Slow cooling rock
WebbIn plutonic rocks that cooled slowly but reached T < 500 °C too fast, ordering remains incomplete (with Al concentrated in the T 1 o and T 1 m sites), developing a pseudo-monoclinic K-feldspar called orthoclase. Adularia is another partially ordered monoclinic feldspar (like orthoclase), which forms only in hydrothermal veins.

WebbAn example of slow cooling could the slow exhumation of a magma chamber through erosion of the overlying bedrock. In this scenario, the magma never erupts to the surface, it simply sits in the magma chamber and the overlying rock and soil are eroded away over the course of millions of years. WebbIf magma is trapped underground in an igneous intrusion, it cools slowly because it is insulated by the surrounding rock. Crystals have more time to grow to larger size. In smaller intrusions, such as sills and dykes, …

WebbWhen T0 is lower than ∼650 °C, low-diffusivity mineral-isotopic systems typically remain closed throughout their cooling history. As a consequence, the Ganguly and Tirone formulations are most useful for thermochronologic studies of igneous and granulite facies metamorphic rocks that cooled quickly from maximum temperatures in the 650–750 °C …
WebbTwo stages of cooling, i.e. slow cooling to grow a few large crystals, followed by rapid cooling to grow many smaller crystals could result in a porphyritic texture, a texture with two or more distinct sizes of grains. Single stage cooling can also produce a porphyritic texture.
