Results from ICP-MS and EPMA analysis show that serpentinite is dominated by Cr-spinel group minerals with an abundance of Cr up to 6187×10-6 and Cr#(=100Cr/(Cr+Al))ranging between 60 and 69,indicating that the formation environment may have relations with supra-subduction zone ophiolite.

补充资料：流纹岩
| 流纹岩 rhyolite 一种酸性喷出岩。成分与花岗岩相当。灰白色或浅粉红色。常见有流纹构造和斑状玻璃质、球粒、霏细、显微文象等结构。斑晶常为石英、碱性长石，有时有少量斜长石；基质一般为致密的隐晶质或玻璃质。产状多为岩丘。脱玻化明显的流纹岩称为流纹斑岩。流纹岩在中国东南沿海各省有广泛分布，北方辽宁、内蒙古、河北、山西、山东、吉林、黑龙江也都有分布。与之有关的矿产有高岭石、蒙脱石、叶蜡石、明矾石和黄铁矿等。
