These differences in the physical properties of pelagic calcareous sediments at DSDP sites 504 and 505 are a result of the temperature difference between the two sites. A more rapid decrease in diagenetic potential is favored by increasing sediment temperature. The rates of the diagenetic solution-precipitation reactions are increased because of the higher temperature (Baker et al 1980), and the accompanying increased concentrations of ions involved in cementation (Mottl et... 

Case studies from the Andes and Tibet show how these methods can be used alone or in combination to estimate paleoelevation. In both cases, the potential for diagenetic alteration... 

Manganese Numerous investigations have been made of the coprecipitation of transition and heavy metals with calcite and aragonite. The two elements that have received the most attention are Mn2+ and Zn2+. This attention probably stems from their potential importance for studying diagenetic processes (e.g., Pingitore, 1978).

Organic compounds and water in its various forms (liquid and bound H2O and 0H, both affect, and are affected by, diagenetic processes. VNIR (0.3 - 2.7 jun) reflectance spectroscopy provides a potentially powerful tool for monitoring such diagenetic changes.
