Geochemical and field data collected from samples from ore deposits hosted in the Troodos ophiolite, Cyprus by Dr Andrew Martin during his PhD. File T1 contains sample names, locations and description and file T2 contains photographs and field observations for sample localities. File T3 contains portable x-ray fluorescence (XRF) data from powdered Troodos ophiolite samples. Files T4 - T8 contain sulphide trace element data from laser-ablation inductively-coupled-plasma mass-spectrometry (LA-ICP-MS) analysis of samples from various deposits in the Troodos ophiotlite. Files T9 and T10 contain bulk sample geochemistry from aqua regia digest and ICP-MS for deposits from the Troodos ophiolite. File T11 contains results from conventional ä34S analysis of sulfide minerals from Troodos deposits and file T12 contains x-ray diffraction analysis data from silica-rich deposits in the Troodos ophiolite. Data is used in papers available at https://doi.org/10.1016/j.oregeorev.2019.01.024, https://doi.org/10.1180/mgm.2018.81 and https://doi.org/10.1016/j.chemgeo.2019.119325 and in Dr Andrew Martin's PhD thesis, available at http://orca.cf.ac.uk/124346/.
