Color in fossil insects, diamonds from the ancient ocean floor and modeling the world's largest rivers
Date:2/22/2013

riments show that the color generated by multilayer reflectors changes due to alteration of the refractive index and periodicity of the cuticle layers. Three-dimensional photonic crystals are equally resistant to degradation and thus their absence in fossil insects is not a function of limited preservation potential but implies that these color-producing nanostructures evolved recently. Structural colors alter directly to black above a threshold temperature in experiments, identifying burial temperature as the primary control on their preservation in fossils. Color-producing nanostructures can, however, survive in experimentally treated and fossil cuticles that now are black. An extensive cryptic record is thus available in fossil insects to illuminate the evolution of structural color.


Oxygen isotopes in the Azores islands: Crustal assimilation recorded in olivine
Felix S. Genske et al., GeoZentrum Nordbayern, Friedrich-Alexander-Universitt Erlangen-Nrnberg, Schlossgarten 5, 91054 Erlangen, Germany; and Australian Research Council Centre of Excellence for Core to Crust Fluid Systems/GEMOC, Macquarie University, Sydney NSW 2109, Australia. Posted online 20 Feb. 2013; http://dx.doi.org/10.1130/G33911.1.

The variability of the oxygen isotopic composition in magmatic systems is useful for the interpretation of the nature of ocean island basalts (OIB), especially since these volcanic rocks provide a clear view into the upper and possibly even lower mantle. The role of recycled material in Earth's mantle may therefore be constrained by geochemical studies of OIB. In detail, the source-sensitive isotope tracers have great potential to decipher individual contributions from subducted, recycled oceanic lithosphere and its components to the heterogeneous mantle. However, Felix S. Genske and colleagues show that recent assimilation of hydrothermally altered material dur
