(Table T1) Distribution of Miocene to Pliocene calcareous nannofossils, Hole 177-1088B@en

Six calcareous nannofossil abundance levels were recorded, as follows:VA = very abundant (>50 specimens per field of view).A = abundant (11-50 specimens per field of view).C = common (1-10 specimens per field of view).F = few (0.1 to <1 specimens per field of view).R = rare (0.02 to <0.1 specimens per field of view).RR = very rare (<0.02 specimens per field of view).Preservation of nannofossils was recorded as good (G), moderate (M), poor (P), and very poor (VP). Some samples were barren (B) of calcareous nannofossils. Reworking phenomena were noted in some Eocene intervals.本次记录了6级钙质超微化石（calcareous nannofossil）丰度等级，具体如下：VA为极丰富（每视野>50个标本）；A为丰富（每视野11~50个标本）；C为常见（每视野1~10个标本）；F为少量（每视野0.1至<1个标本）；R为稀少（每视野0.02至<0.1个标本）；RR为极稀少（每视野<0.02个标本）。钙质超微化石的保存状况被划分为良好（G）、中等（M）、较差（P）与极差（VP）四个等级。部分样品不含钙质超微化石。部分始新世（Eocene）地层层段中观测到再沉积现象。
