Free Webinar: Multiscale Microstructural Analysis of Rocks

10 Oct 08:00 – 09:00 UTCWebinar

Most rocks have a porous structure and irregular shape that consists of inorganic and organic parts. That makes their preparation very tricky. The combination of ion milling with a special mechanical pre-preparation makes it possible to prepare perfect surfaces of rocks usable for examination with optical microscopy and SEM, but also for surface analytical methods.
In the first part of this webinar, Dr. Wolfgang Grünewald, expert for sample preparation for electron microscopy and optical microscopy at Leica, will explain how to prepare rock samples with ion milling.

In the second part of the webinar, Dr. Joyce Schmatz, a Geologist with specialization in microstructural analysis, will present multiscale imaging technologies combining the advantages of novel virtual polarizing microscopy (ViP) with high-resolution scanning electron microscopy on broad-ion-beam polished sample cross-sections (BIB-SEM). In her presentation, she will focus on quantification of pore properties (meaning pore sizes), pore connectivity, pore fluids and associated mineralogy, at the cm to nm scale of carbonates and mudstones. Recent developments in using ion milling for standardized protocols for light reflectance measurements of vitrinite particle surfaces (a.k.a. vitrinite reflectance) will also be covered.

In this webinar, you will learn about:

  • How to prepare rock samples with irregular shapes
  • How to polish large rock surfaces for multiscale imaging technologies
  • How get to know the unique combination of mechanical pre-preparation tool and ion milling system
