Character and Origin of Climax-Type Molybdenum Deposits

TL;DR: The U.S. Geological Survey has a long and distinguished history in assessing the mineral resources of the public domain, and that role remains active today in programs designed to assess the mineral resource of the lands administered by the Bureau of Land Management and Forest Service, the Alaska Mineral Resource Assessment Program and the Conterminous United States Mineral Assessment Program.

TL;DR: In this article, the authors used the concept of a "chessboard" to classify mineral resources in the mixtum compositum of all geoscientific disciplines focused on one goal, finding new mineral depsosits and enhancing their exploitation.

TL;DR: The East Qinling-Dabie orogenic belt accommodates the largest Mo ore district in the world and contains 8.43 Mt of proven Mo metal reserves which accounts for 66% of the total proven Chinese Mo reserves as discussed by the authors.

TL;DR: A review of recent advances in this field, including experimental and theoretical investigations of halogen behaviour in volcanic and related magmatic systems, including halogen abundances in the mantle and magmas on Earth, the effects of halogens on phase equilibria and melt viscosities, their partitioning between melt and fluid phase(s) upon decompression, cooling and crystallisation of magmas in the Earth's crust; and their final atmospheric release as volcanic gases are discussed in this article.
