有效的矿床勘探通常在基本有前景的地质环境中寻找可能导致强化成矿过程的独特条件。形成矿床的大规模金属聚集通常与特定的构造事件有关。许多研究发现，重要的成矿作用与板块俯冲和吸积/碰撞构造机制有遗传关系。在这里，我们描述了在俯冲和挤压应力作用下，一个活跃的大陆边缘伸展环境也可以定义一个世界级区域成矿省发展的重要构造环境。从145 ~ 70 Ma，沿东亚大陆边缘（EACM），从越南北部，经过中国东部、朝鲜、日本和俄罗斯远东的锡霍特-阿林地区，形成了广泛而多样的矿床群，是一个与区域伸展有关的成矿省的很好的例子。矿床类型多样，流体和金属来源各异，赋存于一系列北东向或北北东向的拉分盆地和变质核杂岩中，并沿相关的张拉断裂发育，反映出受拉张作用的控制。提出了一种新的东亚白垩纪成矿事件的构造成矿模式，以突出在全球此类构造背景下的勘探潜力。
Effective exploration for ore deposits usually seeks distinct conditions within fundamentally prospective geological settings that might lead to enhanced ore-forming processes. Large-scale metal accumulation to form ore deposits is usually associated with specific tectonic events. Many studies have found that significant mineralization is genetically related to plate subduction and accretion/collision tectonic regimes. Here we describe how an active continental margin extensional setting can also define an important tectonic environment for the development of a world-class regional metallogenic province subsequent to subduction and compressional stresses. The extensive and diverse group of mineral deposits formed from 145 to 70 Ma along the eastern Asian continental margin (EACM), from northern Vietnam, through eastern China, Korea, Japan, and to the Sikhote-Alin region of Far East Russia, represents a good example of a regional extension-related metallogenic province. The varied mineral deposits with distinct fluid and metal sources occur in a series of NE- or NNE-trending pull-apart basins and metamorphic core complexes, as well as along associated transtensional faults, reflecting the controls of an extensional regime. A new tectono-metallogenic model for the Cretaceous ore-forming events of eastern Asia is proposed to highlight the exploration potential in such tectonic settings throughout the world.
