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 .
Archaeology is the study of human activity in the past, primarily through the recovery and analysis of the material culture and environmental data that they have left behind, which includes artifacts, architecture, biofacts (also known as eco-facts) and cultural landscapes (the archaeological record).

In addition, pabstite can be found in Rush Creek in California when benitoite contains small amounts of tin. It is commonly occurs in rocks that contain calcite, quartz, tremolite, witherite, phlogopite, diopside, minor amounts of forsterite and taramellite. Pabstite can also be found associated with galena, cassiterite and sphalerite. [7]
The site was discovered by Andrew Woodcock and Roy Shephard-Thorn in 1974. They recorded the geological sequence, in-situ artefacts and fossil mammal remains. Parts of the site complex were later excavated between 1982 and 1996 by a team led by Mark Roberts of the Institute of Archaeology, University College London. The site is situated in an ...
