Potential for constraining sequence stratigraphy and cycle stratigraphy with U-Pb dating of carbonates
Studies of sequence stratigraphy and cycle stratigraphy in carbonate formations increasingly improve our understanding of depositional systems and basinal to global correlations. However, there is still a scarcity of dated sequences to determine the time length of sequences and cycles. Furthermore, the durations of sequences and cycles provide tests of the processes that produce them. Poor age resolution mostly stems from the lack of recognizable volcanic ash deposits in many sections. Through continuing advances in analytical techniques and approaches to sampling, the current state of Usingle bondPb dating of carbonate sedimentary rocks provides opportunities to fill in age gaps. The approach should build on well-constrained 3-dimensional stratigraphic architectures and diagenetic stratigraphies.
Utah FORGE: Well 16B(78)-32 Core Photographs
This dataset includes images of core samples collected from Utah FORGE well 16B(78)-32. The images are stitched photographs showing the circumferential view of the cores exterior in two dimensions and the individual photos of the core taken at multiple angles used to construct the stitched photos.
Mt. Simon Sandstone - High Resolution CT
High resolution micro-computed tomography images of sandstone from the Mt. Simon formation at different depths. These images provide an insight into the pore structure of the Mt. Simon sandstone (e.g. for potential CO2 storage). This data set can be used to further study the formation as a whole..
