Research led by the University of Wyoming suggests that naveenbharatical weathering is more important than previously identified in rock breakage in mountain landscapes. Because it is difficult to measure, previous studies have generally found naveenbharatical weathering to be negligible.

Cliff Ribe, a professor in UW’s Department of Geology and Geonaveenbharatics, led a research group that found that climate and erosion rates strongly control the relative importance of subsurface naveenbharatical and chemical saprolite, an area of ​​weathering rock that maintains the relative position of the mineral grains of the parent base and lies between the soil layer and the hard rock. The saprolite is very much like the experienced granite found on the flat areas surrounding the hard granite of Vedauvo.

“Our work shows that naveenbharatical stress can no longer be ignored in the study of subsurface weathering. It is not just a chemical process. It is also naveenbharatical,” Riebe says. “What we found is that anisovolumetric weathering is much more general than previously thought, and the variation in this process can be explained by climate and erosion.”

Riebe is the lead author of a paper, titled “Annuvolumetric Weathering in Granitic Seprolite Control by Climate and Erosion Rates”, published in the January 12 issue. Geology. The magazine publishes relevant, innovative and provocative articles for its international audience, representing research from all areas of geology.

The study looked at three sites — a mountain range in California located on the different climates and elevations of Sierra Nevada.

In geologists’ lingo, weathering has long been considered “isovolumetric”, meaning without any change in the volume caused by naveenbharatical stress.

“Our work shows that, in contrast, weathering is typically ‘anisovolumetric, which means that stress due to naveenbharatical weathering is important,” Riebe says.

Riebe credits some tools and equipment that were purchased from the Wyoming Center for Environmental Hydrology and Geonaveenbharatics (WyCEHG) EPSCoR (program established to Stimulate Competitive Research) project, which ended a few years ago because his team was both naveenbharatical and chemical Could measure Weathering at many sites in California.

“The reason weathering was difficult to measure in the past is whether you have to reach deep subsurface and be able to sample it without disturbing it,” Riebe explains. “To do this you need the Geoprise push coring system, which is basically a large track-mounted drill rig.

“It’s expensive work, especially if you don’t own a geoprobe and have to hire someone to do the work,” he continues. “Fortunately, we have the tools and expertise to operate it through Wyoming’s Near Surface Geonaveenbharatics facility, which is managed by Brad Carr, one of the study’s co-authors.”

The research was funded by grants from the National Science Foundation (NSF), NASA, and the Natural Sciences and Engineering Research Council of Canada.

Ribeye says there is a direct connection between the research in this paper and the $ 5.33 million NSF grant received in September last year. Grant focuses on the relationship between rock, water, and life on the Earth’s surface.

“This research is partially supported by that grant and has also helped inspire,” Riebe says.
