How is biotite granite formed
Web28 feb. 2024 · Apatite Sr-Nd and zircon Hf-O isotopes are broadly used to trace magma sources and constrain magma evolution processes, further improving our understanding of the origin of granitoids. We present zircon U-Pb ages, whole-rock major and trace elements, and whole-rock Sr-Nd-Hf, zircon Hf-O, and apatite Sr-Nd isotopic data for the coarse … WebBeing an igneous rock, granite is formed from the solidification and cooling of magma. ... Quartz content can range from 10-60%, while the feldspar content typically ranges from 65-95%, and biotite content is around 10-15% in most granite. The exact chemical composition will vary greatly but there is an average chemical composition for granite.
