  abstract = {{W}e present a new 52 m composite record ({COL}17c) composed of five sedimentary sequences retrieved from the {C}olonia basin ({S}outheastern {B}razil). {T}he {COL}17c record is composed of two main sub-units deposited under different regimes: a peatland above similar to 14 m and lacustrine sediments below. {S}edimentary description and core scanning ({MSCL} and {XRF}) are first used to align individual cores in order to produce a nearly continuous composite record. {W}e then established an original chronological framework based on radiocarbon, paleomagnetic, optically stimulated luminescence ({OSL}), post-infrared infrared stimulated luminescence at elevated temperature (p{IRIR}(290 degrees {C})) and authigenic {B}e-10/{B}e-9 dating. {W}e describe the protocols used for each technique and discuss the positive and negative results, as well as their implications for proxy interpretation. {I}n spite of negative results of some techniques, mainly due to the absence of adequate sample material, the multi-proxy approach used is essential to maximize the chances of obtaining a satisfactory age model for this unique continental sedimentary sequence. {A}ll valid chronological proxies, comprising three {AMS} {C}-14 ages, one p{IRIR}(290 degrees {C}) age, two paleomagnetic constraints and eight authigenic {B}e-10/{B}e-9 datum, are integrated within a {B}ayesian age-depth modeling to produce a 1.5 +/- 0.1 {M}a chronology for the whole {COL}17c sequence. {T}his age model represents the first long-term chronological estimate of sediments deposition in the {C}olonia basin. {T}he record allows to refine the age of the {C}olonia basin formation between 5.3 and 11.2 {M}a, much older than previously estimated from short sedimentary cores.},
