Granite cooling rate

WebSep 8, 2024 · Two different crystal sizes within an igneous rock indicate that the cooling rate of the magma increased. While the magma was cooling slowly, larger crystals can form. However, if the magma starts to cool faster, only small crystals can form. WebJan 1, 2024 · This study focuses on high-speed heating followed by slow as well as rapid cooling of granite samples. Target temperatures of 400 °C and 800 °C were reached with heating rates of 200 °C/min, 300 °C/min and ISO 834 standard fire curve. Numerical simulations are used to investigate the temperature evolution inside the sample.
