(Figure 4) Radiolarian range chart of ODP Hole 138-847B, part II@en

DEPTH, sediment is given in mbsf. Relative abundance of individual species: R = rare (<10 specimens); F = few, (10-100 specimens); C = common (100-200 specimens), and A = abundant (>200 specimens). A- signifies that a species was looked for and not found, small case letters = specimens found that are thought to be reworked, ? = a dubious identification.沉积物深度以海底以下米数（mbsf）为单位。单个物种的相对丰度分级如下：R代表稀少（标本数量<10件）；F代表少量（10~100件标本）；C代表常见（100~200件标本）；A代表丰富（标本数量>200件）。A-表示该物种经搜寻但未被发现；小写字母表示经认定为再沉积的标本；？表示鉴定结果存疑。
