Left-lateral shear deformation found in southern part of the Gaoligong range in west Yunnan and its tectonic implications

It is generally understood that the Tertiary structural deformation in the Gaoligong range in west Yunnan was under the control of right-lateral shear, resulting from the northward movement of Indian relative to Eurasian. In the southern part of Gaoligong range, however, we have recently found many pieces of evidence of left-lateral shear deformation, featuring a 10 km wide shear zone cutting through all tectonic elements of the range in N-S direction, which possibly occurred in late Tertiary time, and postdated the right-lateral shear. This is a significant discovery for revealing characteristics of the Tertiary intracontinental deformation of the Gaoligong range and the interaction between the Indian and the Eurasian continents.     

Modal extension rule

Modal logics are good candidates for a formal theory of agents. The efficiency of reasoning method in modal logics is very important, because it determines whether or not the reasoning method can be widely used in systems based on agent. In this paper, we modify the extension rule theorem proving method we presented before, and then apply it to P-logic that is translated from modal logic by functional transformation. At last, we give the proof of its soundness and completeness.
