Figures were developed to justify fault movement and an insight into alluvial fan sediment. These are good examples of the type of figures GIX are and can produce for our clientele.
The left-hand figure displays the changes in topography over the past two decades, possibly from fault displacement (throw only), therefore any area which shows a change along a lineation could be a fault. Additionally, there are changes in alluvial fan topography, potentially linked to erosion or deposition
The right-hand map, shows how Landsat 8 OLI can be used to do large scale mapping and categorising. This figure is using hydrothermal identification to determine large scale geological faults and alluvial fans (RGB 4/6: 4/2: 6/5). Any noticeable changes in ratio were then mapped, Linear features being recognised as faults and fan shaped features as alluvial fans. Any changes in colour on the alluvial fan can be different sediment from different sources which can be connected or showing different ages of alluvial fan.
