Numerical simulation of viscoelastic buckle folds: Implications for stress, fractures, porosity and fluid flow
<p>"Over the past several decades, buckle folds have been exclusively studied by numerous methods. However, lots of assumptions and simplifications are made, which may not result in realistic in-situ stress conditions leading to rock failure. This study represents the first numerical simulation of …

Progressive deformation, fluid flow and water-rock interaction in the Mexican Fold-Thrust Belt, Central Mexico
… (a more brittle behavior), and mesoscopic buckle folds and associated cleavage dominate deformation in the basinal carbonates (a more ductile behavior). Two phases of deformation are recognized, the first, D1 being more intense than the second, D2. The difference in facies distribution is …

Cross-structural development at the southwestern termination of Walker Mountain, Virginia
… mesoscopic solution cleavage and associated buckle folds are obliquely superimposed on the regional northeast structural trend. Values of penetrative strain, determined from syntectonic fibrous mineral growths in pressure fringes, vary along strike and vertically within the thrust sheet and …

Thrust sheet evolution in the Kinlochewe region of the Moine Thrust Zone, N.W. Scotland and the Pelvoux-Brianconnais, French Alps
… movement within thrust sheets. Fault-bend folds (structurally necessary folds) have developed following slip of thrust sheets across irregular thrust surfaces and buckle folds have grown during shortening within the sheet. Extensional fault sheets (surge zones) can be mapped out in the …

Kinematics and dynamics of salt tectonics in the Paradox Basin, Utah and Colorado : field observations and scaled modeling
… diapirs rose actively. Reverse faults and buckle folds formed in the roof above the diapirs. Salt withdrawal and dissolution formed a fault-bounded trough in the overburden above a vanishing diapir. The trough profile was a mirror image of that of the initial diapir and had inner …

Origin of Periclines in the Ozark Plateau, Missouri: A field and numerical modeling
"A series upright sub-horizontal folds in sandstones of the early Ordovician Roubidoux Formation are exposed in road cuts along US Highway 63 in the northern part of the Salem Plateau of central Missouri for over a distance of approximately 10 km. These folds are in marked contrast to the more …
