Disturbing former farmlands can rouse old pesticides, says Dartmouth research
...these toxic metals do not remain in their original mineral
form. Instead, they are now part of the fine silt and organic matter in the soil, which is most susceptible to erosion. "We learned that disturbing this land, for example tilling and replanting, mobilizes the arsenic and lead," says Renshaw. "The re...

UC Riverside researchers identify clay as major contributor to oxygen that enabled early animal life
... researchers found evidence of an increase in clay mineral
deposition in the oceans during a 200 million year period that fell between 1.1 to 0.54 billion years ago a stretch of time known as the late Precambrian when oxygen suddenly increased in the Earth's atmosphere. The increases in clay formation and o...
