摘要

煌斑岩是一类Si O2含量较低、富集铁镁质、碱质以及挥发分的浅成脉岩。总结前人的研究成果发现

形成于不同时代、不同构造背景下的煌斑岩却有着相类似的岩石地球化学特征

即富集LILE和LREE

亏损HFSE和HREE

Sr-Nd同位素以高（87Sr/86Sr）i值及低εNd（t）值为特征。煌斑岩是伸展拉张构造环境的产物

多数学者认为其成因与富集地幔部分熔融有关

可以作为探讨地幔富集作用、同化作用及岩浆混合作用的研究对象。同时

煌斑岩也是金矿床的重要找矿标志之一。

Abstract

Lamprophyre is a class of hypabyssal vein rock

which is low content of Si O2 and is enriched with mafic

alkaline and volatile. From the previous studies

we can get the result that the lamprophyre forming in different times and tectonic setting has the similar litho-geochemical features: enrichment in large ion lithophile elements（LILE） and LREEs

depletion in high field strength elements（HFSE） and HREEs; the Sr-Nd isotope characterized by high（87Sr/86Sr） and low εNd（t）.Lamprophyre is a product of extensional tectonic environment

most scholars believe that the cause is related to partial melting of the enriched lithosphere mantle. It can be used as a research object to study the mantle enrichment

the assimilation and the magmatic mixing. Meanwhile

the lamprophyre is an important indicator of gold deposits.
