Benitoite (/ b ə ˈ n iː t oʊ aɪ t /) is a rare blue barium titanium cyclosilicate mineral, found in hydrothermally altered serpentinite. It forms in low temperature, high pressure environments typical of subduction zones at convergent plate boundaries. Benitoite fluoresces under short wave ultraviolet light, appearing bright blue to bluish ...

No land animals were present in Florida prior to the Miocene. The largest deposits of rock phosphate in the United States are found in Florida. [1] Most of this is in Bone Valley in central and west-central Florida. [2] Extended systems of underwater caves, sinkholes and springs are found throughout the state and supply most of the water used ...
Natrolite is one of the closely associated minerals with benitoite, a rare mineral with its type locality in San Benito County, California. Natrolite forms opaque white spherical inclusions within nodules of translucent green prehnite from Wave Hill, Northern Territory, Australia.
