The invention relates to a method for identifying low-order unconformity surfaces of carbonate rocks. The method comprises the steps that the unconformity surfaces are identified according to concentration anomaly by measuring the concentration of a strontium (Sr) element in a rock sample. The reason of which concentration anomaly of the strontium is selected to identify and study the unconformitysurfaces is that other indexes including vanadium and nickel are prone to being affected by late diagenesis to cause unexpected changes, but Sr is very stable and cannot migrate due to the late diagenesis, the original sedimentary characteristics of the formation can truly be reflected, and the measurement of Sr concentration is highly operable and accurate. In particular, an irreplaceable role is played in identifying low-order unconformity of carbonate rocks which lack obvious angular contact relationship and biological fossil indicators. Abnormalities of Sr concentration with wider range (>=14 %) can indicate the existence of the unconformity surfaces. The method has the characteristics of obvious characteristics, high sensitivity, accurate conclusion, few interference factors, simpleoperation, time and labor saving, easy judgment, good universality and the like.
