Sedimentary rocks can change into metamorphic rocks due to heat and pressure from the movements of the Earth. Those metamorphic rocks can be weathered, eroded, and the pieces transported away.

A recently published study in Nature has uncovered a previously underestimated contributor to the global carbon cycle—geological weathering of carbon-rich sedimentary rocks, reported EOS ...

Specifically, the researchers analyzed levels of the elements rhenium and osmium within the sedimentary rocks bracketing the glaciogenic deposits. Rhenium breaks down via radioactive decay ...

Ancient sedimentary organic matter (kerogen) represents the largest terrestrial organic carbon (OC) reservoir on earth and is vulnerable to remineralization upon exposure to earth’s atmosphere during ...

Weathering and cracking often occur along planes of weakness, a sedimentary layer, existing fracture, or a filled vein. You can also get unusual weathering patters based on the type of mineralogy ...
