How to Describe and Interpret Evaporite Core

Course Details

This course is conducted at the United States Geological Survey Core Research Center (USGS-CRC) in Lakewood, Colorado, USA – one of the largest laboratories in the world where core is collected and stored. Not only is there a large room where several hundred meters of the core can be displayed at a time but there is also a classroom where lectures can be delivered. The course will run for 2-days and participants will get to log at least 50 meters of core on a cm-scale. We believe that one learns by doing and not watching and at the end of the course participants will be confident in their ability to describe and interpret evaporite core from a wide range of depositional environments.

If your interest lies in something specific (Potash for example), please let us know in advance so we can arrange cores that would be relevant to your learning objectives.

Who Should Attend

Oil and professionals and Graduate Students who are working on the exploration and development of carbonate-evaporite successions and mining geologists and engineers who are working on gypsum, potash, and rock salt.

    Course Outline

    Day 1

    I. Lecture on how to approach a core facility, equipment and instruments, photographing core, washing core, integration with well-logs, choosing the right template, primary evaporate textures, and depositional environments.

    II. Core logging using examples from the Williston, Permian, and Paradox Basins.

    Day 2

    I. Lectures on secondary evaporite textures, grade calculations for Potash, use of handheld Gamma Ray spectrometers, and creation of core-based logs.

    II. Core logging using examples from the Williston, Permian, and Paradox Basins.

    Core viewing at the USGS-CRC is in high-demand and to book the facility for three consecutive days is not easy and has to be done at least 5-6 months in advance. Therefore if you are interested in taking this course within the next 6 months, the booking has to be made as soon as possible to secure a spot. If you are wanting to take a five-day extended version of this course, we can arrange that.

    If you would like to arrange this workshop on your core we can do this at a location of your choice in the US or overseas. If you are wanting us to arrange this course using your core, please send us core and thin-section photos at least three months in advance.


    Our location

    Our headquarters are twenty minutes away from downtown Denver and half an hour from the largest core facility in the United States. Or field office in Ouray allows us quick access to world-class outcrops in Utah and New Mexico.
