The rover Opportunity has investigated the rim of Endeavour Crater, a large ancient impact crater on Mars. Basaltic breccias produced by the impact form the rim deposits, with stratigraphy similar to that observed at similar-sized craters on Earth. Highly localized zinc enrichments in some breccia materials suggest hydrothermal alteration of rim deposits. Gypsum-rich veins cut sedimentary rocks...

A. We introduce some free boundary problems which describe the evolution of calcium carbonate stones under the attack of atmospheric SO2, taking into account both swelling of the external gypsum layer and the influence of humidity. Different behaviors are described according to the relative humidity of the environment, and in all cases reliable explicit quasi steady approximations are in...

The study area (Kalateh-No) is located in NW of Gonabad city in Khorasan Razavi Province. This area is located in geotectonic Lut Block zone. The rock types are mainly of volcanic and subvolcanics. The most important alteration zones are silisification, propylitic, argillic, serisitic and quartz-serisit-pyrite. The mineralizations have formed by intrusion of hydrothermal fluids of monzodiorite ...

Military forces operating in urban environments are facing numerous challenges. One of them consists in being able to identify buildings material to support missions involving tactical breach or blast damage prediction. This paper reports on a method that combines both LIDAR and through-wall radar imagery to provide detailed information about a building front wall features and its construction ...
