A total of 40 samples from carbonates and 8 samples from silicate rocks were analyzed from the Sangan iron skarn deposit to examine behavior of the oxygen and carbon isotopes. The higher values of ?18O are from metamorphic calcite and dolomite and lower ones are from granitic rocks. Although the ?18O and ?13C values of calcite and dolomite in marble yield the highest values in the Sangan deposi...

Metamorphic viruses transform their code as they propagate, thus evading detection by static signature-based virus scanners, while keeping their functionality. They use code obfuscation techniques to challenge deeper static analysis and can also beat dynamic analyzers, such as emulators, by altering their behavior. To achieve this, metamorphic viruses use several metamorphic transformations, in...

the sargaz granitic intrusion has been emplaced in sargaz ophiolitic suite, south-east of sanandaj-sirjan metamorphic zone, south of kerman province. the central part of the intrusive body contains pinkish coarse-grained granite, but the fractured northern part, neighboring chah-mazraeh fault, has been subjected to pervasive na-metasomatism and related subsolidus reactions. in the northern alte...

Matrices often represent important information in scientific applications and are involved in performing complex calculations. But systematically testing these applications is hard due to the oracle problem. Metamorphic testing is an effective approach to test such applications because it uses metamorphic relations to determine whether test cases have passed or failed. Metamorphic relations are...

Carbonated ultramafic rocks (i.e., ophicarbonates) form by peridotite serpentinization and carbonation at the seafloor. Their metamorphic evolution is linked to that of serpentinites, hence dating deformation metamorphism in ophicarbonates will add constraints P-T-t history subducted lithosphere. A potential, yet underexplored, suitable mineral for geochronology perovskite (CaTiO3). We present ...

Metamorphic testing enables the generation of test cases in the absence of an oracle by exploiting relations among different executions of the program under test, called metamorphic relations. In a recent survey, we observed a great variability in the way metamorphic relations are described, typically in an informal manner using natural language. We noticed that the lack of a standard mechanism...

There are two fundamental limitations in software testing, known as the reliable test set problem and the oracle problem. Fault-based testing is an attempt by Morell to alleviate the reliable test set problem. In this paper, we propose to enhance fault-based testing to alleviate the oracle problem as well. We present an integrated method that combines metamorphic testing with fault-based testin...

Eclogites from the Tian Shan high-pressure/low-temperature (HP/LT) metamorphic belt show evidence for successively increasing metasomatic alteration with increasing retrograde, blueschist-facies overprint. To constrain the source(s) of the metasomatizing fluid and to evaluate elemental and isotopic changes during this overprint, two sequences of eclogiteblueschist transitions were investigated:...

a detailed study of the exploited geothermal field of travale in italy was conducted using magnetotelluric (mt) data in 2004. this paper detects the main features of the conductivity structures of this area. for subsurface mapping purpose, the long period natural-field mt method proved very useful. for processing and modeling of the mt data, 2d inversion schemes were used and to have the best p...
