Understanding the variations of Indian monsoon and East Asian monsoon could improve the prediction accuracy of monsoon and regional rainfall. Unfortunately,among those high resolution paleoclimatic records from the two monsoon areas, few of them could provide comparable records with clear climate information, which makes it difficult to compare the two monsoon systems and to understand the difference of their driving forces. In this study, a high resolution rainfall sequence has been established during the Early-Middle Holocene by two stalagmite oxygen isotope records with precise chronology from the south and the north of Oman respectively and the Indian monsoon rainfall was compared with the East Asian monsoon rainfall at the same period. Reconstructed rainfall is robust to the uncertainty from the speleothem chronology and from the delta~(18)O records in various stalagmites from the same cave. It could be revealed that the rainfall in Oman is generally increasing with fluctuations during 9.6~6.0ka B.P. The rainfall increased during 9.6~8.5ka B.P., 8.0~7.6ka B.P.,7.3~6.9ka B.P. and 6.6~6.2ka B.P.,while rainfall reduced during 8.5~8.Oka B.P.,7.6~7.3ka B.P., 6.9~6.6ka B.P. and 6.2~6.0ka B.P. The results suggest that the rainfall in Oman coincide with the the rainfall from Southwest China during the same period. Weak ENSO during the Early-Middle Holocene might be one of the reasons causing their similarity as the impacts of ENSO on the two monsoon systems are different. Strong ENSO influence could result in different between the two systems, and weak ENSO with less influence might lead to less difference between them. Therefore, ITCZ moving driven by insolution should be the main reason leading to the rainfall variation synchronously in both Oman and Southwest China.
