Geochemical patterns of schists from the Bushmanland Group: An artificial neural networks approach Lacassie Reyes, Juan Pablo; McClung, C. R.; Bailie, R. H.; Gutzmer, J.; Ruiz del Solar, Javier (ELSEVIER, 2006-12)The Mesoproterozoic Bushmanland Group is situated in the central region of the 1000 to 1200 Ma Namaqualand Metamorphic Complex (NMC). The NMC comprises a belt of highly deformed medium- to high-grade metamorphic rocks to ...

Achurra, L. E.; Lacassie Reyes, Juan Pablo; Le Roux, Jacobus; Marquardt, C.; Belmar Urbina, Mauricio; Ruiz del Solar, Javier; Ishman, S. E. (Elsevier, 2009)Manganese nodules recovered from two stratigraphic horizons of Tortonian–Messinian (late Miocene) age in the Bahía Inglesa Formation of north-central Chile were studied using XRD, SEM and geochemical analysis. The dominant ...
