“…Según sus conclusiones, el ambiente de depositación de esta litología es sublitoral, somero, y la sedimentación se dio en un delta o fandelta. Lo propuesta anterior se ve reforzada en el área de estudio por el hecho de que es notable que la sedimentación fue cercana a la línea de costa, lo que se refleja en la granulometría de las volcarenitas, la abundancia de materia orgánica en las tobas, la presencia de brechas (gradación negativa), y coladas de lava intercaladas con los sedimentos, además de la presencia de peperitas (Soto y Alvarado, 2012).…”

“…El afloramiento en el tajo El Volcancito se considera clave para comprender las características de estas litologías, pues se observa una secuencia de basaltos, tobas y brechas por cizalle, donde es destacable la presencia de peperitas en el contacto vertical entre basaltos y tobas, obteniéndose un criterio de ambiente polaridad, pues marcan el piso de la colada. Es importante señalar que la presencia de peperitas en localidades cercanas ha sido también reportada por Soto y Alvarado (2012).…”

ABSTRACT:We present a geologic map of the Tapantí quadrangle, which is located in the central region of Costa Rica and belongs to the Central Costa Rica Deformed Belt (CCRDB). The CCRDB is a consequence of the interaction of the Cocos Ridge and the Western edge of the Panama microplate. The oldest rocks mapped in this work are Miocene in age and theyvbelongs to Pacacua, Peña Negra and Coris formations, than form the western edge of the Candelaria basin. Three igneous events were distinguished. First, the Miocene volcanic arc, which is represented by the rocks of La Cruz Formation and the clasts of Pacacua Formation. Another period of igneous activity was recorded in Grifo Alto and Doán formations and the Tapantí Intrusive, with an age range of 0.6-0.03 Ma. From a geochemical point of view is remarkable a change between 10 to 6 Ma, enrichment of K and Si and changes in U, Sr, Ba and La concentrations. This change corresponds with the Cocos Ridge arriving to the Middle America Trench and it is visible because the Pliocene magmatic arc, the Pliocene intrusive of Tapantí and the nowadays volcanic arc. The structural model suggests the existence of two deformation events, the first occurred during the period of time between Late Miocene and Pliocene and it formed the Folding Zone Orosi-Patarrá, and the second one corresponds to the establishment of CCRDB, from Pliocene to present, which is constituted by left lateral faults bearing ENE and right lateral faults bearing NW.

Since 1984, 50 issues of the Revista Geológica de América Central (RGAC) have been published, including a special unnumbered volume, with the 50 th issue published in 2014. The most common topics addressed among all articles include volcanic stratigraphy, petrology, geomorphology and volcanic monitoring. Volcanology-related themes represent 22% of all papers published in RGAC; over 30 years, there have been 86 such papers published, at a rate of 2.8 papers per year. Topics of volcanology are surpassed only by stratigraphy in general, which includes volcanic stratigraphy, radiochronology, and tephrostratigraphy. Since 1994, topics of volcanology have become increasingly common, as noted by several issues with 40 pages or more on related themes. Of the 51 issues of RGAC in 30 years, three were special volumes on Volcanology (No. 30, 2000; No. 43, 2010; and No. 48, 2013). Most published articles are geographically related to Costa Rica (88%), with very little work from the rest of the countries of Central America and none of Guatemala. While the community is working to encourage volcanological and geological studies in the rest of Central America, a number of constraints, particularly a lack of academic researchers in those countries, makes this a difficult task. The challenge for future generations is to maintain and pursue these goals at a national level.
