资源简介:
DEPTH, sediment/rock [m] is given in mbsf. Enrichments are calculated as (metal/Ti)sample/(metal/Ti)crust where Mn/Ticrust = 0.156, U/Ticrust = 0.061 (Rudnick and Gao, 2004)
沉积物/岩石深度(单位:米)以海底以下米(meters below seafloor,mbsf)为计量单位。富集因子按(样品中金属与钛的比值)/(地壳中金属与钛的比值)计算,其中地壳中锰与钛的比值(Mn/Ti_crust)为0.156,铀与钛的比值(U/Ti_crust)为0.061(Rudnick和Gao,2004)
