摘要
煌斑岩在自然界分布广泛,是一类暗色矿物含量较高并具有典型的斑状结构的脉岩,出露于从前寒武纪到第四纪的各个时代及各种不同的大地构造单元。作为火成岩的一大类岩石,其一直是地学界尤其是岩石学和矿床学的研究重点。前人对煌斑岩的研究过程中,提出了多种不同的分类标准和成因模式,尚未达到统一。目前对煌斑岩的研究主要聚焦于煌斑岩的成因、成矿效应和地质构造背景示踪方面。本文旨在系统地总结和讨论前人研究的成果,希望为接下来的科研工作提供可靠、全面的信息支撑。
The Lamprophyre is widely distributed in nature, and it is a kind of vein rock with high dark mineral content and typical patchy structure, which is exposed to all ages and various tectonic units from Precambriau to Quaternary.As a large group of igneous rocks,it has been the focus of the study of geology,especially petrology and mineralogy.In the process of research on the lamprophyre,many different classification criteria and genetic models have been put forward,which have not yet reached the same level.At present, the study of the lamprephyre focuses on the genesis,classification,mineralization and geological tectonic background tracing of the lamprophyre.This paper aims to systematically summarize and discuss the results of previous studies, hoping to provide reliable and comprehensive information support for the next research work.
