松树沟蛇绿岩中镁铁质岩的Ｓｍ－Ｎｄ全岩等时年龄为１０３０±４６Ｍａ，εＮｄ（ｔ）＝＋５．７，模式年龄在１４２２－１２７１Ｍａ之间，矿物的内部等时年龄为９８３±１４０Ｍａ。全岩等时年龄为其形成上限，矿物内部等时年龄为其变质年龄，说明该蛇绿岩形成于中元古代中、晚期。镁铁质岩的εＮｄ（ｔ）在＋４．２－＋６．９之间，是ＤＭＭ与ＥＭＩ两个地幔端元的混合产物；２０６Ｐｂ／２０４Ｐｂ在１８．０６－１８．６６之间，２０７Ｐｂ／２０４Ｐｂ和２０８Ｐｂ／２０４Ｐｂ值较高，分别在１５．５５－１５．６０和３７．５９－３８．３８之间，２０７Ｐｂ／２０４Ｐｂ和２０８Ｐｂ／２０４Ｐｂ对２０６Ｐｂ／２０４Ｐｂ的关系表明，岩浆源于具ＤＵＰＡＬ异常的源区，（２０７Ｐｂ／２０４Ｐｂ）ｉ相对（２０８Ｐｂ／２０４Ｐｂ）ｉ更偏离ＮＨＲＬ可能是变质流体作用的反映。εＳｒ（ｔ）值较高且变化大，可与蛇绿岩类比，８７Ｓｒ／８６Ｓｒ比值变化大，可能与海水蚀变作用有关。据此推测，松树沟蛇绿岩代表洋壳残片。
The Sm-Nd whole-rock age of mafic rocks in the Songshugou ophiolite is 1030 ± 46Ma, εNd (t) = 5.7, and the model age is between 1422 and 1271Ma. The internal isochron age of the minerals is 983 ± 140Ma. The isochron age of the whole rock is the upper limit of its formation, and the isochron age of the mineral is its metamorphic age, indicating that the ophiolite was formed in the middle and late Proterozoic. The εNd (t) of mafic rocks ranges from + 4.2 to + 6.9 and is a mixture of DMM and EMI mantle end-units; 206Pb / 204Pb is between 18.06-18.66 and 207Pb / 204Pb And 208Pb / 204Pb values were higher at 15.55-15.60 and 37.59-38.38, respectively. The relationship of 207Pb / 204Pb and 208Pb / 204Pb to 206Pb / 204Pb shows that the magma originated from the sediments with DUPAL anomalies Source region, (207Pb / 204Pb) i Relative (208Pb / 204Pb) i Deviation from NHRL may be a reflection of metamorphic fluids. The εSr (t) value is high and varies greatly, and can be compared with ophiolite. The ratio of 87Sr / 86Sr varies greatly, which may be related to seawater alteration. According to this speculation, the Songgou ophiolite on behalf of the ocean shell fragments.
