Lower Palaeozoic Unconformities in South-western Tasmania
Recent geological work in south-west Tasmania on a regional scale has allowed the compilation of existing information regarding Lower Palaeozoic unconformities, namely the description of new localities and in some cases the amplification and extension of previously described exposures. Carey and Banks (1954, p. 245) provide a review of information to 1954 and their classification of unconformit...
متن کامل3D seismic image processing for unconformities
We propose a 3D seismic unconformity attribute to detect complete unconformities, highlighting both their termination areas and correlative conformities. These detected unconformities are further used as constraints to more accurately estimate seismic normal vectors at unconformities. Then, using seismic normal vectors and detected unconformities as constraints, we can better flatten seismic im...
متن کاملPicking a Pooling
We introduce a concept we call “mutual metainformation” as a criterion for determining the maximum statistically significant number of clusters in distributional clustering problems. In distributional clustering, one has data drawn from an ensemble of probability distributions and seeks to group similar distributions together. We focus on the case of multinomials, such as a set of biased coins ...
متن کاملManipulating picking sequences
Picking sequences are a natural way of allocating indivisible items to agents in a decentralized manner: at each stage, a designated agent chooses an item among those that remain available. We address the computational issues of the manipulation of picking sequences by an agent or a coalition of agents. We show that a single agent with additively separable preferences can compute an optimal man...
متن کاملShort Note Semblance picking
Tomography in the post-migrated domain is quickly becoming the standard approach for obtaining velocities in complex areas. The standard flow to update the velocity through tomography in the post-migrated domain begins by migrating the data using some initial velocity model. This migration method can be Kirchhoff (Etgen, 1990), downward continuation methods (Clapp, 2001b; Mosher et al., 2001), ...
