Hydroand glaciovolcanism are processes that have taken place on both Earth and Mars. The amount of materials produced by these processes that are present in the martian surface layer is unknown, but may be substantial. We have used Mars rover analogue analysis techniques to examine altered tuff samples collected from multiple hydrovolcanic features, tuff rings and tuff cones, in the American we...

Quantitative petrography is a scientific and industrial direction of geology, which made huge progress due to developments inventions in information technology optics the last decade. This article introducing modern directions quantitative describes their current state art as well methodical approaches application. The research objects macropetrography are hand specimens, borehole cores polishe...

This work applies established analytical techniques of physical sciences to Irish brick in order to gather evidence of ceramic technologies, provenance and sources of raw materials. Petrographic microscopy, X-ray diffractometry and scanning electron microscopy with an energy dispersive Xray diffraction attachment were used to study the brick of Rathfarham Castle, Dublin, built c.1618, where cla...

Introduction: Impact melts resulting from craterproducing impacts on asteroids can be used to understand the collisional evolution of our solar system. Part of that analysis includes an assessment of the cooling rates of the impact melts and/or the locations where the melts are deposited. In this study, we examined LAP 04751 [1], which is an impact melt breccia that came from the H-chondrite pa...
