Junction Deposit Carbonate Study EBSD

Electron back scatter diffraction data of carbonates from the Junction gold deposit near Kambalda in the Yilgarn Craton, Western Australia. Maps show relationships between phases as calcite is replaced by dolomite and siderite. Collection contains .ctf (Channel Text Files) which are ASCII files with phase and orientation data as euler angles. Note that dolomite is indexed using the calcite match unit due to problems with systematic misindexing of dolomite.

Two files are included for each map with suffixes 'Raw' and 'Processed' to indicate the as collected and final published data respectively.

本数据集为西澳大利亚州伊尔冈克拉通（Yilgarn Craton）坎巴尔达附近Junction金矿床的碳酸盐矿物电子背散射衍射（Electron back scatter diffraction）数据。图像展示了方解石被白云石与菱铁矿交代过程中的物相关系。数据集包含.ctf格式文件（通道文本文件，Channel Text Files），该类文件为ASCII格式，存储物相与取向数据（以欧拉角形式记录）。需注意：由于白云石存在系统性标定错误问题，本次采用方解石匹配单位对白云石进行标定。
每张图像对应两个文件，后缀分别为"Raw"与"Processed"，分别代表原始采集数据与最终发布的处理后数据。
