digested by Xho I and Apa I. So the recombined expression plasmid pGFP-P80 is achieved. Then it is sequenced, PCR and digested by the restriction enzymes Xho I and Apa I. The results give that pGFP-P80 is achieved successfully and the insert sites, direction and reading frame are all right. It builds the basis for expressing, purifying, gaining p80 protein from mammiferous cells.
