The pore geometries also affect their permeability. Imaging the visible pore space provides insights into the physical pore space, pore geometries, and the associated mineral and organic matter phases relevant for storage and transport. For example, organic-matter porosity is an important property of mature organic-rich shales providing storage capacity for liquids and gases, like hydrocarbons. Imaging the microstructure is the only technique which delivers data giving direct insight into the organic matter porosity. However, imaging porosity in fine-grained shale as well as carbonate rocks in a representative way at high resolution is challenging. https://www.leica-microsystems.com//science-lab/macroscale-to-nanoscale-pore-analysis-of-shale-and-carbonate-rocks/ Tue, 04 Sep 2018 22:00:00 +0000 PhD Jop Klaver, PhD Joyce Schmatz, MSc Mingze Jiang, PhD James DeRose https://www.leica-microsystems.com/17377 EM Sample Preparation Triple-beam Ar-Ion-Milling with a Rotary Stage to Decorate Grain Boundaries and Substructures in Rock Salt Decoration of grain boundaries in polycrystalline rocks has a long tradition in Structural Geology as in a monomineralic rock the recrystallized grain size is a good indicator for the paleostress conditions. Understanding the mechanical properties of rock salt and its deformation behavior is of major importance for the prediction of long-term stability of nuclear waste repositories, and our understanding of the dynamics of salt-related sedimentary basins which host the majority of oil and gas accumulations on Earth. https://www.leica-microsystems.com//science-lab/triple-beam-ar-ion-milling-with-a-rotary-stage-to-decorate-grain-boundaries-and-substructures-in-rock-salt/ Thu, 03 Mar 2016 11:01:00 +0000 PhD Joyce Schmatz, PhD Oliver Schenk, PhD Jop Klaver, PhD Janos Urai, PhD Wolfgang Grünewald
