Varieties of Trinitite

Many different types of Trinitite have been identified, with green being the most common. Black and red Trinitite contains iron from the tower structure. Red varieties also contain copper from the 'gadget' or the communication cables leading away from the test site. The presence of iron in Trinitite is attributed to the steel tower that held the bomb, as well as "Jumbo," the steel canister that housed the device.

The official environment in which Trinitite formed included sand, copper, iron/steel, and indigenous minerals present in the ground at the time of the atomic blast.
