P–T path that best reproduces observed garnet zon-ing can be difficult. In this study, the problem of finding the P–T path that most closely reproduces garnet zoning in a natu-ral sample is addressed with an automated method that finds a best-fit between observed and modelled garnet compositions, while iteratively accounting for

Towards a Creationist Explanation of Regional Metamorphism ...

This leads to a proposal for a creationist explanation of regional metamorphism. Two major events within the creationist framework of earth history are capable of producing regionally metamorphosed terrains—the tectonism, catastrophic erosion and sedimentation during the formation of dry land on Day Three of Creation Week, and the ...

Kyanite Meanings and Uses | Crystal Vaults

Kyanite's energy is unlimited in application, making it an excellent stone for metaphysical purposes, and it may be used for cleansing and clearing other crystals. [Melody, 363][Eason, 225] Kyanite is an aluminum silicate mineral, often occurring as long, striated bladed crystals that may be transparent or translucent with a pearly sheen.

Kyanite - Wikipedia

Kyanite is a member of the aluminosilicate series, which also includes the polymorph andalusite and the polymorph sillimanite. Kyanite is strongly anisotropic, in that its hardness varies depending on its crystallographic direction. In kyanite, this anisotropism can be considered an identifying characteristic.
