The characteristics of the solar aureole were evaluated for several cases of a turbid atmosphere in the 3° ≤θ≤30° interval of scattering angles; for each case, the features of the aerosol were retrieved from the simulated aureole data. Computations were carried out with a recently set up radiative transfer code that uses the approximated delta-M method, corrected further for the 1st and 2nd sca...

To assess thermal and kinetic influences on atomic mobility mineral (neo)crystallization, clumped-isotope abundances of calcite dolomite were measured alongside cation ordering U–Pb dates, across metamorphic grade within the c. 35–30 Ma Alta stock contact aureole, Utah, USA. Average Δ47 values inside aureole reflect blocking temperature (300°C–350°C) during cooling from peak temperatures. Dolom...

The Bossòst dome is an E–W-trending elongated structural and metamorphic dome developed in Cambro-Ordovician metasedimentary rocks in the Variscan Axial Zone of the central Pyrenees. A steep fault separates a northern half-dome, cored by massif granite, from an E–W-trending doubly plunging antiform with granitic sills and dykes in the core to the south. The main foliation is a flat-lying S1/2 s...
