GEOLOGY 3430 - INTERPRETATION OF SOURCE AREA Homework #3 Due Feb. 12th Part II – Grain Size Distribution Now that you have determined grain size for several locations in the Green River Basin, you will be given size information for additional localities and learn how to construct a map that shows the spatial distribution of grain size (a contour map of grain size). You will use this to make interpretations about where sediment source areas were located. The Pass Peak Formation was deposited in the Hoback Basin of western Wyoming during Eocene time. The mountain belts that you see on the map (Gros Ventre and Wind River Ranges) were rising at the time of deposition. To the west of the basin is the Wyoming thrust belt; however, tectonic activity there appears to have predated deposition of the Pass Peak Formation. Data: You are provided with a base map of most of the outcrop area of the Pass Peak Formation with 46 sample localities plotted on it. For each locality, the following are provided:
