WebFeb 16, 2007 · An important feature of the Hf isotope data is the spectrum of ϵHf values exhibited by zircons of the same rock (up to 10 ϵ units) ().Such variations within a single sample can only be reconciled by the operation of open-system processes that are capable of shifting the 176 Hf/ 177 Hf ratio of the melt from which the zircons precipitated. To … WebA number of processes that take place within a magma chamber can affect the types of rocks that form once magma cools and crystallizes. If the magma has a low viscosity— which is likely if the magma is mafic—the crystals that form early, such as olivine (Figure 7.11a), may slowly settle toward the bottom of the magma chamber (Figure 7.11b). in case of my death folderWebCombined Processes. As pointed out previously, if any of these process are possible, then a combination of the process could act to produce chemical change in magmas. Thus, although crystal fractionation seems to be the dominant process affecting magmatic differentiation, it may not be the only processes. in case of nazis break glass
