Titanium in the Old Hickory Heavy Mineral Sand Deposit
Sediments were churned by waves at the shoreline. Light minerals, such as sand-sized crystals of quartz (silicon dioxide), were carried further away from heavy titanium and zircon crystals. During times of marine transgression in the Pliocene Epoch, titanium was concentrated in heavy mineral sand deposits on the beaches. 1

Heavy Mineral Analysis
Heavy minerals. Most sands are composed for 99% of light minerals such as quartz (s.g. 2.65) and feldspar (s.g. 2.54 – 2.76). Therefore, sands are mainly distinguished on the basis of their variable heavy mineral content. Heavy minerals are considered to be those minerals with a specific density greater than 2.8.
