Mineralogical and geochemical evidence of magma mingling/mixing in the Sierra de las Cruces volcanic range, Mexican Volcanic Belt por Velasco Tapia, Fernando, Rodríguez Saavedra, Pedro, Márquez, A., Navarro de León, Ignacio, De Ignacio, Cristina, Marroquín Guerra, Sylvia Gabriela, Quintanilla Garza, Jesús, Rangel Alvarez, Oscar Mario

“…Both rock types are probably derived from partial melting of continental crust at different levels. The evidences of magma mixing and mingling include: (a) normal and sieved plagioclases in the same sample, rounded and embayed crystals, and armoured rims over the dissolved crystal surfaces; (b) subrounded, vesicular magmatic enclaves, ranging from a few millimeters to ~20 centimeters in size, with plagioclase + orthopyroxene + amphibole + quartz ± olivine ± Fe-Ti-oxides assemblage; (c) mineral chemistry evidence such as crystals with reaction rims or heterogeneous plagioclase compositions (inverse and oscillatory zoning or normally and inversely zoned crystals) in the same sample; and (d) elemental geochemical variations and trace-element ratio more akin to magma mixing and to some extent diffusion process. …”

Recursos alternativos para la identificación de Aspergillus spp. y la determinación de su potencialidad en la producción de aflatoxinas por Lozano Muñiz, Susana

“…The traditional identification process for these fungi is based on macro and micro morphological characteristics, but currently new immunological rapid methods and molecular techniques based on nucleotide sequence polymorphism from nuclear, ribosomal or mitochondrial DNA for studies at intra or inter specific level, have been developed. The objectives of this investigation were 1) identify A. flavus from other Aspergillus species that are important in health or industry, using amplification of intergenic ribosomal sequence and its electrophoretic analysis bye PAGE. 2) to subclone two intermediate enzymes before of the aflatoxin biosynthetic pathway on an E. coli system to obtain recombinant protein as a source for future studies on the potentiality of strains to produce aflatoxins. …”
