Thermogravimetric Analysis profiles as xy datasets of limonites from Acoje (Philippines), Caldag (Turkey), Piaui (Brazil) and Shevchenko (Kazakhstan) laterite deposits. The data were acquired during the NERC SoS Minerals CoG3 project between 2015 and 2018 using a TA Instruments Thermogravimetric Analyzer (TGA) instrument at the Natural History Museum, London, UK. Powdered samples were loaded into the TGA and heated at 10 degrees C per minute up to 800 degrees C under a flowing N2 atmosphere. Information regarding the type and proportion of hydrous or volatile rich mineral phases can be obtained from the decomposition profile. This may be useful within the mining sector, resource assessment, processing or prospecting, geo- or material scientists and processing engineers / metallurgists. The data were acquired in the Earth Sciences Department, Natural History Museum by the NHM CoG3 team. NERC grant: CoG3: The geology, geometallurgy and geomicrobiology of cobalt resources leading to new product streams

This dataset contains the raw data from Thermogravimetric Analaysis (TGA) of samples from 3 different field locations - Warton, Derwent Howe, Harrington. The data was collected in 2022-2023. The data was collected for the purpose of identifying the volume of different carbon-bearing materials (specifically carbonate minerals) in the collected samples. The data was collected by John MacDonald and Robin Hilderman (University of Glasgow) who retain the original data.
