Indian summer monsoon variability and vegetation changes in the core monsoon zone, India, during the Holocene

We present the results of sediment texture, δ 13 C values, TOC, TN, TOC/TN, and magnetic susceptibility (χ lf ) of a 1.54-m deep sediment trench recovered from the core monsoon zone (CMZ) of central India, to understand the paleovegetational history and Indian summer monsoon (ISM) variability during the Holocene. The lower δ 13 C values, TOC/TN ratio, and magnetic susceptibility (χ lf ) from ~11.4 to 9.5 ka BP suggest enhanced ISM intensity, which is well correlated with other available ISM records from both terrestrial as well as marine archives. A gradual stepwise expansion of C 4 plants during ~8.1 and 6.3 ka BP, ~6.3 to 4.7 ka BP, and ~3.0 to 2.0 ka BP suggests a gradual weakening of ISM. The highest δ 13 C values (–18.7‰) recorded at ~2.0 ka BP indicate the dominance of C 4 plants suggesting the weakest phase of ISM in the study area. The expansion of C 3 plants from ~2.0 to 1.6 ka BP indicates a sudden increase in ISM intensity. Subsequently, three stages of enhanced ISM have been recorded between ~1.6 and 0.93 ka BP, ~0.76 and 0.42 ka BP, and ~0.28 ka BP to present
