摘要
通过对海南岛土外山金矿区抱板群斜长角闪片岩地球化学和Sm-Nd同位素的系统研究,认为这套斜长角闪片岩的原岩为起源于亏损地幔区的早元古代拉斑玄武岩。
n the light of the systematic studies of the geochemistry and Sm-Nd isotope of plagioclase-hornblend schist of the BaobanGroup in Tuwaishan of Hainan Island,we think that the protolith of the plagioclase-hornblend schist was a suit of Lower-Pro-terozoic tholeiite that was derived from the depleted mantle.
