Tieshan in southeast Hubei Province is the first area where bone-shaped boudinage was discovered in Asia. To acquire the distributing diagrams of relating parameters such as true differential strain (ε₁-ε₂), kinematic vorticity (Wk) and orientations of the major axes of the finite strain ellipse, the finite strain measurement at different positions in the matrix of asymmetric bone-shaped boudinage in this area was carried out by inertia moment ellipse method. It is shown that the finite strain in matrix of the asymmetric bone-shaped boudinage is controlled by its competent layer, namely negatively related to the distance away from the competent layer and to the granularity of minerals in the matrix. The finite strain in matrix also shows larger in its thinned sections than that in thickened sections along direction of its elongation.
