The Paleotopography Reconstruction of late Cretaceous Dabie Orogen by Low-Temperature Thermochronological Age-Elevation Relationships
Dabie Orogen Low-Temperature Thermochronology Paleotopography
2011/12/20
The paleotopography reconstruction of orogen has an important research value on the study of mountain building and the study of orogen’s regional control over the paleoclimate change. Considering the ...
Characterization method of Limestone according to the Formation Age on manufacturing process of aragonite precipitated calcium carbonate
Characterization method Limestone the Formation Age manufacturing process aragonite calcium carbonate
2012/3/28
Korea has about 68 hundreds million tons of limestone's reserves. Still, high-Ca2+ limestone containing more than 52% calcium oxide makes up for about 12% only; hence the need for securing and effecti...
Manufacturing Characteristics of Precipitated Calcium Carbonate according to the Formation Age of Limestone
Manufacturing Characteristics Precipitated Calcium Carbonate Formation Age Limestone
2012/3/28
Limestone is abundant mineral that has occupied about 14% of the earth's crust and 20~30% of the sedimentary rock all over the world. As extensive distribution, limestone contains various minerals suc...
Smectite Illitization in Pliocene-Age Gulf of Mexico Mudrocks
Clay Diagenesis Core Analysis Gulf of Mexico Illite Smectite TEM XRD
2011/12/1
Abstract: Utilizing high-resolution transmission electron microscopy (TEM), energy-dispersive spectroscopy (EDS) and X-ray diffraction (XRD) techniques, we have studied the transition from shallower s...
Stable Isotope Geochemistry of Kaolinite from the “White Section,” Black Ridge, Clermont, Central Queensland: Implications for the Age and Origin of the “White Section”
Inversion Isotopic exchange Kaolinite Late Triassic Low δD Weathering
2011/12/29
Kaolinite from the Black Ridge, Clermont, has relatively low δ18O (12.3‰ to 14.8‰) and very low δD values with a large variation (−120‰ to −85‰). Comparison of these data with those from t...
Considerations and Applications of the Illite/Smectite Geothermometer in Hydrocarbon-Bearing Rocks of Miocene to Mississippian Age
Geothermometer Hydrocarbons Illite/smectite Illitization Smectite diagenesis Thermal maturity
2011/12/29
Empirical relationships between clay mineral transformations and temperature provide a basis for the use of clay minerals as geothermometers. Clay-mineral geothermometry has been applied mainly to dia...
Comparison of Clay and Zeolite Mineral Occurrences in Neogene Age Sediments from Several Deep Wells
Analcime Geothermal temperature Illite Diagenesis Smectite Zeolite
2012/1/9
Clay and zeolite mineral assemblages were determined for five deep wells in volcano-clastic sediments (Japan) and for one well in mudstones (California). The clay mineral suites in these wells showed ...
K/Ar Systematics of an Acid-Treated Illite/Smectite: Implications for Evaluating Age and Crystal Structure
Acid dissolution Age dating Glauconite Illite/smectite Interstratification Ordering Potassium
2012/1/12
On the basis of progressive acid dissolution the Thompson-Hower model states that mixed-layer glauconite/smectite and illite/smectite contain potassium in two structural sites: a mica-type K position ...
Goyazite in Kaolinitic Altered Tuff Beds of Cretaceous Age Near Denver, Colorado
Diagenesis Goyazite Kaolinite Phosphorus Volcanic ash
2012/2/7
A hydrated alumino-phosphate mineral was identified in thin, kaolinitic clay beds of the Cretaceous Dakota Group and the overlying Mowry Shale in the Dakota hogback west of Denver, Colorado. It occurs...
