Abstract

Shows that for `Mytilus trossulus,' skeletal Magnesium/Calcium (Mg/Ca) ratios provide an accurate measure of temperature and weekly sea-surface temperatures Which may be estimated with an apparent accuracy of approximately +\-1.5 degress Celsius. Sample collection and analysis; Details shell dating; Ratios of skeletal Mg/Ca; How seawater temperature influences the Mg regulatory mechanism in skeletal calcite of Mytilus trossulus.

6. Closed-system marine burial diagenesis: isotopic data from the Austin Chalk and its components.

Author

Czerniakowski, Lana Ann, Lohmann, Kyger C., and Wilson, James Lee

Subjects
*CARBON composites, *DIAGENESIS, *SEDIMENTOLOGY, *CEMENTATION (Petrology), *CALCITE, *GEOLOGY
Abstract

Examines the carbon and oxygen isotopic composition of the Austin Chalk in order to document the effects of burial diagenesis on carbon and oxygen-isotopic composition. Analysis of low magnesium calcite oysters to estimate the starting composition of Cretaceous marine sediment; Compositions of micrite, intergranular and fracture cement; Minor variation in composition of micrite.
