近些年来,煌斑岩研究倍受地质学家重视,在诸如煌斑岩分类、成因及其与金矿关系等问题的研究上取得了很大的进展。从目前的资料来看,煌斑岩仍难以根据现有的准则分类,钾镁煌斑岩和金伯利岩最好能从煌斑岩中独立出来,Mitchell建议的“煌斑岩相”的概念比“煌斑岩族”更能体现煌斑岩的特征;而煌斑岩原始岩浆可能并不存在,煌斑岩是普遍类型的基性岩浆在源区或侵位过程中遭受地壳混染的衍生物;Rock等人提出的煌斑岩中温热液金矿成因模式存在明显的问题,因为煌斑岩高含量金多为次生富集的,煌斑岩与金矿伴生的主要原因是二者具相同的构造环境。
In recent years, the study of lamprophyre has been highly valued by geologists, and great progress has been made in the research on the classification of lamprophyre, its genesis and its relationship with gold deposit. From the current information, lamprophyre is still difficult to classify according to the existing guidelines, and the lamproas and kimberlites are best separated from the lamprophyres. The concept of “lamprophyre facies” suggested by Mitchell The lamprophyre can better reflect the characteristics of lamprophyre, while the lamprophyre magma may not exist. The lamprophyre is a common type of mafic magma derived from crustal contamination in source area or emplacement There are obvious problems with the genesis pattern of the epithermal gold deposits in the lamprophyre proposed by Rock et al. Since the gold content of the lamprophyres is mostly secondary enrichment, The same construction environment.
