Incremental Growth of Composite Clastic Dikes
Incremental growth of a sheeted clastic dike occurs over time, megaflood by megaflood. The figure above shows the growth of a composite...
Truncations Control Clastic Dike Geometry
Truncations control dike width and apparent taper direction. What appears to be an upward-tapering, upward-injected clastic dike sourced...
Clastic Dikes Form Polygonal Networks
Networks of Pleistocene clastic dikes are sometimes visible on bladed slopes or surfaces that have had all vegetation removed. Aerial...
Evidence for Long Periods Between Fillings in Sheeted Clastic Dikes
Crosscutting relationships establish the order of events in a sheeted clastic dike exposed near TriCities, WA. 1.) Injection of yellow...

Flood and Slide Deformed Deposits - Priest River, ID
The Ice Age floods inundated the southern portion of the Priest River Valley in northern Idaho, though this area is rarely mentioned in...
Are dates on carbonate cements in Pasco Basin regionally relevant?
Uranium-thorium is a radiometric technique for dating carbonates. Paces (2014) estimated the ages of secondary carbonate cements in the...
Flood Count Controls Clastic Dike Width in Columbia Basin, WA-OR-ID
Pleistocene age clastic dikes in the Columbia Basin, WA grew incrementally by repeated injection of sediment into cracks. Injected...
