Abstract
Abstract. One of the best continuous and fossiliferous Late Santonian-Early Campanian successions in Israel is the approximately 6m thick Kabri section in northern Israel. Its chalky marls were deposited in an outer shelf to upper slope environment with minor depth fluctuations. This Santonian/Campanian interval was studied examining calcareous nannoplankton, palynomorphs, ostracods and benthonic and planktonic foraminifera. The planktonic foraminiferal Dicarinella asymetrica - Globotruncanita elevata concurrent range zone was first observed in Israel in the Kabri section. The first occurrence of Aspidolithus parcus parcus herein is characterized by small specimens, difficult to determine by light microscopy. The lower boundary of the Campanian in this sequence was defined by the first occurrence of G. elevata, in accordance with the ammonite stage definition. This datum line nearly coincides with the first occurrence of the nannofossil marker A. parcus parcus and with the base of the Leguminocythereis dorsocostata (S-4) ostracod zone, both slightly above the foraminiferal boundary.
Highlights
Coniacian-Maastrichtian sediments in northern Israel consist genemlly of rather homogenous chalky units (Mount Scopus Group; Flexer, 1968)
The CC 17 Zone is defined as the interval between the regular FO of C. ohscurus to the FO of Aspidolithus parcus and as Late Santonian-earliest Campanian in age (Sissingh, 1977; Perch-Nielsen, 1985)
The most indicative Campanian nannofossil species Aspidolithus parcus parcus was found from sample AF 757 upwards
Summary
Coniacian-Maastrichtian sediments in northern Israel consist genemlly of rather homogenous chalky units (Mount Scopus Group; Flexer, 1968). The fossils in the Kabri section are rather well preserved, but in some samples recrystallization or etching is observed The section can he divided into three nannofossil biozones (see Sissingh, 1977; Perch-Nielsen, 1979, 1985): Samples AF 75 1-754: Lucianorhabdus cayeuxii (CC 16) Zone - Late Santonian. The CC 17 Zone is defined as the interval between the regular FO of C. ohscurus to the FO of Aspidolithus parcus and as Late Santonian-earliest Campanian in age (Sissingh, 1977; Perch-Nielsen, 1985). The most indicative Campanian nannofossil species Aspidolithus parcus parcus was found from sample AF 757 upwards The specimens of this form in the lowest samples of the CC 18 Zone (AF 757-758) are about 5-6 microns in size (PI.I , figs 4-5) and difficult to determine by light microscopy.
