在已有云南禄丰鸡街碱性超基性岩杂岩体岩石学和地球化学资料基础上，通过对比，认为本区霞霓钠辉岩平均成分加入１０％ｗ（Ｆ０）＝８６％的橄榄石可作为杂岩体的原始岩浆，按Ｐ２Ｏ５的含量估算出这种岩浆为地幔岩经约３％部分熔融的产物；岩石学混合模拟计算表明本区地幔源岩具有明显亏损特征。亏损地幔可能与先期幔源岩浆活动有关，更可能是岩体含矿性差的直接因素
On the basis of the petrologic and geochemical data of the alkaline ultrabasic rocks in Lufeng chicken street in Yunnan Province, the average composition of Xiaji sodium-dike in this area is considered to be 10% w (F0) = 86% The olivine can be used as the original magma of the complex. According to the content of P2O5, this magma is estimated to be the product of partial melting of mantle rock by about 3%. The petrological simulation shows that the mantle source rocks have obvious loss characteristics. The depleted mantle may be related to mantle-derived magmatism and is more likely to be the direct factor of poor ore-bearing quality
