Potassic igneous rocks were originally recognized in the late 19th century by Iddings (), who described some orthoclase-bearing basalts from the Yellowstone Park, Wyoming, and coined the term “shoshonite”.In the last century, petrologists generated many names for potassic igneous rocks which were either based on their mineralogy or, more …

It is most evident in kimberlites and to a lesser extent in alkali basalts, and reflects the generally high ratio of Fe 3+ to Fe 2+ in these rocks, as discussed further below. The increase in Ti is a secondary consequence of the increased tendency of Ti to partition into spinels with higher magnetite contents.
