  • The Jiajika ore deposit has become one of the areas with the richest Li resources in China and even in the world; nevertheless, remote sensing research on Li resources remains very insufficient. In this paper, geological mapping and oreprospecting studies in Jiajika area were conducted using remote sensing technology. Spectral library of typical rocks and minerals collected in this area was built, and spectral characteristics of rocks and minerals including biotite schist, grenatite schist, grenatite cordierite schist, hornstone, granite, spodumene-bearing pegmatite, pegmatite without spodumene, quartz vein, feldspar, spodumene monocrystal, biotite, and aquamarine were analyzed. Then geological mapping and ore prospecting were studied based on image processing and interpretation of middle spatial resolution remote sensing data LandSat 8 and high spatial resolution remote sensing data Geoeye-1. The results indicate that remote sensing technology is instructive for geological mapping and ore prediction of Jiajiaka type lithium ores and is likely to be a good indicator before geological study.
