We present the whole-rock and the mineral chemical data for upper mantle peridotites from the San-Jiang region in Yunnan Province,SW China.These peridotites are part of a Paleo-Tethyan ophiolite belt occurring along the Jinshajiang and Lancangjiang suture zones.All samples of Jinshajiang and Lancangjiang ultramafic rocks are completely serpentinized.The Jinshajiang serpentinites are characterized by no relict of Olivine and Pyroxene,and the Cr number of spinels is 0.32-0.49.
