Persistent pressure and high temperature make the resin appear like orange gems. Young or copal amber is formed due to the polymerization of molecules. Over time, heat and high pressures drive the terpenes out thereby completing the transformation of the amber. Usually, only two forms of resin m...
How is a magma chamber formed? How do crystalline sedimentary rocks form? What forms when magma cools? How is metamorphic rock dependent on minerals? How do coarse grained igneous rocks form? What process causes igneous rock to transform into metamorphic rock?
This rock type is formed by the solidification of molten magma either at the surface as volcanic lava, or within the Earth’s crust. Most of the common gemstones are formed in this rock type. Igneous rocks are divided into two (2) major types: Intrusive igneous rocks: Igneous rocks which ...
