Chapter Four Depositional Environmenment and Paleoecology 4.4.1- Maastrichtian The Maastrichtian succession represented by upper most part of Shiranish Formation (samples 1-5), Reddish to pale brown succession (Shiranish-Tanjero transition unit), (Samples, 6-40) and Tanjero Formation (samples, 41-113) in Smaquli area, while in the other localities, the studied part of Late Maastrichtian succession, represented by the upper part of the Tanjero Formation (in Dokan, Qala Cholan, Barzinja and Sirwan valley) is characterized by the following parameters: 1- The most diverse assemblage of planktonic foraminiferal species richness ranged from 45 – 55, P/B ratios from 65-80% and Aggl/Calc percent from 15-25% (From CF8 – CF2) Zones, with decreasing the species richness in (CF1) Zone which is being 34-27 and slightly increasing in Agglutinated/Calcareous percent to 35%, In Smaquli section (Fig. 4, 3). 2- Planktonic foraminifera species richness from 35 – 45, P/B ratios from 50-70% and Aggl/Calc percent from 15-20% with decrease in species richness in (CF1) Zone from 24-20 and slight increase of Agglutinated/Calcareous percent to 30%, In Qulka section (Fig. 4 ,4). 3- Planktic foraminiferal species richness is ranged between 35 -45, P/B ratios between 55-70% and Aggl./Calc. percent from 18-30%, with decreasing the species richness from (CF2 &CF1) Zones from 30-22 and slightly increasing in Aggl./Calcar. Percent 50% within the upper most part of (CF1), In Sirwan section (Fig. 4, 5). 4- Planktonic foraminiferal species richness is 25, P/B ratios are 45% and Aggl./Calc. Percent ranged between 35-40% in the lower part of Qishlagh section (sample 1-11) with decreasing in Agglu./Calc. percent 10–20 in the middle part (sample 12-33) and increasing to 35-40% in (samples 35-46) (Fig. 4 ,6). 5- Planktonic foraminifera species richness is 30, P/B ratios are 45% and Aggl/Calc percent is 23% in the lower part of Kato section (samples, 1-19) 93
