Boulder, CO, USA The July issue of GEOLOGY presents studies on several aspects of temperature and climate change, a new river dataset examining whether the sedimentological record can help document floods, new data estimating motion of the Sagaing fault, active development of the NW British continental margin, how rivers react to earthquakes, and enigmatic volcanism of the Colorado Plateau. GSA TODAY looks at individual mineral grains as key to understanding the rise of the Andes.
Highlights on these and other topics are provided below.

Can we distinguish flood frequency and magnitude in the sedimentological record of rivers?

Geological deposits record the passage of time as an alternating set of sedimentary increments and gaps. Earth scientists have long debated whether these sediments are primarily the result of ordinary day-to-day processes that acted uniformly through time or are mostly extraordinary processes that acted spasmodically. The problem with answering this question is that it requires detailed quantitative data of how modern d
