Introduction: We have studied a terraced fan deposit centered at 15.0° S, 299.7° E within one of the troughs of Coprates Catena in order to investigate the role that water may have played in its formation. Only a handful of these unique terraced fan deposits have been identified on Mars [1-4], although their small sizes make them difficult to identify with the current data sets. The few fan dep...

BACKGROUND & OBJECTIVES Sensitivity of Ziehl-Neelsen (ZN) method is known to be low for liquefied sputum smears. Information on the ZN sensitivity for centrifuged deposit smears is not known. This study was carried out to determine the sensitivity of ZN method for acid fast bacilli (AFB) in centrifuged deposit smears and liquefied sputum smears made from sputum samples transported in cetyl-pyri...

qahr-abad fluorite deposit is located 58 km southeast of saqqez, in northwestern kordestan province and in northern end of sanandaj-sirjan zone. the factors such as change in physicochemical conditions of mineralization environment (ph and eh), variation in pressure and temperature, alteration, metamorphism, oxidation of organic matters, adsorption, activity and solubility of associated anions,...

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...

zafarabad iron deposit is located northwest of divandareh, in the northern margin of sanandaj-sirjan plutonic-metamorphic zone. the deposit is in lentoid to tubular shape, within a shear zone and occrrued in host rocks of calc-schist and limestone. magnetite with massive, cataclastic and replacement textures are the main phases, while pyrite and other sulfide minerals are found. major and trace...

It is important to conduct a comprehensive situational analysis when considering the introduction of a deposit insurance system or when planning to alter an existing deposit protection arrangement. In conducting such an analysis, the economic and institutional conditions and their effect on the alternatives available for a deposit insurance system must be considered. Among the conditions that s...
