Mafic USA LLC announced plans in 2016 to employ over 100 people in Shelby. The company has ceased its operations there and a receivership auction is scheduled to sell "essentially all" of its assets.

In fact, it worked in temperatures up to 1,652 °F (900 °C), the temperature of erupting mafic volcano lava – the hottest type of lava on Earth.

He contends felsic rocks can form anytime mafic rocks sink deep within Earth—and not only along subduction zones. In fact, he argues this process can occur on a motionless plate.

The mafic or basaltic magma, which is only about 45 to 55 percent silicon dioxide, can be a very hot 1,832 to 2,192 degrees Fahrenheit. Molten rock that glows red is probably in the felsic ...

They're also cooler than mafic magmas. Rhyolite, an especially silica-rich type of lava, hits temperatures between only 1,200 degrees to 1,500 degrees Fahrenheit.

Researchers have conducted an integrated geochronological and geochemical study of mafic rocks in the Wutai Complex, North China Craton, revealing key insights into the Neoarchean ...

This is due to the low concentration of silica in the lava, and characteristic of basalt or mafic lava. Above you can see someone from the USGS sampling a lava flow from Kilauea Volcano.
