Using eleven new control points, we recalibrated the initial rapid growth phase of the previously established Rhizocarpon subgenus Rhizocarpon growth curve. This curve was then used to estimate the age of "Little Ice Age" moraines. The time of deposition of the most prominent and numerous terminal and lateral moraines on the Pacific-facing side of the Cordillera Blanca (between AD 1590 and AD 1720) corresponds to the coldest and wettest phase in the tropical Andes as revealed by ice-core data. Less prominent advances occurred between AD 1780 and 1880. specialized "Little Ice Age" moraines cordillera blanca lichenometry 021 064 59 1-4 225-235 2007 0921-8181 https://www.documentation.ird.fr/hor/fdi:010040925 10.1016/j.gloplacha.2006.11.016 0921-8181 [F B010040925] https://www.documentation.ird.fr/hor/fdi:010040925 https://www.documentation.ird.fr/intranet/publi/2008/01/010040925.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-02-22 2017-08-23 fdi:010040925 fre
