中国琥珀的剖析

ANALYSIS OF CHINESE AMBER

采用红外光谱法、电子顺磁共振谱法和核磁共振谱法,对我国辽宁抚顺矿区和河南西峡矿区的三种琥珀进行了剖析。测得辽宁抚顺矿区的琥珀年龄约为5×10~7a,河南西峡矿区的琥珀年龄约为7×10~7a。上述样品均保存完好,未遭到侵蚀。

Three kinds of amber from two mining sites in China have been measured by the techniques of IR, ESR and NMR. Amber from Fushum mines in Liaoning province has been estimated to be 50 million years old, and Xixia amber from He- nan province is about 70 million years. It is evident that all specimens are well preserved without any weathering.
