WebAs sediments continue to be deposited, burying the ooze (remember burial is vital to preservation!), the weight of the overlying sediment will cause an increase in temperature and pressure, which will, in turn, lithify the ooze (i.e., turn it into stone) and convert the organic material into kerogen and ultimately oil and natural gas. WebWith question such as these clearly before them, the scientists aboard the Glomar Challenger processed to the Mediterranean to search for the answers. On August 23, 1970, they recovered a sample.
