Temperature-dependent susceptibility analyses and thermal demagnetization indicate that magnetite is cation substituted in cosmic spherules. The trend is consistent with a previous hypothesis that Transantarctic Mountain microtektites belong to the Australasian strewn field and that Indochina is the target region for the parent catastrophic impact.

In contrast to the textural variations, the bulk composition of the individual spherules is fairly homogeneous and broadly chondritic.

The infrared spectrum is similar to those of minerals of the pumpellyite group. Based on estimates of the projectile mass N 10 8 kg and numerical simulation of small-scale impacts from literature, we propose that the continental-scale distribution of the ablation interagomico was generated by the deceleration of a giant impact plume associated with a Tunguska-like impact over Antarctica.

We report the occurrence of microscopic inclusions of shocked quartz plus a Zr-phase and traces of Fe-oxide crystallites in Australasian microtektites recovered enlave deep-sea sediment cores within km of Indochina see [1] for details. Enter the email address you signed up with and we’ll email you a reset link.

The shocked quartz and the Zr phase are interpreted as relicts of the target rock. Resumption of the growth and progressive soil development, expressed by the carbon isotope record, occurred during the late part of MIS 8.

Pale-pink euhedral cobaltoan dolomite was associated with kolwezite [ Cu1.

The observed variations are consistent among the different proxies, and indicate that periods of reduced precipitation were marked by enhanced catchment erosion, probably due to a reduction in vegetation cover.

Pumpellyite- Al is transparent to translucent and exhibits an emerald-green to white colour, sometimes with bluish tinges. The lead atoms are nine-fold coordinated in form of tricapped trigonal prisms by chlorine and oxygen atoms. The main purpose of this work is enlacw make a first evaluation of the potential of the carbonate lacustrine sediment of the Mer-cure Basin Basilicata regionto preserve palaeoclimatic information during the Middle Pleistocene.

Tema N° 4 by Gunnar Arancibia Barrientos on Prezi

interatomicoo Full occupation of Ca at the A site is constantly found, with progressive Co incorporation at the B structural site leading to isotropic expansion of the B coordination octahedra and a corresponding anisotropic contraction of the A polyhedra, mainly achieved through the shortening of ”basal” polyhedral edges.

The major progressive shortening of apical bonds in Me2 octahedra, with consequent regularization of the Jahn-Teller distorted Cu octahedra, drives a progressive compaction of the malachite structure; it is the main factor accounting for volume contraction in cobaltoan malachites. The model has been confirmed through a least-squares refinement, carried out with observed reflections, to a final R of 0.
