Geology Facilities

About the Lab

The Environmental Mineralogy Imaging Lab offers access to imaging and analytical characterization technologies to WSU faculty, staff, and student researchers.  This facility is also available to researchers from other universities, foundations, and industry.

In addition to instrument access, EMI personnel offer advice, hands-on training, education, and research collaboration.  Our goal is to promote, enable, and encourage cutting-edge education and research using the lab’s instrumentation.

Instrumentation

The EMI lab contains a Thermo Scientific Phenom Pharos desktop Scanning Electron Microscope (SEM) with a Field Emission Gun (FEG).  The instrument is equipped with BSE, SE, and EDS detectors allowing for morphological, compositional, and chemical analysis of materials.  This SEM has a maximum magnification of 1,000,000x with a resolution of 2.5 nm (SE), and can operate in a variety of accelerating voltages and vacuum modes.  Analytical capabilities include elemental mapping & line scanning as well as 3-D roughness reconstruction.

The Rigaku Mini Flex II X-ray diffractometer can determine: crystalline phase identification, percent crystallinity, crystallite size, and lattice parameter refinement. For data analysis the MDI Jade software is interfaced with databases from the International Centre for Diffraction Data.

The EMI lab is primarily equipped for preparation of geologic materials such as bulk rock, sediment, soil and clay samples, with tools including a puck mill, centrifuge, ultrasonic probe, desiccators, drying oven, heating water bath, and vacuum filtration.   Additionally, the lab has a Cressington 108 Sputter coater with a Au target for non-conductive SEM samples. 

Schedule and instrument scheduling

The regular hours of the EMI will be from 8:00 a.m. to 5:00 p.m. Monday through Friday. 

Instrument scheduling: Qualified users that have undergone training and demonstrated proficiency will be allowed  unsupervised use of EMI equipment.  All other use will be supervised by EMI personnel.

Rates

Prices effective April 1st 2021 and are subject to change. Please contact  personnel with any questions or concerns. 

All users must supply all disposable materials needed for their work; we endeavor to keep common supplies at-hand for use. 

Charges: Users are charged for the SEM at an hourly rate.  This rate includes use of any detectors (BSE, SE, EDS) and software (elemental mapping, 3-D roughness) required by the user.  Users of the XRD are charged on a per-scan basis and this charge includes use of the Jade software and ICDD database. 

Charges for use			Internal		External
Scanning Electron Microscopy
Phenom Pharos			$46.00/hr		$75.00/hr
X-Ray Diffractometer
Mini Flex II			$21.00/scan		$35.00/scan

 

What are the reasons to justify these costs?

• Field Emission Gun and vacuum system – The FEG source for the SEM has a lifespan of ~10,000 hours while the vacuum system requires periodic pump maintenance. The annual service contract for this maintenance is approximately $16,000.
• X-ray tube – The Cu X-ray source in the XRD degrades over time. The expected lifetime is around 5 years and the cost of replacement tubes is approximately $4,000.
• Materials and supplies – Copper tape, aluminum stubs, carbon tape, weigh boats,  methanol, safety equipment (gloves, eye protection), replacement glassware, computers and paper, sputter coater targets etc. that are utilized by most lab users must be replaced.
• Database renewal – The ICDD PDF-2 Scholar package, providing the latest database access, support, and updates through spring of 2024.  This subscription requires renewal at a cost of approximately $6,000.

The department houses a wide variety of field equipment for field mapping, measurements, and sample collection.

The department also has a field portable handheld SciAps XRF for in-field elemental analysis. The unit is calibrated with 37 standard elements including all measurable pathfinders except REE’s.  

The department has retained a large collection of rock, mineral, and fossil samples since its founding in 1926. These resources are vital for teaching and research by our faculty and students.

The Hydrogeologic Research and Teaching Field Site was made possible through generous donations from GSI Engineering (http://gsinetwork.com/) and the Kansas Geological Foundation.  Located on an ~10 acre area of the larger Ninnescah Reserve (https://www.wichita.edu/academics/fairmount_las/bioscience/fieldStation/MapNinnescah.php), the Site consists of nine 2" groundwater observation wells (20-25' total depth) and one 6" pumping well (20' total depth) screened in alluvial sands along the Ninnescah River.

• Groundwater well location map

GSI Engineering completed geoprobe borings and EC characterization in 2018, and completed groundwater well installation in November 2019.  This facility provides WSU students with a location to gain real world experience with activities frequently used by professional geologists such as groundwater level gauging, pump tests, slug tests, and low-flow groundwater sampling.  The proxity of the wells to the Ninnescah River allows students to study the relationship between river stage and groundwater level in the alluvial aquifer.  Located in one of the managed prairies at the Ninnescah Reserve, the groundwater wells also provide a research site to investigate the impacts of land managment practices (burning, mowing, etc.) on groundwater levels and groundwater chemistry.  This facility is open to use by reseachers outside of WSU.  Anyone interested in using this facility is encouraged to contact Dr. Swindle (andrew.swindle@wichita.edu)

Located in the Flint Hills region of Kansas, the Youngmeyer Ranch provides a convenient location to explore concepts related to stratigraphy, structure, geomorphology, and hydrology.

Northwest College facilities in the Bighorn Basin of Wyoming and Montana provides annual summer access to teaching and research opportunities in deep-time stratigraphy, structure, and geomorphology.
