岩浆岩冷缩裂隙形成机制、类型及成矿作用

岩浆冷缩裂隙是岩浆岩原生裂隙的重要类型。以往多学科、多角度的节理及裂隙研究不同程度地涉及到该类节理，取得了丰富的认识，但这些研究在冷缩裂隙的特点、形成机理、分类、裂隙的基本特征及其影响因素、成矿作用特点等方面系统性尚显不足，认识尚有争议。在前人研究的基础上，通过对不同机制和制约因素下岩浆冷缩裂隙的形成规律、裂隙类型，以及发育特点、裂隙（系统）规模和成矿作用特点等的探讨，分析不同裂隙类型的成矿作用特征，构建受体冷缩裂隙控制的斑岩型矿床的容矿裂隙概念模型，讨论其网状裂隙系统的裂隙特征、网状裂隙系统与斑岩的空间关系及其成矿作用和特点，较系统地归纳了岩浆冷缩裂隙的特点，丰富了斑岩型矿床的研究方法，对该类型矿床的理论研究具有一定的参考意义。

Genetic mechanism, types and metallogenisis of cooling fissures in magmatic rocks

Magmatic cooling fissures are an important type of primary fissures in magmatic rocks. In the past, multi-disciplinary and multi-angle joints and fissure studies have included such joints to varying degrees, and have gained in-depth knowledge. However, these studies are still insufficient in the cooling fissure characteristics, formation mechanism, classification, basic fissures characteristics and their influencing factors, and mineralization characteristics, and the understanding is still controversial. In this work, on the basis of previous studies, we discussed the formation mechanism of magmatic cooling fissures, types, development characteristics, the scale of the fissure (system) and the characteristics of mineralization through different mechanisms and constraints. Then we analyzed the mineralization characteristics of different fissure types and constructed a conceptual model of ore-hosted fissure in porphyry deposits controlled by cold shrinkage of receptors. Finally, we discussed the fracture characteristics of fissure network system, and its spatial relationships and mineralization characteristics with porphyry. These studies systematically summarize the characteristics of magmatic cooling fissure, which will enrich the research methods of porphyry deposits and have certain significant reference to the theoretical research of porphyry deposits.
