Define macro minerals1/22/2024 ![]() ![]() ![]() New Macro Analytical Methods Development - This task provides for the coordinated research and development of new analytical methods needed to meet the needs of projects administered under the Mineral Resources Program and other USGS projects as needs arise. The Project is responsible for maintaining the availability of analytical instrumentation, laboratories, techniques and staffing for use by multiple USGS projects and for maintaining specialized in-house capabilities for use in characterization of difficult to analyze sample matrices beyond the capabilities of the contract laboratory.Ī selection of analytical equipment in Geology, Geophysics, and Geochemistry Science Center laboratories.(Public domain.) Project members also develop methods for specialized analyses via reimbursable projects for other DOI and U.S. Another key goal of the project is to evaluate the need for and develop new natural matrix geochemical standard reference materials that are used by USGS and other scientists to calibrate analytical instrumentation, validate methods and models, and monitor laboratory performance. Our scientists ascertain what types of new and emerging analytical techniques USGS will need with the next several years to support programmatic research efforts and to develop those techniques using existing instrumentation or by obtaining the necessary equipment and instrumentation. For many projects carried out by the USGS, there are no commercial laboratories that can provide the unique types of geochemical analyses or the high quality data required to carry out the project objectives. Development of new, state-of-the-art analytical methods can be applied to topical studies in energy and minerals, environmental health, ecosystems, land resources use, water quality, and natural hazards. ![]() ![]() Both macro and micro analytical methods use a variety of analytical instrumentation including: Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES), X-ray Fluorescence (XRF), X-ray Diffraction (XRD), Raman Spectroscopy, and Cavity Ring-Down Spectroscopy (CRDS). Generally macro analytical methods examine the bulk elemental, chemical, or mineralogical composition of a sample while micro analytical methods use specialized sample introduction devices or instrumentation to examine how the elements or minerals are spatially distributed in a sample. The Macro and Micro Analytical Methods Development Project provides access to the expertise of highly experienced research scientists and state of the art analytical instrumentation to develop new and unique analytical capabilities to solve complex problems beyond routine analysis. Routinely, the success of these projects is reliant upon access to state-of-the-art instrumentation and methods of analysis. Many projects funded by the Minerals Resources Program and other USGS mission areas use chemical analysis as a tool to study a variety of mineralogical, ecological, environmental, and biological processes. USGS reference material matrix sampling, geochemical reference materials, analytical laboratory equipment, and sample data. (Public domain.) Science Issue and Relevance ![]()
