Distribution of calcareous nannofossils from IODP Hole 313-M0029A

Sediment depth is given in mbsf.
Abundance: V = very abundant, A = abundant, C = common, Fr = frequent, F = few, R = rare; B = barren; ? = questionable; * = reworked. Preservation: G = good, M = moderate, P = poor. LO = last occurrence, FO = first occurrence, LcO = last common occurrence.

沉积物深度以米/百英尺表示。丰度：V=非常丰富，A=丰富，C=常见，Fr=频繁，F=少数，R=稀有；B=贫瘠；?=可疑；*=重加工。保存状态：G=良好，M=适中，P=较差。LO=最后一次出现，FO=第一次出现，LcO=最后一次共同出现。
