The spider diagram of trace elementratio and the REE distribution patterns show the characteristics of the island arc calc alkaline series.
微量元素比值蛛网图和稀土元素配分型式具有岛弧钙碱性玄武岩的特征。

The stable elementratio of compatible and incompatible elements implies that they are liquid immiscible congeners coming from a primitive magma consisting of mixed carbonatites and silicates.
稳定元素比值和相容、不相容元素同等富集则表明它们是碳酸岩和硅酸盐混合的原始母岩浆液态不混熔的产物。

In this study, 1003 core samples were collected, found 557 fossils of ostracods, identified the 15 fossil assemblage, the measured carbon and oxygen isotopes 252, and 189 trace elementratio data.
