The Neutron Radiography Reactor at Idaho National Laboratory (INL) has two beamlines extending radially outward from the east and north faces of reactor core. control rod withdrawal procedure recently been altered, potentially changing power distribution thus properties neutron beams, calling for characterization beams. East Station involved experiments used to measure following characteristics...

The Elatsite–Chelopech ore field in the northern part of Panagyurishte district Central Bulgaria comprises numerous spatially associated porphyry copper and epithermal gold deposits prospects. In addition to mineralization alteration features, trace elements, lead sulfur isotope signatures sulfide minerals from copper, base metal gold-base deposits/prospects have been studied. LA-ICP-MS analyse...

The Harla gold deposit is located on the eastern segment of Kanggur-Huangshan ductile shear belt in Eastern Tianshan, southern margin Central Asian Orogenic Belt. orebodies show close spatial association with NEE-trending faults and are hosted volcanic rocks Lower Carboniferous Xiaorequanzi Formation. Three mineralization stages were recognized: an early stage characterized by specularite–pyrit...

The Vathi porphyry Cu-Au ± Mo mineralization is located in the Serbo-Macedonian metallogenic province of Western Tethyan Metallogenic Belt. It mainly hosted by a latite and genetically associated with quartz monzonite intrusion, which intruded basement rocks Vertiskos Unit latite, 18 to 17 Ma ago. A phreatic breccia crosscuts latite. was affected potassic alteration, whereas subjected local pro...

Introduction: Gamma ray and neutron spectrometers in orbit around Mars have revolutionized our views of the present distribution of water ice and hydrogenous minerals [1,2]. In particular, hydrogen enhancements (expressed as water equivalent hydrogen, or WEH) at lowand mid-latitudes could potentially be related to comparatively recent climate change on Mars. The identification of glacial landfo...

A method of epithermal neutron activation analysis for uranium and thorium is discussed in relation to other rapid analytical methods for these elements. Caledonian granites are divided into four main groups on the basis of U and Th contents: (a) a group of evolved late granites with high U and Th contents and high Th/U ratios, (b) a group of uranium-enriched mineralized granites, (c) granites ...
