郯庐断裂的神奇功能,不仅表现在它是一条活动的断裂带,它还是一条重要的成矿带和闻名于世的地震活动带。这三者与板块运动、岩浆活动和地壳形变的关系十分密切。郯庐断裂带的有些情况,已逐渐被人们所了解认识。但有些情况仍然鲜为人知,且有待继续探讨。一、郯庐断裂带,泛指北起黑龙江、南止长江边、绵延2400多公里、总体上呈北东走向、纵贯中国大陆东部的巨型深断裂。半个多世纪以来,一直为地质、探矿、地球物理和地震地质工作者所倍加关注。然而,在上世纪60年代以前,许多研究者带着不同任务和目的,局限于对断裂带的某些地段进行考察和勘探。结果在不同地段断裂带命名了一些地方性的
The magical function of the Tan-Lu fault is not only reflected in the fact that it is an active fault zone, but also an important metallogenic belt and the world-famous seismic belt. These three are closely related to plate movement, magmatism and crustal deformation. Some cases of the Tan-Lu fault zone have gradually become known to people. However, some situations are still poorly understood and are yet to be explored. First, the Tan-Lu fault zone refers to the north of Heilongjiang, south of the Yangtze River, stretches more than 2,400 kilometers, the overall north-east trend, runs through the eastern China’s giant deep fault. For more than half a century, geological, prospecting, geophysical and seismic geologists have been twice as attentive. However, by the 1960s, many researchers were confined to different missions and purposes to investigate and explore certain sections of the fault zone. As a result, the fault zones have been named for some places in different locations
