##tihuan2##Spodumene formation is limited to the inner units of lithium rich pegmatites, namely because it needs very high concentration of lithium. Spodumene can form several generations within one pegmatite, both magmatic and hydrothermal. Common spodumene is pale colored and forms crystals inside the blocky unit.
