"The Guacimal Pluton situated in the Cordillera de Tilar\u00E1n in the NW of Costa Rica forms an oval-shaped body with an exposed surface of 60\u201370 km2. The pluton intruded into basic volcanic rocks of the Aguacate Group (Miocene\u2013Pliocene) and is surrounded by a aureole of calc-silicate metasomatic rocks. The pluton is mainly formed by monzogranites to granodiorites, which strongly prevail over more basic types. The pluton was emplaced at depth of c. 3 km, crystallized at temperature of c. 760\u2013800 \u00B0C under a relatively high oxygen fugacity (1.6\u20132.1 log units above the NNO buffer) and increased activities of volatiles (H2O, F) upon cooling. The prevailing, felsic rocks of the Guacimal Pluton are high-K calc-alkaline. Laser ablation ICP-MS dating of zircons from two granite samples yielded statistically identical U\u2013Pb ages of 6.3 \u00B1 0.5 and 6.0 \u00B1 0.4 Ma, respectively. The Sr\u2013Nd isotopic compositions are rather primitive (87Sr/86Sr6 = 0.70380\u20130.70413, e6Nd ~ +7.3 to +7.9)." . . . "10.3190/jgeosci.087" . "Huapaya, Sofia" . "209030" . . . "4"^^ .
