WebBasalts, through differentiation (fractioned crystallization), can generate other kinds of igneous rocks such as diorites and granites. They are weathered into sedimentary rocks … WebShock Metamorphism When extraterrestrial objects hit Earth, the result is a shock wave. Where the object hits, pressures and temperatures become very high in a fraction of a second. A “gentle” impact can hit with 40 GPa and raise temperatures up to 500 °C.

6.4 Types of Metamorphism and Where They Occur

WebThe low-grade metamorphism occurring at these relatively low pressures and temperatures can turn mafic igneous rocks in ocean crust into greenstone (Figure 6.27), a non-foliated metamorphic rock. Figure 6.27 Greenstone from the metamorphism of seafloor basalt that took place 2.7 billion years ago. The sample is from the Upper Peninsula of ... WebMar 2, 2024 · Because temperature decreases with distance from an intrusion, metamorphic effects also decrease with distance. Recall from Chapter 5 that minerals crystallize at specific temperatures. Metamorphic minerals that form at high temperatures occur closest to the intrusion, where it is hottest. northern a\u0026p
