👉 Ananthophyllitic is a type of mineralogy, which refers to a group of minerals that are similar in composition and structure but have different crystallographic structures. These minerals usually contain iron oxides (such as hematite) or calcium oxide (like feldspar), and they are typically found in igneous rocks such as granite, gneiss, and diorite. Ananthophyllites are often associated with metamorphic rocks because their mineral composition is altered by the transformation
