Data from the COSC-2 borehole in central Sweden (63.3124° N, 13.5259° E) at an elevation of 320 m with a depth of 2276 m from the surface. Data encompasses mineral analysis, including isotopic, age of calcites using U-Pb, and clumped isotopic analysis of calcites. Fluid analysis include hydrogeochemistry, stable isotopes of water, gas composition and gas isotopic composition of hydrocarbons.

Data från COSC-2 borrhålet i centrala Sverige (63,3124° N, 13,5259° E) på en höjd av 320 m med ett djup på 2276 m från markytan. Data omfattar mineralanalys, inklusive isotoper, ålder på kalkiter med U-Pb och sammansatt isotopanalyser av kalkiter. Vätskeanalys inkluderar hydrogeokemi, stabila isotoper av vatten, gaskomposition och gasisotopsammansättning av kolväten. 2022-08-29 2022-09-03 Sweden Sverige Numeric Text Data was collected in the field and from drill cores. Fluid samples (groundwater and gas) were collected along different depths of the COSC-borehole utilizing a Leutert Positive Displacement Sampler (PDS). At 975 m depth the sampling was later repeated using packers and a pressurized in situ sampling device (PAKO). Pump samples were also taken from 40 m depth and spontaneously separated gas collected at the wellhead. Mineral samples were collected from open or sealed fractures.Data was collected in the field and from drill cores.
