Data for: Natural mineralized fractures from the Montney-Doig Formations (Western Canada Sedimentary Basin): controlling factors and implications for unconventional exploration

Table S1a. Details on investigated samples from well core 16-17, including sample name, depth, sequence of provenance, depositional environment, number of fractures, their orientation and kinematic aperture, texture of the sealing calcites and their O-C-Sr isotope composition. In some samples, O-C isotope analysis were performed for different veins or for different calcite textures occurring in the same vein. Table S1b. Same as in Table S1a for the samples from well core 12-36. Table S2a. Details on samples from well core 16-17, including sample name, depth, sequence of provenance, depositional environment and the parameters obtained from Rock-Eval analysis accomplished with the Shale Play Method® developed at IFP Energies nouvelles (Pillot et al., 2014; Romero-Sarmiento et al., 2016a, 2016b): Sh0, Sh1, Sh2, Tmax, TOC, HI, OI, HCcont, MinC. TOC= total organic carbon, HI= hydrogen index, OI= oxygen index, HCcont= content in hydrocarbons, MinC= mineral carbon. Column names with –B and –E refer to analyses performed on bulk-rock and extracted organic matter, respectively. Table S2b. Same as in Table S2a for the samples from well core 12-36. Table S3a. Spreadsheet for well core 16-17 with the evolution of different properties with depth used for frequency distribution analysis with EasytraceTM software. The properties considered are: presence/absence of fractures (i.e. FRACTURE), the stratigraphic sequence (i.e. SEQUENCE), the depositional environment (i.e. ENVIRONMENT), the TOC values (i.e. TOC). Each line of the table represents a point virtually sampled along the log of well 16-17 to which information on the different properties were attributed via numerical codes (see Table 1). As requested by the software, the value “777” was attributed to the cells where information for a given property was not available. Table S3b. Same as in Table S3a for well core 12-36.

表S1a 钻井岩心16-17的研究样品详情，包含样品名称、深度、物源序列、沉积环境、裂缝数量、裂缝产状与运动学张开度、充填方解石的结构及其氧-碳-锶同位素组成。部分样品中，针对不同脉体或同一条脉体中的不同方解石结构开展了氧-碳同位素分析。
表S1b 针对钻井岩心12-36的样品，内容与表S1a一致。

表S2a 钻井岩心16-17的样品详情，包含样品名称、深度、物源序列、沉积环境，以及采用IFP Energies nouvelles开发的页岩层系分析法（Shale Play Method®）完成的岩石热解（Rock-Eval）分析所得参数：Sh0、Sh1、Sh2、Tmax、总有机碳（total organic carbon, TOC）、氢指数（hydrogen index, HI）、氧指数（oxygen index, OI）、烃类含量（content in hydrocarbons, HCcont）、矿物碳（mineral carbon, MinC）。该分析方法依据Pillot等（2014）、Romero-Sarmiento等（2016a、2016b）的研究成果。名称带–B和–E的列分别代表针对全岩（bulk-rock）与抽提有机质（extracted organic matter）开展的分析。
