Detailed description of boreholes and analysis of published seismic-reflection profiles from the Elmsvale basin show that syn-sedimentary deformation in the Chaswood Formation resulted in onlap and unconformities. Deformation was concentrated in a syncline bounded on its northwestern side by the Rutherford Road fault. The deformation was probably synchronous along the 15 km length of the fault and might thus provide a basis for stratigraphic correlation. Closely spaced boreholes show that lignite horizons are not widespread stratigraphic markers and that major sandstone units are of more value for correlation. A new correlation from the type section of the Chaswood Formation northeastward along the Elmsvale basin and northwestward to Shubenacadie is proposed. A landslide deposit up to 5 m thick consisting of tilted mudstone blocks can be correlated for 4 km along strike in boreholes along the northern flank of the syncline, providing further evidence for syn-sedimentary deformation, which is a local manifestation of widespread Cretaceous deformation in Atlantic Canada.
