Regolith production and chemical weathering of granitic rocks in central Chile
(Elsevier, 2016)
We have evaluated the long-term chemical and physical weathering mass balance of an anomalously thick saprolite profile (>30 in thickness) developed in granitic rocks near Curacavi, Coastal Range of central Chile. The ...
Colluvial deposits as a possible weathering reservoir in uplifting mountains
(European Geosciences Union, 2018)
The role of mountain uplift in the evolution of the global climate over geological times is controversial. At the heart of this debate is the capacity of rapid denudation to drive silicate weathering, which consumes CO2. ...
Weather regimes linked to daily precipitation anomalies in northern Chile
(Elsevier, 2020)
Northern Chile is one of the most arid regions in the world, with precipitation mainly occurring during austral summer, between December and April. The aim of this study is to classify the main weather regimes derived from ...
Organic acids and high soil CO2 drive intense chemical weathering of Hawaiian basalts: insights from reactive transport models
(Elsevier, 2019)
We have investigated how biota contributes to rapid chemical weathering of Hawaiian basalts using a reactive transport
model and chemical data from a soil chronosequence. These Hawaiian soils have developed under a tropical ...
Topoclimatic Zoning and Representative Areas as Determined by an AutomaticWeather Station (AWS) Network in the Atacama Region, Chile
(MDPI, 2020)
Climate information is crucial to the management and profitability of key development
sectors involving agriculture, hydrologic resources, natural hazards, and energy. Climate knowledge,
real-time weather information, ...
High impact weather events in the Andes
(Frontiers Media, 2020)
Owing to the extraordinary latitudinal extent, a strong orographic variability with very high mountain tops, and the presence of deep valleys and steep slopes, the Andes and the population of the region are highly prone ...
Platinum-group element and gold enrichment in soils monitored by chromium stable isotopes during weathering of ultramafic rocks
(Elsevier B.V., 2018)
Weathering of ultramafic rocks can lead to the formation of soil profiles with high contents of Fe, Ni, Co, platinum-group elements (PGE) and gold. Traditionally, these metal-rich soils are known as “laterites” and are ...
How Do Surficial Lithic Assemblages Weather in Arid Environments? A Case Study from the Atacama Desert, Northern Chile
(Wiley, 2015)
Archaeological sites composed only of surficial lithics are widespread in arid environments. Numerical dating of such sites is challenging, however, and even establishing a relative chronology can be daunting. One potentially ...
Contribution of Anthropogenic Factors and Climate Variables to Human Cystic Echinococcosis Mortality in Chile (2001-2011)
(Mary Ann Liebert, 2020)
Here we assess the effect of weather and anthropogenic environmental variables, particularly urbanization, on cystic echinococcosis mortality in Chile from 2001 to 2011 using a nonparametric regression model, multivariate ...
Winter weather regimes over the Mediterranean region: their role for the regional climate and projected changes in the twenty-first century
(Springer, 2013)
The winter time weather variability over the
Mediterranean is studied in relation to the prevailing
weather regimes (WRs) over the region. Using daily geopotential
heights at 700 hPa from the ECMWF ERA40
Reanalysis ...
