Geosciences Department Citation Style Recommendation
In the geosciences, the Geological Society of America with its two journals --Bulletin of the Geol. Soc. of America --- and Geology--- set the standard for citation of published literature. I have the students in my tutorials follow the GSA standard.
Example:
Johnson, M.E., Rong, J., Wang, "C., and Wang, P., 2001, Continental island
from the Upper Silurian (Ludfordian Stage) of Inner Mongolia: Implicatons
for eustasy and paleogeography: Geology, v. 29, p. 955-958.
