 Chemical analysis of mechanically homogenized bulk-rock samples is a highly cost-effective way of obtaining highly quantitative data for a wide range of chemical variables, including alumina, U, Th, K, and TOC. Many chemical components uniquely track mineral abundances or are closely related to wireline-log responses. These data are useful for comparing different lithofacies and geographic locations, and can be used for stratigraphic correlation (Chemostratigraphy). In-house capabilities for bulk chemical analysis consists of X-ray fluorescence (XRF) spectrometry, inductively coupled plasma atomic emission spectrometry (ICP-AES) and several wet-chemical methods. |
