thorite

Because thorite is highly radioactive, specimens are often metamict.

He became known for describing several new minerals, such as Thorite, especially from the Langesundsfjorden district.

Also it was thought that the machinery wrecked by the thorite had served to propel and levitate the sphere.

Unlike thorite, huttonite is not affected by metamictization.

A variety of Thorite often called "Uranothorite", rich in Uranium, is highly radioactive.

It is dimorphous with tetragonal thorite, and isostructual with monazite.

Huttonite is dimorphic with thorite.

Much damage had been done by the thorite, and certain highly intricate mechanisms around the trap were hopelessly mined, to the extreme regret of the investigators.

It occurs in association with uraninite, thorite, pyrite, marcasite, roscoelite, clay minerals and amorphous organic matter.

Associated minerals include monazite, bastnasite, xenotime, thorite, zircon, apatite, rutile and hematite.

Other varieties of thorite include "orangite", an orange variety, and "calciothorite", an impure variety with trace amounts of calcium.

Industry and commerce: Bowers Group, BTAL, Thorite.

Coffinite is isostructural with the orthosilicates zircon (ZrSiO) and thorite (ThSiO).

Specimens of thorite generally come from igneous pegmatites and volcanic extrusive rocks, hydrothermal veins and contact metamorphic rocks.

A variety of thorite, often called "uranothorite", is particularly rich in uranium and has been a viable uranium ore at Bancroft in Ontario, Canada.

A comparison to the x-ray powder pattern of zircon (ZrSiO) and thorite (ThSiO) was the basis for this classification.

Thorium occurs in several minerals including thorite (ThSiO), thorianite (ThO + UO) and monazite.

On the island of Løvø, Norway, his son, Hans Morten Thrane Esmark, found the first specimens of a black mineral, thorite, from which the element thorium is derived.

Local industry includes Thorite - manufacturer of air compressors, air tools and pneumatic equipment, BTAL - a training centre, Bowers Group engineering works, a gas distribution depot, vehicle dismantlers and scrap yard.

It was beached on one of the South Shetland Islands, After vain attempts with milder explosives, the trap in the bottom was blasted open with thorite, a terriblc ncw compound of solidified gases, with which whole mountains had been shattered.

The material for the air foil was obtained from a Thorite's hang-glider and is made from a material called "Lyte Byte" which is specially made to capture and direct air currents and gives off a low-level of anti-gravity particles.
