“…C 4 plants have a δ 13 C of −10 to −16 (Collister et al, 1994). Lipids are depleted in 13 C relative to bulk plant tissue by 4 − 8 (Rieley et al, 1991(Rieley et al, , 1993Collister et al, 1994;Chikaraishi et al, 2004). The compounds utilized for this study, n-alkanoic acids, exhibit isotopic compositions of −38 for C 3 plants and −20 for C 4 plants (Chikaraishi et al, 2004).…”

The compounds utilized for this study, n-alkanoic acids, exhibit isotopic compositions of −38 for C 3 plants and −20 for C 4 plants (Chikaraishi et al, 2004). Because the carbon isotopic compostions of C 3 and C 4 plants are offset from one another, the δ 13 C of terrestrial plant waxes in marine sediments can be interpreted using a two end-member mixing model reflecting the relative inputs of C 3 and C 4 plants.…”

“…δ 13 C values for the C 30 alkanoic acid (hereafter δ 13 C 30 ) range from −21 to −27 , reflecting contributions from both C 3 and C 4 plants throughout the region (Rieley et al, 1991(Rieley et al, , 1993Collister et al, 1994;Chikaraishi et al, 2004). …”

“…In order to quantify the relative contributions of C 3 and C 4 plant waxes to the total observed carbon isotopic composition for the C 30 alkanoic acid at different sites, we have defined a two endmember model with the δ 13 C of C 3 and C 4 n-alkanoic acids as −38 and −20 , respectively (Chikaraishi et al, 2004). These isotopic compositions are intended to be representative rather than absolute, as n-alkanoic acids from both C 3 and C 4 plants exhibit a range of isotopic compositions (e.g.…”

We have determined the accumulation rates and carbon isotopic compositions (δ 13 C) of longchain (C 24 -C 32 ) terrigenous plant wax fatty acids in 19 surface sediment samples geographically distributed throughout the Arabian Sea in order to assess the relationship between plant wax inputs and the surrounding monsoon wind systems. Both the accumulation rate data and the δ 13 C data show that there are three primary eolian sources of plant waxes to the Arabian Sea: Africa, Asia, and the Arabian Peninsula. These sources correspond to the three major wind systems in this region: the summer (Southwest) monsoon, the winter (Northeast)

This study comprises an innovative approach based on the combination of chromatography (analytical pyrolysis and pyrolysis compound-specific isotope analysis (Py-CSIA)), light stable isotopes, microscopy and mineralogy analyses to characterize the internal layering of coralloid speleothems from the Ana Heva lava tube in Easter Island (Chile). This multidisciplinary proxy showed that the speleothems consist of banded siliceous materials of low crystallinity with different mineralogical compositions and a significant contribution of organic carbon. Opal-A constitutes the outermost grey layer of the coralloids, whereas calcite and amorphous Mg hydrate silicate are the major components of the inner whitish and honey-brown layers, respectively. The differences found in the mineralogical, elemental, molecular and isotopic composition of these distinct coloured layers are related to environmental changes during speleothem development. Stable isotopes and analytical pyrolysis 3 suggested alterations in the water regime, pointing to wetter conditions during the formation of the Ca-rich layer and a possible increase in the amount of water dripping into the cave. The trend observed for δ 15 N values suggested an increase in the average temperature over time, which is consistent with the so-called climate warming during the Holocene.The pyrolysis compound-specific isotope analysis of each speleothem layer showed a similar trend with the bulk δ 13 C values pointing to the appropriateness of direct Py-CSIA in paleoenvironmental studies. The δ 13 C values for n-alkanes reinforced the occurrence of a drastic environmental change, indicating that the outermost Opal layer was developed under drier and more arid environmental conditions.
