Three sections of rock core are shown in Fig. 4.32.The rock comes from near Cumberland, RI, and is called Corbormite (Capt. James T. Kirk, personal communication,2007).The length of the first (top) run is 56 in. and the computed RQD is 82%. For the second run (middle), a length of 60 in. was recovered and the RQD is 100%. Finally, the third run (bottom) is also 5ft long and the ROD is 95%. Verify that the calculated ROD values for the top and bottom runs are correct.
