Análisis microfacial, paleontológico y geoquímico en carbonatos de la Formación el Abra, Cerritos, San Luis Potosí, México por Ramos Hernández, Jennifer

“…The zone of Pseudolituonella reicheli of Middle - Late Cenomanian age was identified, nevertheless, the presence of Hippurites resectus, extends the stratigraphic range to the Turonian. A group of 13 representative samples was selected which were analyzed by ICPMS and X-ray diffraction to know the elemental composition of trace elements and rare earth and mineral phases, respectively. …”

Análisis estructural y estudio paleomagnético en el área potrero el colorado, porción occidental de la sierra la fragua, Coahuila, México por González Naranjo, Gildardo Alonso

“…The Potrero Colorado area is at the north part of the SMF, on the western part of La Fragua range, central part of Coahuila, Mexico. This area is a stratigraphic and structural window that allow us to see Jurassic rocks and faults not present in near parts over the SMF trace. …”

Arcos magmáticos del ordovícico y del carbonífero en el basamento de la Sierra Madre Oriental en el Anticlinorio Huizachal Peregrina. por Alemán Gallardo, Eduardo Alejandro

“…Aserradero Rhyolite results were inconclusive because of the limited population of zircon crystals in the rock, but the younger age (331.9 ± 5.2 Ma, Pensilvánico Medio) is congruent with its stratigraphic position in the Paleozoic Sedimentary Sequence, and radiometric ages previously reported on literature. …”

Estudio de los principales mecanismos de fosilización en rocas de la formación cupido, barremiano-aptiano del noreste de México. por Gómez Mancha, Yesica Edith

“…This work addresses fossilization and diagenetic processes in fossils derived from previously studied Cretaceous outcrops from which the exact stratigraphic location is well-known. The aim of this thesis was to identify, describe and interpret fossilization processes derived from Cupido Formation sequences in northeastern Mexico to add new palaeobiological information for paleonvironmental reconstruction. …”

Estudio geobiológico de la formación La Virgen y sus facies transicionales en los Potreros de Menchaca y La Virgen, Coahuila. por Gutiérrez Alejandro, Alejandra Guadalupe

“…ABSTRACT The Virgen Formation is a well-exposed stratigraphycal unit composed of alternating limestones and evaporites from the Lower Cretaceous that traditionally has been ascribed to a restricted lagoonal environment within a intracontinental basin. …”
