Resumo -O Stock granítico Flores intrude gnaisses paleoproterozoicos, relacionados ao ComplexoCaicó, no Domínio Rio Piranha-Seridó, porção setentrional da Província Borborema, NE do Brasil. Este trabalho tem como objetivo a caracterização petrológica e geoquímica de seu monzogranitos. O Stock Flores compreende duas fácies petrográficas de monzogranitos equigranulares, leucocrá-ticos: i) monzogranitos rosados de granulação media; e ii) monzogranitos cinza rosados de granulação fina. Localmente ocorrem no Fácies Tipo II, enclaves máficos exibindo feições de coexistência de magmas (mixing e mingling), e schlieren elipsoidais, interpretados como estruturas formadas por convecção magmática. Biotita é o máfico principal; titanita, allanita, apatita, zircão e opacos ocorrem como minerais acessórios; fluorita, clorita e saussurita ocorrem como minerais tardios relacionados a fluídos em estágio subsolidus. As análises geoquímicas evidenciam a natureza evoluída do Stock e afinidade alcalina com teores de SiO 2 > 71,0%, e Na 2 O+K 2 O ~ 9,0%. Os diagramas discriminantes de ambiente tectônico demonstram a tipologia de granito Tipo-A. Tais dados são coerentes com a idade U-Pb 553±4 Ma encontrada para o Stock, o colocando dentro do contexto tardi-a pós-tectônico em relação à Orogênese Brasiliana/Pan-Africana na Província Borborema.

This work focused on the petrological and geochemical characterization of its monzogranites. The Flores Stock comprises equigranular, leucocratic monzogranites, which are divide in two petrografic facies: i) medium grained, pink monzogranites; and ii) fine grained, gray to pink monzogranites. Locally we can find in this type dioritic enclaves displaying magmas coexistence features (mixing and migling), and ellipsoidal schlieren formed by magmatic convection. Mineralogically, the Stock is constitued by biotite as its main mafic; titanite, allanite, apatite, zircon, opaque, and as late minerals, fluorite, chlorite and saussurite, these late ones are interpreted as related to fluids in subsolidus stage. The studied monzogranites show high SiO 2 contents (> 71% wt%) and alkaline affinity with Na 2 O + K 2 O ~ 9,0%. Tectonic discriminant diagrams of tectonic environment suggest a typology of A-type granite related to a post-collisional environment, which is corroborated by U-Pb zircon crystallization age of 553±4 Ma. Thus, the Flores Stock is interpreted as emplaced in a late to post-tectonic stage of the Brasiliana / Pan-African Orogeny in the Borborema Province

To investigate the integrity of the central nervous system of premature infants, there is a perform an assessment of primitive reflexes. Noteworthy is the evaluation of the Palmar and Plantar Gripping Reflexes soon after the baby's birth. This research aimed to perform a descriptive analysis of the clinical aspects after the birth of preterm infants born in a public hospital in a inland city's of Ceará, as well as to analyze an association between the Palmar and Plantar Gripping Reflexes with the analyzed aspects. It is a documentary, retrospective, correlational study with quantitative approach and exploratory objective. The sample consisted of 120 premature infants medical records between March 2017 and March 2018, in which information was collected in the Nursery File. The medical records analyzed revealed that there was a prevalence of premature limitrophe, as well as most changes related to color at birth, cyanosis, pulmonary and cardiac auscultation, difficulty breathing, abdomen, reactivity, tone, Moro reflex, suction reflex, palmar grip and Plantar grip and Apgar from the 1st and 5th minute. According to Pearson's Square (p <0.05), the Palmar and Plantar Gripping Reflexes show a significant association with most evaluated aspects. Thus, the study highlighted the importance of evaluating both reflexes soon after birth, demonstrating that their presence is related to the baby's respiratory and circulatory conditions, and, also, responsiveness and a tone.
