RANCANG BANGUN MODEL KOMPRESI DAN TARIK PERMODELAN SANDBOX DAN MANFAATNYA

Abstract

[Design of Compression and Extensional of the Sandbox Model and Its Benefit] Divergent and convergent tectonic sytem can be studied from the sandbox modelling. This model has a axis of movement. Sandbox models itends to study the progress of structural geology such as fault and fold. We successfully made machine of sandbox. This machine has basal detachment from duraluminum. Material for model is taken by loose sand from Ngrayong Formation. This experiment focused to observation about morphology in surface and thrust or backthrust in subsurface. This experiment has compression system. Result of model was that morphological sequences associated with fault sequences. Fault is formed to have the pattern of forward propagating thrust faults. It's caused by imbricate thrust system. Folding is formed by the mechanism of fault propagation folding.
