Description:
The Periodic Table of the elements is essential for understanding the geochemical behavior of trace elements. Elements in yellow squares are major elements because their abundances in igneous rocks are typically greater than 0.1 wt.%. Note that the majority of elements (pink squares) have abundance less than 0.1 wt.%; they are trace elements. Background photo (from USGS) is a basaltic eruption at Kilauea Volcano, Hawaii.
