Group 2 The Alkaline Earth Metals

An alkaline earth metal, strontium is a soft silverwhite or yellowish metallic element that is highly reactive chemically. The metal turns yellow when exposed to air. Due to its extreme reactivity to air, this element occurs naturally only in compounds with other elements, as in the minerals strontianite and celestite.

The Geology of Rare Earth Elements

Rare Earth Ore Classification. Classification of ores related to alkaline rocks is also controversial. Table 2 presents a relatively simple classification that follows analogous categories for deposits related to nonalkaline igneous rocks. Some of the more unusual alkaline rocks that host, or are related to, REE ores are carbonatite and phoscorite, igneous rocks composed principally of ...
