Early studies of the thermal state of the Cocos plate subducting beneath the northern Costa Rica margin identified two adjacent areas of higher (>100 mW/m 2) and lower (<30 mW/m 2) heat flow. Measurements on crust formed at the Cocos-Nazca spreading center (CNS) were generally in agreement with later predictions from conductive lithospheric cooling models, whereas measurements on East Pacific Rise (EPR) crust were commonly lower by ~70%. However, the sparse distribution of early data precluded… CONTINUE READING
