Molybdenum (Mo) is a widely used trace metal for investigating redox conditions. However, unanswered questions remain that concentration and bulk isotopic analysis cannot specially answer. Improvements can be made by combining new geochemical techniques to traditional methods of Mo analysis. In this Element, we propose a refinement of Mo geochemistry within aquatic systems, ancient rocks, and modern sediments through molecular geochemistry (systematically combining concentration, isotope ratio, elemental mapping, and speciation analyses). Specifically, to intermediate sulfide concentrations...

This book focuses on the development of new theories and pedagogies of distance learning in the English class. It is a serious discussion of the development of effective means of conveying information, developing knowledge and perfecting skills. Through scholarly analyses it shows how distance learning calls instructors of English to different roles in the performance of their duties.
