利用缓发中子法测定了世界各处各种类型的许多海洋沉积样品中铀的浓度,得出如下几个关系:1.沉积于罗德岛 Pettaquamscutt 河缺氧环境的沉积物中,有机碳的分含量与铀的浓度成正比关系。其浓度范围从7%的有机碳和7 ppm 的铀到14%的有机碳和和30ppm 的铀。在墨西哥湾Sigspee 海丘沉积物的钻样中也发现类似的比例关系。2.锰结核中的铀和钙的浓度之间也有直接
Determination of uranium concentrations in many marine sediment samples of various types around the world using the slow neutron method yields the following relationships: 1. In sediments deposited in anoxic environments at the Pettaquamscutt River in Rhode Island, organic carbon The sub-content is proportional to the concentration of uranium. Concentrations range from 7% organic carbon and 7 ppm uranium to 14% organic carbon and 30 ppm uranium. Similar proportions were also found in the drillings of Sigspee deposits in the Gulf of Mexico. 2. Manganese nodules in the uranium and calcium concentrations also have direct
