The metamorphic sole rocks at the base of mantle peridotites from the Mersin ophiolite consist of amphibolites and metasedimentary lithologies. Mineral parageneses in the metamorphic sole rocks exhibit amphibolite and greenschist facies assemblages. Geothermobarometric studies based on mineral assemblages and chemical compositions of minerals indicate that average metamorphic temperature during...

The structure and distribution of organic sulfur in coals of different rank and different sulfur content were studied by combining mild organic solvent extraction with XPS technology. The XPS results have shown that the distribution of organic sulfur in coal is related to the degree of metamorphism of coal. Namely, thiophenic sulfur content is reduced with decreasing metamorphic degree; sulfoni...

CHI-SQUARED DISTANCE AND METAMORPHIC VIRUS DETECTION by Annie H. Toderici Malware are programs that are designed with a malicious intent. Metamorphic malware change their internal structure each generation while still maintaining their original behavior. As metamorphic malware become more sophisticated, it is important to develop efficient and accurate detection techniques. Current commercial a...

Challenges arise in testing applications that do not have test oracles, i.e., for which it is impossible or impractical to know what the correct output should be for general input. Metamorphic testing, introduced by Chen et al., has been shown to be a simple yet effective technique in testing these types of applications: test inputs are transformed in such a way that it is possible to predict t...

Abstract High-grade metamorphic rocks and crustal melts provide crucial evidence for growth differentiation of the continental crust, are widespread in collisional orogens. However, their importance evolution arcs remains poorly understood. Metamorphism related anatexis preserved margin Neo-Tethys ocean serves as a key natural laboratory to investigate this process. Along Neo-Tethyan arc margin...

Although fluid inclusions were apparently known to early naturalists, actual research on fluid and melt inclusions began only in the mid-1800s and grew very slowly for the next 100 years. Russian scientists began systematic studies of inclusions in the 1930s, but it was not until about 1960 that publications mentioning or using fluid inclusions began to increase from a few each year to the pres...

Structural field relations, petrologic and geochemical studies, and radiometric age aualysis of metamorphic rocks at the base of the Brooks Range ophiolite provide a record of the time, tectonic setting, and initial conditions of ophiolite emplacement during the Middle Jurassic western Brookian orogeny. The metamorphic sole of the Misheguk, Siniktanneyak, and Avan Hills ophiolite bodies is tran...

To study the ontogeny of the vasotocin (VT) system and its contribution to anuran metamorphosis, VT mRNA levels were determined by Northern blot analysis in metamorphosing bullfrog tadpoles. Effects of osmotic stimulation on VT mRNA levels were also analyzed in order to follow the development of osmotic responsiveness of VT neurons. The intensity of hybridization signals for VT mRNA gradually i...

Cerro El Toro, a Pliocene scoria cone that carried abundant lower crust xenoliths to the surface, is located in Mesa Central (MC), Mexico, where mafic alkalic intra-plate volcanism has occurred since early Miocene (end of Sierra Madre Occidental volcanism). Early studies Toro showed feldspathic granulite equilibrated at P = 0.9–1.4 GPa and T 900−1100°C under anhydrous conditions (ternary feldsp...
