Precambrian deposits are the dominant members of the IOCG group in terms of both copper and gold resources. These giant IOCG deposits are located in intracratonic settings within about 100 km of the margins of Archean or Paleoproterozoic cratons or other lithospheric boundaries. Their tectonic setting at formation was most likely anorogenic, with magmatism and associated hydrothermal activity driven by mantle underplating and/or plumes. Based on a review of isotopic dating data from the Kangdian Proterozoic rocks/minerals, three major geological events are suggested: the formation of the Kangdian basement of the Yangtze craton, 2486-1884 Ma, which would be as a part of Kenorland supercontinent; the Kangdian Continental Rifting located along the west margin of Yangtz craton, 1725-1466 Ma, which happened during the anorogenic period of Columbia supercontinent; metamorphism-magmatism events (1100-721 Ma) were the response to assembling and rifting of Rodinia supercontinent. The La-La IOCG deposit is hosted by the Kangdian basement of the western margin of Yangtze craton. The host rocks of the deposits are Proterozoic metamorphic rocks, Hekou Group, the protolith of which was the products of the Kangdian Rifting during 1712-1680 Ma, which contributed Stage I meneralization of the Lala IOCG deposit: Iron-P-REE. StageII (1000-900 Ma), with chalcopyrite (I) + magnetite (II) + molybdenite+purple fluorite + ankerite ± pyrite ± cobaltite ± quartz ±biotite (II) ± garnet (II) ± sericite, and StageIII（~850 Ma）, with dolomite/calcite+chalcopyrite±quartz, followed assembling of Rodinia supercontinent.
