多数同行都认为层控矿床中的微莓球状硫化物是早期成岩阶段的产物。西成铅锌矿田中微莓球体的发现和研究说明它们既有早期成岩阶段形成的,又有后生阶段形成的,在形成后还可与矿床一起遭受进一步的改造和变化。因此,研究各种不同类型的微莓球体,不但可以说明它们的成因,而且还可以为矿床的分类和成因提供依据。 Most colleagues agree that micro-raspberry globular sulphides in stratiformized deposits are the product of early diagenetic stages. The discovery and study of the medium-sized microspheres in the Xicheng lead-zinc ore deposit indicate that they were both formed in the early diagenesis stage and formed in the epigenetic stage and could be further modified and changed together with the deposit after the formation. Therefore, the study of different types of micro-sphere, not only can explain their causes, but also can provide a basis for the classification and genesis of the deposit.
