... zooxanthellate coral communities to constrain and model paleo-salinities of marginal-marine waters of the Miocene Lorca Basin, Spain. Salinities ranged from 22 to 32 PSU during growth of coral bioherms and carpets of the Soriana and Parrilla formations, and from 35 to 39 PSU during deposition of the Hondo...

.... The formation of orogenic Au deposits began in the Late Cretaceous, and they kept forming into the Eocene as compressional tectonics progressed. The formation of porphyry-type, sulfide skarn, and epithermal deposits continued during the Eocene, and followed the eastward progression of the magmatism...

... of the retrograde skarn suggest equivalent δ 18 O fluid values (9.1–12.0‰). These heavy δ 18 O values indicate that the mineralizing fluids equilibrated with deep crustal rocks, with no significant input of surficial waters, even during the formation of the retrograde skarn. The Sr and Nd radiogenic isotope data...

It has been debated whether or not this type of decadal-scale redistribution of heat is related to the greenhouse warming of the earth‘s atmosphere ( Parker, 1996 ; Watts and Morantine, 1991 ).
