Structural geology research with dr. randy merrett

Dr. Randy Merrett is an Associate Professor in the Department of Geological Sciences at the University of Texas. Dr. Marrett's research concentrates on deformation processes in the upper continental crust where folds, faults, and opening-mode fractures are the most important products. This work is applicable to a wide range of human concerns such as natural hazards (eg, earthquakes, volcanoes) and the flow of fluids through rock (eg, hydrocarbons, water, contaminants). Some common themes that relate his disparate interests are quantitative field observations and analysis, especially using techniques that address spatial and size scaling of structures. Dr. Marrett currently has on-going projects that address active faulting and geyser eruption patterns in the Central Andes of Argentina and Chile, detachment folding and curved orogenic belt development in the Sierra Madre Oriental of Mexico, and opening-mode fracturing in numerous areas.

Green river utah structural geology 3d visualization

The geological maps seen in these visualizations are constructed using data from a publication titled "Geologic Map 180" created by the Utah Geological Survey, a division of the Utah Department of Natural Resources (we have obtained permission from the UGS to use this publication as a basis for our visualization). The maps are authored by Hellmut H. Doelling of the Utah Geological Survey in the year 2001. The elevation surface of the region is modeled from the National Elevation Dataset using 10m spaced data points and Landsat natural color mosaics are applied as surface textures in the non-geographic overlay version of the animation. Our visualization begins with a north-up overhead view of an area of Utah between Green River and Moab. The La Sal mountains are in the lower right portion of the viewpoint. Both Landsat satellite imagery and geological interpretive maps are overlaid onto a flat surface, which will later become three dimensional. As the camera moves into position near the South East corner of the working area, the geologic cross sections will be extruded to true height above sea level, reaching vertically out of the flat terrain surface.

A pull apart basin is a basin formed when a kink or bend in a strike-slip fault forms a releasing section with normal faults along strike. This simple block model shows a simple example of a pull apart basin with two offset strike slip faults and two normal faults at ninety degrees to the strike slip faults that define the centre block that moves down with increasing slip.

The evolution of mullions (structural geology, low quality)

Mullion structures in the Lower Devonian of the Ardennes and Eifel have been discussed in the literature in three languages since 1907. An outcrop in Dedenborn, Germany, served as example in several textbooks for mullion type locality. This structure is characterized by cylindrical cuspate-lobate structures on pelite-psammite (yellow and pink) contacts, with the regional slaty cleavage (red plane) at a high angle to bedding. In the more competent layer, quatz veins (white) formed. This movie combines some observations of these structures, and gives an animation of how these structures evolve from boudin structures by a later stage of compression. The pelite-psammite interfaces are pined at the quartz veisn, forming cuspate intefaces. A review of the confusing evolution of nomenclature, the models proposed for their evolution, and present data from a database of 150 outcrops containing mullion structures is provided in the paper: Urai, J., Spaeth, G., van der Zee, W. and Hilgers, C. 2001.

Preparing an analogue experiment box (structural geology)

Ever wondered how much effort it is to prepare an analogue geological model? This movie shows in 361 time steps how the deformation box is filled. The experiment being set-up contains a single sand layer, which is filled in the box using a funnel-shaped car. The hemihydrate is "whiped" through the stainless steel net, tensioned in a sieve-table, using rubber sheets and cardboard rolls. In this movie a relatively simple experiment is prepared, but the total time covered in this movie is 2 hours. Then it tales two hours to run the experiment (see for example: www.youtube.com ) and another hour to clean up. This movie is taken from the MSC-thesis of Heijn van Gent.

Sampling in wadi dam (structural geology fieldwork)

This video shows some impressions of our January 2010 field work in Oman, narrated by Simon Virgo (in German). For more information: www.ged.rwth-aachen.de or bit.ly/FRACs The main aim of this project is to understand the role of existent veins, which act as heterogenities to fracturing depending on orientation and their sealing-driven strength regeneration. Secondly, to understand the growth of crystals from oversaturated fluids in fractures is the other major aim of this project. Crystal growth appears as a back-coupled system with fluid flow and material transport in fractures. The growth of crystals and the growth of the vein respectively is influenced by the stress state in the system as this might open the fracture again. This study is carried out within the framework of DGMK (German Society for Petroleum and Coal Science and Technology) research project 718 "Mineral Vein Dynamics Modelling", within the basic research programme of the WEG Wirtschaftsverband Erdöl- und Erdgasgewinnung eV We thank the companies for their finacial support and their permission to publish our results.

Folding of a single, thick silicone layer (structural geology, analogue modelling)

Folding of a single, thick silicone layer, embedded in a matrix of isolation foam. In this playlist, some movies of the analogue folding of silicone layers, embedded in a foam matrix are shown. We built these models to demonstrate single- and multilayer folding in rocks in the classroom, more or less following the figures in John Ramsay's book. They are large enough for classroom use, quite light weight and can be deformed by hand in front of the class. They can be re-used. We used compressible elastomers instead of viscous materials to get the right effect, as this allows volume change and even a king of axial plane cleavage to form. If there is sufficient interest we would consider offering these models as a teaching set and have a company produce a batch. If you are interested please let us know: j.urai@ged.rwth-aachen.de.

Slices of naxos pegmatite boudins (structural geology, hq)

In spectacular marble quarries near Kinidaros (Naxos, Greece) the three dimensional geometry of the boudins is exposed, which formed during ductile deformation of marbles under high grade metamorphic conditions. The studied block consists of marble, pegmatite and amphibolite. It was cut into 34 slices with a thickness of about 2 cm. Pegmatites enclosed in the marbles were deformed in a brittle fashion forming blocky boudins with quartz veins in the inter-boudin zones. The pegmatite is 6 to 8 cm thick and boudinaged, while the 2 to 3 mm thick layer of amphibolite has a wavy shape following the enveloping surface of the boudins. This image sequence provides three-dimensional information on the internal evolution of the fractures inside the pegmatite. This is work by Oliver Schenk. For more information, have a look at Schenk, O., Urai, JL & van der Zee, W. 2007.

Rotating 3d structural cube under aachen (structural geology)

This is a rotating 3D structural geological cube of the crust under the city of Aachen and parts of the Eifel in Germany. f you are interested in the subsurface of Aachen and the Eifel, you can use this Google earth file. It will generate a cube in the subsurface of Aachen, with Geological profiles pasted to it's sides. You can move it up and down using the calendar bar in the top left (behind the logos). This is the Google Earth Version of the Eifel Cube developed by the GED and GIA. Originally, this cube was designed by Prof. Dr. Gerd Flajs, Prof. Dr. Roland Walter, Dipl.-Geol. Oliver Schenk, Werner Kraus and Marius Brundiers. When you load the cupe for the first time, make sure that you have image compression activated. The checkbox is located under Tools, Options, 3D View, Texture Colours. Without compression it will take a lot longer to load or might even crash the computer. If you want to have more information, have a look at www.ged.rwth-aachen.de. You can also integrate this cube in Google Earth.
