This paper discusses the method of interpretation of high—resolution sequence stratigraphy atconventional seismic profiles through an analysis of a vast amount of seismic information obtainedfrom the east part of the Tarim Basin．By means of this method the Carboniferous System in theeast part of the Tarim Basin can be divided into three sequences(C I，CⅡ，CⅢ)and six systemtracts(C I TST，C I HST，C I TST，CⅡHST，CⅢsMsT，CⅢTST)．The cI sequence was deposited un—der the conditions of the rapid rise of sea level and the rapid compensation of considerable terrige—nous clastie materials．the C I sequence was deposited when the sea—level rise velocity became slowand the recharge of terrigenous materials was relatively stable·and the CⅢsequence was deposit—ed when the sea—level rise velocity became rapid and the recharge of terrigenous materials becameslow．
