“…Siguiendo Révillon et al (2000), el punto caliente de "Galapagos" fue probablemente responsable del principal evento magmático de ~90 Ma, mientras que los episodios de 76 Ma y 55 Ma estarían relacionados con un adelgazamiento litosférico en el área central del Caribe (Mauffret et al, 2000). Por otro lado, aunque el CLIP comprende una amplia diversidad de composiciones de magmas basálticos, la gran mayoría de las lavas presentan una signatura empobrecida con valores de e Nd que gradúan entre +8,5 y +6,0, con un patrón normalizado respecto a la condrita plano o ligeramente enriquecido en las tierra raras ligeras (LREE; Sinton et al, 1998;Hauff et al, 2000;Lapierre et al, 2000;Révillon et al, 2000;Kerr, 2003;Thompson et al, 2004;Jolly et al, 2007;EscuderViruete et al, 2008EscuderViruete et al, , 2009EscuderViruete et al, y 2011.…”

“…Como puede observarse, los basaltos de la Fm Dumisseau de la Sierra de Bahoruco son de edad similar a los de la Fm Dumisseau de Haití (Sen et al, 1988) (Sinton et al, 1998) del área de Bonao, la cual incluye también intercalaciones de radiolaritas de edad Campaniense medio a Maastrichtiense (Montgomery y Pessagno, 1999). Estas edades son similares a la de las lavas máficas ricas en Nb de la Fm Sabana Grande del suroeste de Puerto Rico (Campaniense; Jolly et al, 2007), la edad K-Ar age de 75,0±1,5 Ma del sill dolerítico intrusivo en la secuencia superior de basaltos de la Fm Dumisseau en Haití (Sen et al, 1988), y la actividad magmática predominantemente Campaniense registrada en la Dorsal de Beata (80-75 Ma; Révillon et al, 2000), todas atribuidas al CLIP. Temporalmente, este magmatismo puede ser relacionado con la tercera fase de construcción del CLIP de Kerr et al (2002), así como con parte de los complejos oceánicos de la costa Pacífica de Costa Rica (Hauff et al, 2000;Hoernle et al, 2004;.…”

Escuder-Viruete, J., et al., 2017. El volcanismo basáltico de la Formación Dumisseau en la Sierra de Bahoruco, SO de la República Dominicana: registro del magmatismo de pluma mantélica de la Provincia Ígnea Caribeña. Boletín Geológico y Minero, 128 ( RESUMENLa Fm Dumisseau aflorante en la Sierra de Bahoruco ofrece la oportunidad de estudiar en tierra el magmatismo de pluma mantélica generador de la Provincia Ígnea Caribeña (CLIP) durante el Cretácico Superior. Consiste en una secuencia de unos 1.0-1.5 km de potencia compuesta principalmente por flujos basálticos y depósitos piroclásticos máficos, con depósitos sedimentarios volcanogénicos subordinados e intrusiones sin-volcánicas de sills y diques doleríticos. Todas las rocas volcánicas fueron emitidas o re-sedimentadas en condiciones marinas relativamente profundas, como atestiguan también las raras intercalaciones de chert y calizas pelágicas. En base al contenido en MgO, TiO2 y de elementos traza incompatibles, en la Fm Dumisseau se identifican tres grupos geoquímicos: toleitas pobres en Ti; basaltos ricos en Ti o transicionales; y basaltos alcalinos ricos en Ti y en LREE. La modelización geoquímica indica una procedencia a partir de fundidos generados e incorporados a diferentes profundidades en el manto, lo cual es consistente con los procesos que tienen lugar durante el ascenso de una pluma mantélica bajo la corteza oceánica. Dos edades 40 Ar/ 39Ar de roca total indican la extrusión de magmas al menos en el intervalo 92-74 Ma (límite Turoniense-Coniacense a Maastrichtiene), resultando coetáneos con la formación del CLIP. Como consecuencia, la Fm Dumisseau constituye un fragmento emergido del CLIP, con el que debe tener continuidad a través de la Dorsal de Beata. Estas rocas aparecen discordantes bajo las facies carbonatadas con algas rojas del Eoceno medio-superior, constituyendo el basamento volcánico cretácico de la Sierra de Bahoruco.

Zircon U–Pb dating and whole‐rock geochemistry of volcanic rocks in eastern Heilongjiang Province, NE China: Implications for the tectonic evolution of the Mudanjiang and Paleo‐Pacific oceans from the Jurassic to Cretaceous

The eastern Heilongjiang Province, NE China, is located in the eastern CAOB (Central Asian Orogenic Belt). Previous studies suggest that subduction of the Mudanjiang and Paleo‐Pacific oceans had been initiated in this area during the early Mesozoic. However, research on the Mesozoic volcanic rocks is insufficient, limiting our understanding of the relationship between magmatism and subduction process. To solve the problem, seven volcanic rocks in the Lesser Xing'an‐Zhangguangcai Range and the Jiamusi Block were collected for zircon U–Pb dating (SHRIMP) and whole‐rock geochemical analysis. Most samples from the Lesser Xing'an‐Zhangguangcai Range are Jurassic in age (189–178 Ma), including andesite, trachyandesite, trachydacite, and rhyolite. The andesitic to trachytic rocks were generated by magma mixing at an active continental margin, whereas the rhyolite is highly fractionated I‐type. All the samples from the Jiamusi Block and one basaltic andesite from the Lesser Xing'an Range are late Early Cretaceous in age (ca. 100 Ma) and were formed in a back‐arc extensional setting (roll‐back). Fractional crystallization was important in the generation of most Cretaceous rocks (basalt to trachydacite). However, magma mixing or crustal contamination was required to explain some andesites from the Jiamusi Block showing extremely low Cr, Ni, and Mg#. When integrated with the coeval blueschist‐facies metamorphism, the Early Jurassic volcanism indicates an active continental margin in the Lesser Xing'an‐Zhangguangcai Range due to the westward subduction of the Mudanjiang Ocean. After the closure of the Mudanjiang Ocean, two NE/NNE trending sinistral strike‐slip faults in NE China were triggered, accompanied by the slab roll‐back of the Paleo‐Pacific oceanic plate. The Jurassic continental arc and accretionary complexes in NE China were cut through by the two strike‐slip faults and bended to form small oroclines. At ca. 100 Ma, numerous accretionary complexes were accreted along the eastern margin of the CAOB, further forcing the retreat of trench and slab roll‐back. The late Early Cretaceous intra‐continental volcanism was generated in the Lesser Xing'an‐Zhangguangcai Range and Jiamusi Block during this roll‐back process.

In the Songpan-Garze fold belt of the northeastern Tibetan Plateau, an Indosinian lithospheric delamination model has been proposed, based on previous investigation of widespread granitoids. However, this model lacks comparable information from volcanism in the area. During the Indosinian delamination in the Songpan-Garze fold belt, whether partial melting of lithospheric mantle taken place is debated. This paper reports U-Pb zircon LA-ICP-MS ages, geochemical and Sr-Nd-Hf isotopic compositions from the Aba and Wasai calc-alkaline volcanic rocks in the central Songpan-Garze fold belt. Obtained magma crystallization ages are 210±3 Ma for the Aba andesite and 205±1 Ma for the Wasai andesite. These are consistent with magma crystallization ages of the late Indosinian granitoids in the Songpan-Garze fold belt that formed in a post-collisional tectonic setting. The Aba and Wasai andesites have distinct geochemical singnatures. The former has higher Al 2 O 3 , K 2 O, Rb but lower Na 2 O, Ba and Sr contents, suggesting differences in their magmatic evolution. The Aba andesites have I Sr values of 0.7070-0.7076 and ε Nd (t) values of −3.9 to −5.3, and the Wasai andesites have I Sr values of 0.7075-0.7077 and ε Nd (t) values of −3.6 to −3.9. Zircons show ε Hf (t) values of −3.7 to 0.3 for the Aba andesites and −2.7 to 5.5 for the Wasai andesites. Geochemical and Sr-Nd-Hf isotopic compositions indicate that fractional crystallization and crustal assimilation processes are not key roles for their magma evolution, implying that their chemical compositions are those of primary melts. We suggest that the magma of the Aba andesites originated predominantly from a crustal source, with a minor mantle-derived component. The source region of the magma was likely at the crust-mantle boundary. The magma of the Wasai andesites resulted from partial melting of lithospheric mantle, which was probably metasomatized by fluids so that it was amphibole bearing. The petrogenesis of the Aba and Wasai andesites provides an additional evidence for the lithospheric delamination in the the Songpan-Garze fold belt, indicating that this process invoked mantle asthenosphere upwelling and caused the partial melting of remaining lithospheric mantle. volcanism, U-Pb dating, geochemistry, petrogenesis, lithospheric delamination, Songpan-Garze fold belt Citation: Cai H M, Zhang H F, Xu W C, et al.
