The thoughtful paper in 1893 by J. H. L. Vogt, of Norway, on injected igneous deposits derived from an igneous source by the process of magmatic differentiation, which was also advanced to account for hot mineralizing waters, drew attention once more to the earlier ideas of Elie de Beaumont. Then came the classical paper by Franz Posepny on ...Research in the area of siliciclastic diagenesis has historically incorporated advances in related disciplines such as petrography and petrophysics, mineralogy, geochemistry, organic geochemistry, stratigraphy and basin analysis, and more recently, fluid flow.COHESIVE STRENGTH IMPROVEMENT MECHANISM OF KAOLINITE NEAR THE ANODE DURING ELECTROOSMOTIC CHEMICAL TREATMENT.

Experimental determination of quartz solubility in H 2 O-CaCl 2 solutions at 600–900 °C and 0.6–1.4 GPa. Structures and transport properties of supercritical SiO 2 -H 2 O and NaAlSi 3 O 8 -H 2 O fluids. The use of boron nitride to impose reduced redox conditions in experimental petrology. Hydrous wadsleyite crystal structure up to 32 GPa.Continental arcs are favorable sites for porphyry Cu ± Mo deposits. In contrast, the Jurassic Zhangguangcai-Lesser Xing’an continental arc, northeastern China, hosts numerous porphyry Mo deposits with only minor total Cu endowment.With the beginning of seismology as a science in the 19th century, many scholars devoted time to reporting luminosities associated with earthquake activity.Parts of northern Zealandia were transiently uplifted and then subsided. IODP Site U1506 on northern Lord Howe Rise rose close to sea level with a shallow carbonate platform at ca. 50 Ma, and subsided to a bathyal environment (∼600 mbsl) by 45 Ma.

Lithium isotopes show great potential to trace Earth surface processes due to the large mass discrimination between 6 Li and 7 Li associated with clay uptake. However, factors controlling the Li isotopic composition (δ 7 Li) of river water, especially those with a water-bedrock δ 7 Li difference higher than that of the equilibrium fractionation …Seismic stratigraphy is the study of stratigraphy and depositional facies as interpreted from seismic data. Seismic reflection terminations and configurations are interpreted as stratification patterns, and are used for recognition and correlation of depositiona' sequences, interpretation of depositional environment, and estimation of lithofacies.
