摘　　要：超大型矿床的形成条件有其特殊性。大厂超大型锡矿产出于南丹—昆仑关基底性深大断裂带上,经过多旋回构造-岩浆活动使矿质继承叠加,最后聚积于燕山晚期的岩浆热液中。大厂超大型锡矿床是各种成矿因素良好匹配,并经长时期的多重富集综合作用的结果。Superlarge ore deposits are special in their ore-forming conditions. Dachang superlarge Sn deposit is formed in the deep-seated basement fault zone. Multi-cycle tectonism-magmatism superimposition leads to the final ore materials concentration in Late Yanshanian magmatic hydrothermal fluid and the deposit is resulted from optimum combination of metallogenic factors and the long-term ore material enrichment.
