the massive sulphide deposit at kantienpan cu-zn mine is hosted by volcano sedimentary succession known as the areachap group, in the eastern part of namaqua metamorphic province, south africa. the deposits were affected by a complex deformation and metamorphic history and represent examples of upper amphibolite to granulite grade metamorphosed volcanic-hosted massive sulphide (vhms) depo...

Most of the organic nitrogen (Norg) on Earth is disseminated in crustal sediments and rocks in the form of fossil nitrogen-containing organic matter. The chemical speciation of fossil Norg within the overall molecular structure of organic matter changes with time and heating during burial. Progressive thermal evolution of organic matter involves phases of enhanced elimination of Norg and ultima...

The Chadegan metamorphic complex is a WNW-ESE- trending antiformal structure located in Sanandaj-Sirjan structural zone, Iran.The inner core of the structure is made of orthogneiss, containing eclogitic lenses. Schists and marbles lie structurally above theorthogneiss and crop out in the external limbs of the antiformal dome. Two main deformational episodes have been documented in theschists an...

a r t i c l e i n f o a b s t r a c t Abstract interpretation Program semantics Metamorphic malware detection Self-modifying programs Metamorphic code includes self-modifying semantics-preserving transformations to exploit code diversification. The impact of metamorphism is growing in security and code protection technologies, both for preventing malicious host attacks, e.g., in software divers...

n October 1995, a four-day multi channel seismic and bottom sampling survey was conducted aboard the R/V Ewing in the Pacific’s western Woodlark Basin. This site augmentation effort, supported by USSSP, was associated with JOIDES Proposal #447. New data from this survey provide further evidence for active extension on a low-angle (~25) normal fault but do not support a metamorphic core complex ...

Absence of test oracles is the grand challenge for testing complex scientific software. Metamorphic testing is the novel technique for developing test oracles on metamorphic relations. Although it is easy to find metamorphic relations based on general guidelines and domain knowledge, the ones that can adequately test the software are difficult to be developed. This paper introduces a machine le...
