@article{fdi:010042947, title = {{A} fifty-year climatic signal in three {H}olocene stalagmite records from {M}ato {G}rosso, {B}razil}, author = {{S}oubi{\`e}s, {F}ran{\c{c}}ois and {S}eidel, {A}. and {M}angin, {A}. and {G}enty, {D}. and {R}onchail, {J}. and {P}lagnes, {V}. and {H}irooka, {S}. and {S}antos, {R}.}, editor = {}, language = {{ENG}}, abstract = {{T}hree stalagmites were collected in the "{P}erolas" cave, 150 km {NW} of {C}uiaba, {M}ato {G}rosso, {B}razil, in order to reconstruct the climate history of the surrounding region. {T}hese stalagmites were similarly formed by stacking of thousands of calcitic pairs of laminae. {M}icrophotographs of polished thin sections were used to count the laminae pairs and measure their width. {A} reasonable fit was found between the counting results and {U}/{T}h and {C}-14 geochronological data, proving that these pairs are annually deposited; and correlations were also found between the annual growth rate of the stalagmites and the annual water excess in the {P}erolas region, proving that the former parameter could be used as a climatic proxy. {T}hree files of climatic proxy data covering 256 years were thus obtained and statistically treated to restore the historical fluctuations of the climate. {A}part from well-documented periodicities, a still poorly known but very strong half-century climatic oscillation appeared in the results.
