GEOLOGIC CHARACTERISTICS AND PROSPECTIVE POTENTIAL OF THE XIAOWANGGOU IRON DEPOSIT IN LIAONING PROVINCE

The Xiaowanggou iron deposit is located in a nearly triangular area controlled by Hanling fault, arcuate Dengta fault and Shiqiaozi fault, with developed structure and broad distribution of magmatic rocks. Due to the inhomogeneity of the hypometamorphism, the Archean Anshan group Cigou formation is distributed in the migmatitic granite in the form of residues, in which ore bodies occur. There are two large ore bodies, most of which are buried in the migmatitic granite, less exposed in the surface. Chloritization, actinolitization, muscovitization and sericitization are common in the wallrocks and the orebodies. Study of the regional geology, deposit geology and genetic types of the deposit and analysis on the characteristics of the form, distribution, extension and genesis of the ore (mineralized) body show a great prospective potential of exploration in this area.
