Abstract

ABSTRACT

Cerro Chirripó, located in Chirripó National Park, Costa Rica, is the highest peak in the Central American isthmus. Though there already exist published geologic maps that encompass the study area, they lack the resolution and detail of the map produced by this study. Other materials produced by this study include a stratigraphic column, rock unit descriptions, and three cross-sectional transect profiles. These materials demonstrate the position and attitude of the rock units, their mechanism of emplacement, as well as their ages relative to one another. The aims of this study were to describe and map the observed rock units, characterize the spatial and temporal relations among said units, and elucidate current and past geologic processes that shape the tropical landscape of Chirripó National Park.
