(Table 3) Organic-petrographical composition of ODP Leg 164 sites

Sediment depth is given in mbsf. Value of <1 = present. The composition of the structured organic matter was determined by a semiquantitative estimation method that is based...沉积物深度以海底以下米数（meters below seafloor，mbsf）为单位。数值小于1即代表该组分存在。结构化有机质的组成通过一种基于……的半定量估算方法进行测定。
