In Nicaragua, this age is less constrained but is likely within the range 600 ka to 330 ka. In Costa Rica, the new geochronologic data significantly improve estimates of the volumes of the volcanoes because they define the contact between the active volcanoes and the previous volcanic front, which is substantially older (2.2 to 1.0 Ma). In addition, the contrast in extrusive volcanic flux between western Nicaragua (1.3 \u00d7 10<jats:sup>10<\/jats:sup> kg\/m\/Myr) and central Costa Rica (2.4 \u00d7 10<jats:sup>10<\/jats:sup> kg\/m\/Myr) is greatly reduced from previous estimates and now within the range of error estimates. We estimate the subducted component of flux for Cs, Rb, Ba, Th, U, K, La, Pb, and Sr by subtracting estimated mantle\u2010derived contributions from the total element flux. An incompatible element\u2010rich OIB source for the Cordillera Central segment in Costa Rica makes the subducted element flux there highly sensitive to small changes in the modeled mantle\u2010derived contribution. For the other three segments studied, the estimated errors in concentrations of highly enriched, subduction\u2010derived elements (Cs, Ba, K, and Pb) are less than 26%. Averaged over the time of the current episode of volcanism, the subduction\u2010derived fluxes of Cs, Ba, K, Pb, and Sr are not significantly different among the four segments of the Central American volcanic front in Nicaragua and Costa Rica. The subduction\u2010derived fluxes of Th and La appear to increase to the SE across Nicaragua and Costa Rica, but the estimated errors in their subduction\u2010derived concentrations are very high, making this variation questionable. The lack of change in the fluxes of Cs, Ba, K, Pb, and Sr argues that the well\u2010defined regional variation in Ba\/La is the result of changes in the mode or mechanics of fluid delivery into the mantle wedge, not the total amounts of fluids released from the slab. Concentrated or focused fluids in Nicaragua lead to high degrees of melting. Diffuse fluids in Costa Rica cause lower degrees of melting.<\/jats:p>","DOI":"10.1029\/2006gc001396","type":"journal-article","created":{"date-parts":[[2007,6,1]],"date-time":"2007-06-01T21:12:41Z","timestamp":1180732361000},"source":"Crossref","is-referenced-by-count":96,"title":["Element fluxes from the volcanic front of Nicaragua and Costa Rica"],"prefix":"10.1029","volume":"8","author":[{"given":"Michael J.","family":"Carr","sequence":"first","affiliation":[{"name":"Department of Geological Sciences Rutgers University  610 Taylor Road, Piscataway New Jersey 08854\u20108066 USA"}]},{"given":"Ian","family":"Saginor","sequence":"additional","affiliation":[{"name":"Department of Geological Sciences Rutgers University  610 Taylor Road, Piscataway New Jersey 08854\u20108066 USA"}]},{"given":"Guillermo E.","family":"Alvarado","sequence":"additional","affiliation":[{"name":"Seismology and Volcanology Instituto Costarricense de Electricidad  Apartado 10032\u20101000 Costa Rica"}]},{"given":"Louise L.","family":"Bolge","sequence":"additional","affiliation":[{"name":"Department of Geological Sciences Rutgers University  610 Taylor Road, Piscataway New Jersey 08854\u20108066 USA"}]},{"given":"Fara N.","family":"Lindsay","sequence":"additional","affiliation":[{"name":"Department of Geological Sciences Rutgers University  610 Taylor Road, Piscataway New Jersey 08854\u20108066 USA"}]},{"given":"Kathy","family":"Milidakis","sequence":"additional","affiliation":[{"name":"Department of Geological Sciences Rutgers University  610 Taylor Road, Piscataway New Jersey 08854\u20108066 USA"}]},{"given":"Brent D.","family":"Turrin","sequence":"additional","affiliation":[{"name":"Department of Geological Sciences Rutgers University  610 Taylor Road, Piscataway New Jersey 08854\u20108066 USA"}]},{"given":"Mark D.","family":"Feigenson","sequence":"additional","affiliation":[{"name":"Department of Geological Sciences Rutgers University  610 Taylor Road, Piscataway New Jersey 08854\u20108066 USA"}]},{"suffix":"III","given":"Carl C.","family":"Swisher","sequence":"additional","affiliation":[{"name":"Department of Geological Sciences Rutgers University  610 Taylor Road, Piscataway New Jersey 08854\u20108066 USA"}]}],"member":"13","published-online":{"date-parts":[[2007,6,2]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1029\/2002GL015649"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00302004"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0895-9811(92)90005-J"},{"key":"e_1_2_7_5_1","series-title":"Spec.
