随着沿海地带经济建设的迅速发展,人们越来越多地发现,在沿海地带是纵横交织的埋藏槽谷。这些埋藏槽谷,对沿海地带的工程建设、地面不均匀沉降、地下水资源和部分矿产资源的开发以及航道整治等有重大影响。非洲西海岸的一些金刚石砂矿、阿拉斯加诺姆地区的一些黄金砂矿和我国华南沿海的部分砂矿的成因和分布,都与埋藏槽谷有关。我 With the rapid economic development in the coastal areas, people are increasingly discovering that the coastal areas are intertwined buried troughs. These buried troughs have a significant impact on engineering construction in coastal areas, uneven ground settlement, exploitation of groundwater resources and some mineral resources, and waterway regulation. Some of the diamond sands on the west coast of Africa, some gold sands in the Alaskan Ngam region and some of the placer deposits along the southern China coast are all related to the buried troughs.
