This is a photographic overview of the features at Cape Liptrap, Victoria, part of the second year unit ESC2111 field excursion. |
General sedimentary layering: sandstone-shale, dipping nearly vertically |
Undulations at the base on sandstone layer in contact with shale: load cast |
Load cast at base of sandstone |
Load cast and slickenlines on layer parallel thrust on the lower right hand side |
Ripple marks with flute casts at high angle to the ripples |
Detail of flute casts |
Load cast at base of sandstone, overprinted by joint sets forming a lozenges |
Flute cast, asymmetry indicates paleocurrent from upper right to lower left |
Fold stack |
Anticline. |
Anticline pair, looking down plunge. |
Hinge zones of anticline pair, looking up plunge. |
Slickenlines of quartz with stepping indicative of reverse movement at "Fold stack",indicative of slip along bedding planes during folding. |
Same as previous. |
Thrust. |
Sandstone repetition indicative of reverse movement. |
Quartz veins along sandstone layer. |
Quartz veins along boudinaged sandstone layer. Notice more veins in boudin necks. |
Folding and reverse faulting of the thicker sandstone layers. |
Folding progressing into reverse faulting. |
Thrusting of sandstone layers on the limbs of folds. |
