There are two very good books that discuss what a technological civilization, ours, would leave behind in the archaeological – geological record.

They are;

Weisman, A., 2008. The world without us. Macmillan.
0312427905, 9780312427900

and

Zalasiewicz, J. and Freedman, K., 2009. The Earth after us: what legacy will humans leave in the rocks?.
Oxford University Press. 0199214980, 9780199214983

Dr. Zalasiewicz has written a papers about the Anthropocene and the signature and traces that would survive in the geologic record. Examples are:

Zalasiewicz, J., Waters, C.N. and Williams, M., 2014.Human bioturbation, and the subterranean landscape of the Anthropocene. Anthropocene, 6, pp. 3-9.

and

Zalasiewicz, J., Williams, M., Waters, C.N., Barnosky, A.D. and Haff, P., 2014. The technofossil record of humans. The Anthropocene Review, 1(1), pp. 34-43.
