Through geologic dating methods (discussed in another lab), it has been determined that the offset in Wallace Creek shown in Figure 4 is 3,700 years old. The length of the offset is 123 m. How fast are the plates
moving along the San Andreas Fault in cm/yr?

15 points need quick 1. looking at your graph and the geologic time scale during what period did this rock form? what is the age span of the rock, in millions of years? 2. this rock sample is limestone and shale. with what you know about rock formation, what type of environment did these organisms live in? 3. if some of these fossil samples were found in a rock also containing leaf fossils, could you use radiocarbon dating to determine the age of this rock? explain.
