  abstract = {{T}he comprehensive kinematic analysis of the {V}ariscan fold nappes and associated wildflysch in the {S}outheastern {M}ontagne {N}oire shows that the nappes were thrust northeastwardly along the {C}evennes fault as a result of strike-slip-dominated sinistral transpression between 340 and 323 {M}a. {M}acro- and map-scale recumbent folding and nappe stacking were achieved by {ENE}-directed, strike-parallel thrust shearing. {T}he recumbent folds evolved into sheath folds by interplay of continued strike-parallel thrust shearing and strike-normal shortening manifested by north-verging folds that grew during wildflysch sedimentation. {T}hese results call for a tectonic reassessment of the southern side of the {V}ariscides. {T}he foreland basin was decoupled from the hinterland along orogen-scale sinistral fault(s) trending at a high angle to the orogenic trend, which interacted with a variety of hinterlandward thrust systems. {T}he shift from sinistral transpression to dextral transtension along the {C}evennes fault after 317 {M}a accompanied the closure of the {I}berian-{A}rmorican syntax by accommodating northeastward escape and gravitational collapse of the northern limb of the syntax. {T}hese results illustrate the impact of the shift from plate convergence-controlled to escape-controlled kinematics on shear sense reversal and lower crust exhumation along long-lived strike-slip fault systems.},
