Last glacial to interglacial transition period is a best test case to understand the interplay between Pco2-temperature-chemical weathering when a pulse of rapid chemical weathering was initiated. Here we show, from a high resolution 54 ka record from the Andaman Sea in the northern Indian Ocean, that the chemical weathering responds to deglacial to mid-Holocene summer monsoon intensification in the Myanmar watersheds. The multi-proxy data (Al/K, CIA, Rb/Sr, Sr-87/Sr-86 for degree of weathering and Nd-143/Nd-144 for provenance) reveal an increase in silicate weathering with initiation of interglacial warm climate at similar to 17.7 ka followed by a major change at 15.5 ka. Inferred changes in chemical weathering have varied in tandem with the regional monsoonal proxies (delta O-18(sw)-salinity changes of Northern Indian Ocean, effective Asian moisture content and delta O-18 records of Chinese caves) and are synchronous with changes in summer insolation at 30 degrees N and delta O-18 of GISP2 implying that chemical weathering was not a later amplifier but worked in tandem with global climate change.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Increased chemical weathering during the deglacial to mid-Holocene summer monsoon intensification","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:39.065199","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2017,"MonPub":null,"DateUpdate":"2018-02-15","DateCreate":"2017-03-21","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000396536500001","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/srep44310"},"refs":null,"anarec":{"AnaID":284055,"PubliDate":2017,"Pagination":"11 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"7","Issue":"44310","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
