Mineralogical and biological controls on the Fe/Ca and Mn/Ca ratios of lacustrine carbonate allochems
(Elsevier, 1983-01)
The Fe/Ca and Mn/Ca ratios of lacustrine carbonate allochems are primarily controlled by the mineralogy of the carbonate polymorph. However, these ratios are subject to a significant degree of biological control among ...
Characterization of sedimentary humic matter by alkaline hydrolysis
(Elsevier, 1983)
Humic matter fractions from modern sediments of Lake Huron and Lake Michigan have been compared. Large yields of saccharinic acids from alkaline hydrolysis suggest that these fractions contain large portions of carbohydrate ...
Photochemistry of methane in the Earth's early atmosphere
(Elsevier, 1983-06)
A detailed model is presented of methane photochemistry in the primitive terrestrial atmosphere along with speculation about its interpretation. Steady-state CH4 mixing ratios of 10-6-10-4 could have been maintained by a ...
Late Cretaceous and Paleogene tectonic evolution of the North Pacific Ocean
(Elsevier, 1983-10)
The Late Cretaceous history of the northern Pacific Ocean has not been adequately deciphered, largely because a major plate reorganization occurred during the Cretaceous magnetic quiet interval. Using primary data to ...
