Electron antineutrinos accompanying the β-decays of long-lived isotopes of uranium, thorium, and potassium in the earth carry information about the quantity and distribution of these geologically important, heat-producing isotopes. This letter discusses terrestrial antineutrino flux measurements at both a continental and an oceanic site. A combined analysis of both measurements provides informa...

The Lala copper area in Huili County, Sichuan Province, China, is favored by superior regional metallogenic geological conditions due to its location an extremely important copper–iron belt southwest and it has witnessed the formation of a series unique iron–copper deposits following superposition multiple tectonic events. In recent years, major mineral exploration breakthroughs have been achie...

Based on a pyrolitic compositional model, the lower mantle is mainly made of ferropericlase, aluminous silicate perovskite, and calcium perovskite. Silicate perovskite transforms into silicate post-perovskite structure just above the core-mantle region, the D" layer. The existence of iron in the lower-mantle minerals can affect a broad spectrum of the minerals’ physical and chemical properties....

The concept of petroleum reservoir geophysics is relatively new. In the past, the role of geophysics was largely confined to exploration and, to a lesser degree, the development of discoveries. As cost-efficiency has taken over as a driving force in the economics of the oil and gas industry and as major assets near abandonment, geophysics has increasingly been recognized as a tool for improving...
