  abstract = {{D}uctile to brittle extensional deformation following thrusting of the peridotites nappe during the {U}pper {E}ocene has been shown to play a major role in the {T}ertiary tectonic evolution of the northern part of the main island of {N}ew {C}aledonia and its eastern and western margins. {I}n this study, we provide new tectonic data from southern {N}ew {C}aledonia that allow to better constrain the tectonic evolution of the southern part of the main island. {W}e present a kinematic analysis of faults and striations obtained mainly from exposures of sedimentary rocks in the region of {N}oumea with complements from measurements made farther north at {N}epoui within post-obduction {M}iddle-{M}iocene deposits. {W}e also present additional results of an interpretation of seismic lines from the lagoon south of the {N}oumea {P}eninsula which provide constraints on the current tectonic regime of southern {N}ew {C}aledonia. {E}xtensional faults in the {N}oumea region have been studied within terranes of various ages including pre- and syn-obduction deposits and ophiolites. {H}ence, we demonstrate that important extensional events have affected the southern part of the {N}ew {C}aledonia block after the obduction of the peridotite nappe. {T}he direction of maximum extension is variable at the scale of the region. {B}oth high angle and low angle normal faults are present and block rotation is observed at some localities. {T}his suggests that detachments accommodating significant displacements are cutting through the sedimentary pile. {T}he average final strain pattern of the region can be regarded as the results of a multidirectional flattening, a hypothesis consistent with vertical uplift associated with regional extension. {T}hese results are in good agreement with conclusions of earlier workers showing late extensional evolution of the ophiolites along},
