  abstract = {{O}riginally developed for use in the petroleum industry, {R}ock-{E}val pyrolysis is a technique commonly applied to lake sediments to infer paleoenvironmental reconstructions. {T}he standard {R}ock-{E}val parameters provide information on the amount of total organic and inorganic carbon ({TOC} and {M}in{C}, respectively), and are usually interpreted as proxies for the source (aquatic or terrestrial) of the primary production of organic matter ({H}ydrogen {I}ndex vs {O}xygen {I}ndex). {A}lthough this method usually provides valuable evidence, the common presence of siderite in tropical lake sediments can alter the primary signal of the sedimentary organic matter ({SOM}). {I}ndeed, the {CO}2 and {CO} released by the pyrolysis of siderite are integral to the calculation of the {SOM}-related standard {R}ock-{E}val parameters. {I}n this study, we analyze sediments from a core collected in the {L}ake {B}arombi (southwest {C}ameroon) and describe the impact of siderite on standard {R}ock-{E}val parameters. {W}e propose a workflow that allows standard {R}ock-{E}val parameters to be corrected, based on the analysis of thermograms. {T}he proposed corrections provide siderite-effect-free parameters, accurately reflecting the changes in sedimentary organic matter composition.},
