东秦岭松树沟蛇绿岩主要由变质橄榄岩和变质玄武岩组成。变玄武岩全岩ＳｍＮｄ同位素等时年龄为（１０３０±４６（２δ））Ｍａ，ＩＮｄ＝０．５１１６１±５（２δ），εＮｄ（ｔ）＝＋５．７±０．２，代表蛇绿岩中玄武岩的形成年龄。这一年龄的确定，为探讨秦岭区中晚元古代的古构造格局提供了重要的证据
The East Qinling Songshugou ophiolite is mainly composed of metamorphic peridotites and metamorphic basalts. The isochron age of the whole basalt rock is 1030 ± 46 (2δ) Ma, INd = 0.51161 ± 5 (2δ), εNd (t) = + 5.7 ± 0.2, representing the ophiolite The formation of basalt ages. The determination of this age provides important evidence for exploring the Paleo-Proterozoic paleotectonics in the Qinling area
