Sedimentary rocks are the commonest rocks found on the surface of the Earth’s crust and record much of the history of both our planet and life on Earth. This chapter describes how to draw outcrops of sedimentary rocks in the field and the most important features of these rocks to record and describe. The stratigraphy and interpretation of sedimentary rocks is also considered in the chapter and includes a description of common sedimentary structures. The use of sedimentary facies in evaluation of depositional environment is introduced. Five worked examples of field sketches of sedimentary outcrops are given to illustrate how to make accurate and detailed observations of sediments. Examples include how to draw unconformities, sedimentary structures, lithologies, and graphic logs.

Partial Success

In the VELA UNIFORM Special Issue I of Geophysics, M. N. Toksöz presented the result of his attempt at determining the shallow structures of the earth’s crust from the phase velocity of microseisms. He stated that his attempt resulted only in partial success on account of the fact that the microseisms arrived from more than one direction at the same time with comparable strength. He also concluded that there was no way of improving the results by the use of special arrays because, according to him, there were two unknown parameters, direction and phase velocity, and without the knowledge of one the other cannot be found. I thought this problem was already solved in my paper (Aki, 1957), in which a statistical theory of determining the phase velocity of random waves was given with a successful application to microseisms in Tokyo in the frequency range of 5 to 15 cps. Since Toksöz’s conclusion might have given a pessimistic view on the use of microseisms, I feel it is necessary to report a brief summary of my old paper published in a Japanese journal which might not be well circulated in the United States.

Sophisticated Technology

The distance from the Earth’s surface to the centre of its core is 6,370 kilometres. Humans have penetrated—with difficulty, and the help of sophisticated technology—to a little more than 4 kilometres below ground; and to a depth of 12 kilometres, probing with boreholes. That does not even get us through the Earth’s crust, so what lies in the gigantic realm of the Earth’s depths? ‘Deep Earth geology’ considers the different areas of study of the Earth’s interior, including petrology—the study of igneous, metamorphic, and sedimentary rocks—and magma studies that provide the tangible evidence of the Earth’s history. It also discusses seismology, geophysics, magnetism, and structural geology.
