1 Introduction. The stable calcium (Ca) isotopic composition of marine carbonate archives (δ 44/40 Ca) was proposed to be an important palaeo-environmental and palaeo-oceanographic proxy, mainly because of the linkage between the Ca and C geochemical cycles. The continental weathering of Ca bearing carbonates and silicates is the main source of Ca to the ocean, while authigenic, biogenic and ...Zoophycos is found off NW Africa in water depths > 2,000 m, in sediments with C org contents of 0.3-1.8%. It is possible to recognize in the core sections all of the morphological spreiten types of Zoophycos which were described from ancient sediments.
