the study area is located south of ghonabad in eastern iran. this area is situated between two major faults, darouneh to the north and dashtbyaz to the south. the movements of these faults cased major dislocation of this block. najmabad granodiorite to granite batholith is elongated trending east-west 2×8 km2. mineralization is associated with granite and monzonite. alteration zones are: propyl...

In order to reveal the metallogenic potential of Indosinian Ziyunshan granite in central Hunan, temporal, spatial and genetic relationship between mineralization is discussed, concentrations ore-forming elements for different granites are measured. The geochemistry elements, isotope chronology, data derived from analysis on Au-W deposit area compared with geologic features regional rock. result...

Small samples of rock, like those used in laboratory collision experiments, are known to be much stronger than bodies that are meters to hundreds of meters in size [1]. Specifically, the impactor energy per unit target mass needed to shatter the target decreases dramatically with increasing target size. This occurs because the strength of rock, like many other geological materials, depends stro...

Three techniques of holographic Interferometry were developed to study the response of geological materials to propagating stress waves. Two of these techniques, stored-beam Interferometry and double-exposure Interferometry, were found effective when applied to studying smallamplitude wave propagation. The third technique, a form of time-average holographic Interferometry (which produces fringe...

Recent zircon-based geochronological investigations in the Adirondack Mountains, in the state of New York, demonstrate that 1155 ± 6 Ma massif anorthosite was emplaced during the post-contractional phase (1160–1140 Ma) of the ca. 1200–1140 Ma Shawinigan orogeny. Emplacement of many other anorthosite – mangerite – charnockite – granite (AMCG) suites also correlates with the waning stage of oroge...

Extensive export quality reserves of granite, dolerite and marbles which are used for interior decorations as wall facing, paving floors, kitchen counter tops, etc., are available in Azad Kashmir. Since these stones contain radium in trace amounts, therefore, its use as a building material may be a potential source of indoor radon. In order to assess health hazards due to the use of these stone...
