One of the main advantages of chemostratigraphy is its utility with strata of almost any age from any geological setting as diverse as carbonate platforms to tidal bar sandstones to deep marine turbidites. Chemostratigraphy is not restricted by lithology or sample type. It can be applied to samples of any lithology (including but not restricted to claystones, sandstones, volcaniclastics, coals, carbonates and evaporites) and equally as well in core, side wall, outcrop and well cutting samples, including turbine- drilled cuttings. Analyses can also be performed on a small amount of sample (minimum of 0.25 grams) where sample volumes are limited. The sample quality is most important, especially in well cuttings, so initial preparation involves ”picking” the desired lithology and washing to remove drilling fluid contamination prior to grinding and milling.
