| Analysis on the Ore-forming Geodynamics of the Baiyangping Ore-concentrated Field, Yunnan Province |
| The Baiyangping ore concentrated field is located in the northern segment of the Lanping Simao India Yanshanian Ximalayaian ore forming belt. Based on the field measurement and reconstruction of the rock's tilting history, the ore forming geo dynamics is analyzed by the method of anti graphic solution using the sprout conjugate joints. The result shows that the Ximalayaian tectonic movement can be divided into three stages. The first stage manifested by the strongly folding in the edge of the Yunlong Jiancheng fold system and bending inside basin was followed by the second stage deformation, brittle deformation shown as the formation of SN trending thrust in the whole fold system and wide-spread folds outside of the basin. The last stage deformation was cha racteristic by regional extension and compression in turn. |
