为合理地估算出太平洋海山钴结壳资源量,基于我国西太平洋海山钴结壳拖网采样调查资料以及对太平洋海山钴结壳资源分布规律和钴结壳矿区圈定参数指标的深入研究,创造性地按海山不同高度、不同洋壳年龄赋予不同结壳厚度,进而首次计算出太平洋海山干结壳资源量为(507.06～1014.11)×108t,锰为(111.15～222.29)×108t,钴为(3.04～6.08)×108t,镍为(2.23～4.46)×108t,铜为(0.66～1.32)×108t,结壳分布面积为2062862km2.通过Co通量与结壳Co沉积量、结壳厚度的相关分析表明,赋予不同洋壳年龄段的结壳厚度是理论厚度的6.10%～12.20%,这与Kuetal.得出“结壳生长时间只占其整个生命史4%”的认识非常相近,说明所赋结壳厚度基本合理,得出的结壳资源量基本正确.为整个大洋海盆内海山钴结壳资源量的估算提供了新方法.
In order to reasonably estimate the amount of cobalt crusts in the seamounts of the Pacific Ocean, based on the survey data of seamounts in the seamounts of the western seamount in the western Pacific Ocean and the resource distribution rules of cobalt seam in the Pacific Ocean and the delineation parameters of cobalt crust mining areas, For the first time, the amount of dry crusts in the seamounts in the Pacific Ocean was (507.06-1014.11) × 108t, Mn was (111.15 ~ 222.29) × 108t, and cobalt was (3.04 ~ 6.08) at different heights of seamounts and different crust ages. × 108t, nickel is (2.23 ~ 4.46) × 108t, copper is (0.66 ~ 1.32) × 108t, and crustal distribution area is 2062862km2.Correlation analysis of Co flux, The crustal thickness in different age ranges is 6.10% ~ 12.20% of the theoretical thickness, which is similar to Kuetal’s conclusion that “the growth time of crusts only accounts for 4% of the entire life span” The thickness of the crust is basically reasonable and the amount of crustal resources obtained is basically correct, which provides a new method for estimating the amount of seamount cobalt crust in the entire ocean basin.
