Cosmogenic ¹⁰Be surface exposure dating
Standard method for determining exposure ages of rock surfaces using in-situ produced cosmogenic ¹⁰Be nuclides measured by accelerator mass spectrometry. Involves sample collection, quartz purificatio...
High-resolution meander delineation using NHD and DEM data
Integration of USGS Digital Elevation Models with National Hydrography Dataset to accurately delineate stream meanders for hydrological modeling when standard DEM resolution is insufficient.
Strontium isotope analysis
Systematic sampling and isotopic analysis of carbon, oxygen, strontium, and sulfur from carbonate and sulfate minerals to determine paleoenvironmental conditions. Integration of multiple isotopic syst...
Geochemical analysis
Chemical analysis of igneous and meta-igneous rock samples to determine composition and petrogenesis. Results presented in tables and geochemical diagrams.
Geospatial data compilation
Integration of new and compiled geologic mapping data with geospatial analysis for neotectonic and hydrologic investigations.
Laser ablation ICPMS U-Pb dating
Laser ablation inductively coupled plasma mass spectrometry used for U-Pb detrital zircon geochronology analysis. Supports mapping and stratigraphic interpretations of Paleozoic sedimentary rocks.
Pollen analysis
Analysis of pollen from archaeological site sediments to reconstruct past vegetation.
SEM-cathodoluminescence
Scanning electron microscopy with cathodoluminescence imaging for characterizing zircon internal structure.
