Scientist unlocking secrets from Sudbury's black rocks
A Sudbury scientist is scratching the surface of the black rock that makes up much of the city's landscape and he's making some new discoveries.
Michael Schindler, who works out of Laurentian University, said he has been studying the many little particles that originated from the nickel smelting process and stuck to the black rock coating.
The coating is composed of something called silica — a material that has the ability to trap particles, especially after the rain. Using a high-resolution magnifier, he has been able to see some unique substances.
"There [are some] very small particles that have not been detected before," he said.
