Scientists discover granite crystallizes at lower temperatures

Investigating the properties of granite has given researchers insight into how gold and other economically important ores are produced, the thermal properties of Earth’s crust, the state of magma in active volcanic regions, and how Earth’s continents formed. “The temperature of granite crystallization underpins our thinking about many of these phenomena,” researchers note in a new study in Nature. “But evidence is emerging that this temperature may not be well constrained,” added the study authors, who found that certain granites crystallize at temperatures as much as 200 degrees Celsius lower than previously thought.
