EBSD data from quartzites of the Rengali Province and Eastern Ghats Province

The dataset consists of Electron Backscatter Diffraction (EBSD) data in .crc format, generated from quartzite samples at 0.5 micron and 1 micron step sizes. The quartzites are from the Rengali Province and Eastern Ghats Province; these are important geological terranes that comprise part of the Indian shield. Fine grained quartzites have been scanned at 0.5 micron step size and coarse grained quartzites have been scanned at 1 micron step size to ensure that orientation contrasts due to subtle lattice modifications in grain boundary domains have been adequately documented.本数据集包含格式为.crc的电子背散射衍射（Electron Backscatter Diffraction, EBSD）数据，采集自步长分别为0.5微米与1微米的石英岩样品。这批石英岩采自伦盖利省（Rengali Province）与东高止省（Eastern Ghats Province），二者均为构成印度克拉通（Indian shield）的重要地质地体。为充分记录晶界区域内晶格细微变化所引发的取向差，研究人员以0.5微米步长扫描细粒石英岩，以1微米步长扫描粗粒石英岩。
