[Tectonos] Neodymium depleted mantle model age map of Australia

[Roberto D. Martino]

Estimados colegas:

"(*)Geoscience Australia has released the first isotopic maps of the Australian continent. The maps are based on the Sm-Nd isotopic signature of felsic igneous rocks, providing a proxy that allows regional-scale mapping of the crust and crustal growth. The record (2013/44), with accompanying downloadable isotopic datasets and images, details the theory behind the methodology, the advantages and disadvantages of the technique, as well as comparing results of the isotopic map with current knowledge of Australian crustal blocks and tectonics. It also investigates the potential of the isotopic map for identifying metallogenic regions, with examples regarding nickel, VHMS, IOCG and porphyry Cu-Au mineral systems. The record can be downloaded from Geoscience Australia websitehttp://www.ga.gov.au/products/servlet/controller?event=FILE_SELECTION&catno=77772"

Muy interesante e ilustrativo. 

Uno ve que en otros lados andan en una 4x4 y nosotros renegando con el "fitito" que gasta aceite y la segunda que no entra bien, a pesar del doble embrague.

Un cordial saludo a todos.
