Abstract
Subfabric studies of calcite from an Aravalli marble have been carried out by measuring [0001], e-lamellae, r-cleavages, and a-axes in each grain in the rock-slide. The coaxes maximum is located nearly normal to the regional foliation (S2-surface), thus conforming to the results of the experimental deformation of calcite. The orientation of [0001] is attributed to the syntectonic recrystallization accompanying the first deformation D1; while the (0112) orientation appears to be related to the late phase of D1 or possibly to the second deformation, D2, which refolded the Aravalli rocks and the underlying Banded Gneissic Complex. The two deformation phases have been established on the basis of different structural elements in the rocks of the investigated area.
