Chapter Three Biostratigraphy 3.2.2.4.1- (P1a) Parvularugoglobigerina eugubina - Subbotina triloculinoides interval subzone Definition: Biostratigraphic interval between the LAD of Parvularugoglobigerina eugubina and the FAD of Subbotina triloculinoides. (P1a; defined in Berggren et al., 1995; emendation of Parasubbotina pseudobulloides Subzone (P1a) in Berggren and Miller, 1988) In the present study, the P1a Subzone attains a thickness of 35 meter in Sirwan section, 40 meter in Qulka section and 25 meter in Gali section, (Figs.3. 1, 3. 5 and 3. 7 part 2) (Figs. 3.12-14). The associated planktonic foraminiferal assemblage in Gali section is generally similar to that recorded from the underlying Pá Zone except for the absence of Parvularugoglobigirina eugubina (Luterbacher & Premoli Silva), Parvularugoglobigirina extensa (Blow), Hedbergella monmouthensis (Olsson), and Parasubbotina aff pseudobulloides (Olsson et al), in the lower part. While the Woodringina clytonensis (Loeblich & Tappan), Rectoguembelina cretacea Cushman, and Guembelitria cretacea Cushman were disappeared in the middle interval of this biozone, this Zone characterized by the first appearance of Parasubbotina pseudobulloides (Plummer) and Praemurica pseudoinconstans (Blow) at the beginning of this Biozone in Smaquli area. The associated planktonic foraminiferal assemblage is represented by complete occurrences of the following species in Sirwan area: Parvularugoglobigerina alabaminsis (Liu & Olsson), Rectoguembelina cretacea Cushman, Woodringina clytonensis (Loeblich & Tappan), W. hornerstownensis (Olsson), Chiloguembelina morsei (Kline), Ch. midwayensis (Cushman), Globoconusa daubjergensis (Bronnimann), Parasubbotina pseudobulloides (Plummer), Subbotina trivalis (Subbotina), Globanomalina archeocompressa (blow), G. planocompressa (Shutskaya), Eoglobigerina edita (Subbotina), E. eobulloides Morozova, E. simplicissma Blow, Praemurica taurica (Morozova), P. pseudoinconstans (blow), Guembelitria cretacea Cushman, in Qulka section the assemblages comprise (15) species belonging to (9) Genus like: Woodringina clytonensis (Loeblich & Tappan), W. hornerstownensis (Olsson), Chiloguembelina Morse (Kline), W. midwayensis (Cushman), Globoconusa 78
Chapter Three Biostratigraphy daubjergensis (Bronnimann), Parasubbotina pseudobulloides (Plummer), Subbotina trivalis (Subbotina), Globanomalina archeocompressa (blow), S. planocompressa (Shutskaya), Eoglobigerina edita (Subbotina), E. eobulloides Morozova, E. simplicissma Blow, Praemurica taurica (Morozova), P. pseudoinconstans (blow), Guembelitria cretacea Cushman. In which the Guembelitria cretacea Cushman is represented in the lower part and Woodringina clytonensis (Loeblich & Tappan), and Globoconusa daubjergensis (Bronnimann) is prolonged to the middle part of this biozone. Based on faunal similarities, the combined P1a Subzones of studied sections could be equivalent to the lower part of Morozovella pseudobulloides Zone of Bolli (1966), Caron (1985),P1a Subzone of Blow, (1979); Elnady & Shahin (2001), from Egypt; Arenillas et al.,(2000) Tunisia; present subzones are correlatable with P1a Subzones of Berggren & Miller, (1988); Samir, (2000) In Egypt; to the P1b of Keller, (1988) and Keller et al., (1995), in Tunisia; to the P. pseudobulloides of Obaidalla, (2005), Egypt; and also it is equivalent to the P1a of Berggren and Norris, (1997),Berggren et al.,(1995); Keller, (2002, 2004), Abramovich et al.,(2002); Olsson, (2000); Smit, (2005), SE Spain. The age estimation of this interval depending on Magnetic polarity and recorded datum events by (Olsson et al., 2000), (Keller 2002, 2004) with the time span of (64.90Ma) from the end of Parvularugoglobigerina eugubina to (64.50Ma) first occurrence of, Subbotina triloculinoides, estimating absolute ages based on magnetochron ages. (400 Ky) with (10 Ky/m) high rate of deposition in Qulka section. And with (11.5 Ky/m) high rate of deposition in Sirwan section and (16 Ky/m) high rate of deposition in Gali section. (Fig. 3.13). The estimated age is Early Paleocene (Early Danian). 3.2.2.4.2- (P1b). Subbotina triloculinoides- Globanomalina compressa / Praemurica inconstans Interval Subzone Definition: Biostratigraphic interval between the FAD of Subbotina triloculinoides at the base and FAD of Globanomalina compressa and/or Praemurica inconstans at the top. Remarks: Berggren et al., (1995) introduced this subzone to emend P1b 79
