Abstract
The determination of the structure of the oceanic crust has been achieved mainly by indirect methods because the ocean floor is relatively inaccessible and there are limitations to the depths penetrable by drilling (currently about 1 km below the seafloor). Our current knowledge of crustal structure is based on three sources of information: (1) rock samples obtained by submersibles and from oceanic islands, drill core and dredge hauls; (2) geophysical data; and (3) subaerially exposed fragments of ocean crust and upper mantle, that is, ophiolites (Chapter 1).
