The major, trace element, and Li isotopic compositions of granodiorite and metapelites from the Onawa pluton and surrounding contact aureole have beenmeasured to document the behavior of Li and its isotopes during progressive metamorphic dehydration. Major and trace element concentrations inmetapelites of the contact aureole change little, while loss on ignition (LOI) decreases with increasing ...

Intrusions of magma induce thermal aureoles in the country rock. Analytical solutions predict that the thickness of an aureole is proportional to the thickness of the intrusion. However, in the field, thermal aureoles are often significantly thinner or wider than predicted by simple thermal models. Numerical models show that thermal aureoles are wider if the heat transfer in the magma is faster...

The forward scattering of sunlight by atmospheric aerosols causes a bright glow to appear around the Sun. This phenomenon, the simplest manifestation of the solar corona, is called the solar aureole. Simple methods can be used to photograph the solar aureole with conventional and digital cameras. Aureole images permit both a visually qualitative and an analytically quantitative comparison of au...

Point sources in the atmosphere are surrounded by aureole because of atmospheric scattering. The properties of the time-dependent aureole radiance are calculated by use of a Monte Carlo approach and an iterative method. Since the aureole is particularly important in the ultraviolet, which is the region the Ultra-High-Energy (UHE) cosmic ray experiment using the air fluorescence technique like F...

Introduction: Large basaltic volcanoes, such as Olympus Mons on Mars, and the Hawaiian volcanoes on Earth, are thought to be subject to large scale slope failure and flank collapse, which scatter landslide and avalanche debris (a.k.a., aureole deposits) about the base of the edifice [1], [2], [3], [4], [5]. Volcano growth may also be accompanied by gravitational relaxation of the edifice, refer...
