Twelve sub-members can be further divided.
CPEDC3 can be further subdivided into three sub-members: upper, middle, and lower sub-member.
Despite the different site formation processes the lithic industry of both sub-members is similar although quartz utilization is somewhat more prominent in the SASL sub-member.
Data from the earliest phase of the SAS member, comprising the basal SASU and SASL sub-members from caves 1 and 1A are discussed.
Exploration of the Dongying Depression shows that four sets of source rocks exist in the Es 4 x, Es 4 s, Es 3 x, and Es 3 z sub-members and that the total thickness of these source rocks exceeds 2000 m.
Open image in new window Fig. 12 Seismic facies and well-correlation framework showing the sedimentary facies and geometry of IVF in the J2s 1 3 sub-member (A1), J2s 2 1 sub-member (A2), and J2s 2 2 sub-member (A3).
The SASU sub-member contains in situ deposits that include hearths, in contrast to the underlying SASL sub-member that was subject to post depositional disturbance.
The lowermost SASU sub-member formed most likely around 100 000 years ago during a period associated with increased precipitation whereas the age of the underlying SASL sub-member is uncertain.
The older SASL sub-member, not previously described as an independent unit, contains relatively more grazers suggesting drier and more open habitats.
Multi-phase nearshore subaqueous fans developed in the Es 4 x sub-member in the northern zone of the Minfeng Sag.
