About Magnet Cove
Magnet Cove in Hot Spring County, Arkansas, is a small but mineralogically extraordinary alkaline igneous complex — one of the world’s premier collector localities for brookite, schorlomite garnet, perovskite, and a unique TiO2-rich mineral suite.
Geology
The complex is a Late Cretaceous (~100 Ma) alkaline carbonatite-syenite ring intrusion in Paleozoic sediments. The unusual TiO2-Nb-rare-element chemistry produces a globally rare suite of minerals.
Notable Minerals
Brookite (lustrous black-amber tabular blades — world-class), rutile, schorlomite (jet-black Ti-bearing andradite garnet), perovskite, magnetite, vesuvianite, natrolite. Several species have Magnet Cove as their type or co-type locality.
Collector Notes
Magnet Cove brookite blades on quartz are the species’ iconic display form. Pair with Cavradi (Switzerland) and Pakistani brookite for a global polymorph display.
