在研究鸡街碱性超基性岩杂岩体岩石学和地球化学已有资料基础上，认为本区霞霓钠辉岩平均成分加１０％，Ｆ０＝８６的橄榄石可作为杂岩体的原始岩浆，Ｐ２Ｏ５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，地幔源岩具有明显亏损特征；原始霞霓钠辉岩岩浆经约２９．６％结晶分异形成霓霞岩，霓霞岩岩浆再经约４７．２％结晶分异形成磷霞岩。由此建立起杂岩体的成因模式。
Based on the existing data of the petrological and geochemical characteristics of the Jikou alkaline ultrabasic rock complex, it is considered that the average composition of the Xiaji Naodixene in this area is increased by 10%, and the olivine with F0 = 86 can be used as a complex The original magma, P2O5, estimated that this magma was the product of about 3% partial melting of the mantle rock; mixed modeling calculations of petrology show that the mantle source rocks have obvious depletion characteristics; the original Xia naodi pyroxene magma is crystallized by about 29.6% Differentiation of the formation of Ni Xia, Ni Xia magma and then by about 47.2% of the crystallization of the formation of phosphorous Xia Yan. The formation of complex rock genesis pattern.
