25 26 The Tropicana gold deposit is located adjacent to the margin of the Yilgarn craton in 27 the Albany–Fraser orogen, Western Australia. The deposit is hosted in granulite facies 28 quartzo-feldspathic gneisses of the Archean Tropicana Gneiss. Ore bodies comprise 29 biotite-pyrite alteration concentrated in shear zones that formed during NE-SW 30 shortening in the late Archean, and clearly p...

[1] The SEA‐CALIPSO experiment in December 2007 incorporated a sea‐based airgun source, and seismic recorders both on Montserrat and on the adjacent sea floor. A high quality subset of the data was used for a first arrival P‐wave velocity tomographic study. A total of more than 115,000 traveltime data from 4413 airgun shots, and 58 recording stations, were used in this high‐ resolution tomograp...

were given 3H-digoxin intravenously 1 hour following acute anterior-wall infarction produced by serial coronary arterial branch ligations. Central and peripheral zones of infarction, ischemic border zones, and nonischemic myocardium were demarcated by epicardial electrode mapping. Two hours after 3H-digoxin administration, animals were sacrificed and epicardial and endocardial samples from each...

introduction the kahang cu- mo deposit is situated approximately 73 km northeast of isfahan. asadi (2007) identified a geological reserve of 40 mt (proven reserve) grading at 0.53 cu, 0.02 mo and estimated reserve of 120 mt. all the rock types in the region have been subjected to hydrothermal solutions which gave rise to three different alteration facies. the dacite and rhyodacite volcanic rock...
