Diagenesis of Luxembourg Sandstone
Research has been conducted into the diagenesis of the Luxembourg Sandstone. Literature studies were followed by a visit to the outcrop, after which thin sections were studied. The Luxembourg Sandstone Formation has been deposited in the Hettangian and Sinemurian, both lower Jurassic ages. A sea strait connecting the Northern German Basin and the Paris Basin was located in present day Luxembour...
متن کاملAnisotropy of sandstone permeability
Small-scale probe permeability measurements on differently oriented faces of highly compacted and quartz-cemented Viking Formation sandstones yield detailed permeability distributions that appear to be diagnostic of the grainand lamina-scale fabric of the samples. Permeability anisotropy of a single structureless'-appearing sample is low, reflected by a kV / kH-ratio of 0.7; corresponding k-di...
متن کاملDissolution of Magnesium from Serpentine Mineral in Sulfuric Acid Solution
As the volume of CO2, one of greenhouse gases linked to global warming, in the atmosphere increases, there has been an increasing interest in CO2 sequestration. Aqueous carbonation, which involves the extraction of Mg from serpentine minerals and the subsequent carbonation reaction with CO2 to form the geologically stable mineral MgCO3, has been proposed as a promising CO2 sequestration technol...
متن کاملSelf-Assembling Serpentine Robot
The Problem: The problem is to design an autonomous mobile robot that is self-assembling from independently mobile segments. We choose a design inspired by the constitution and motion of snakes or worms. In such a construction, the body of the robot is segmented and each segment can be designed as an autonomous entity, which is able to move and couple with other segments. Several of these segme...
متن کاملBituminous Sandstone Mixtures
In certain sections of the state of Indiana sources of recognized ag gregates for use in bituminous construction are very few, and the trans portation of aggregates to the job site from remote locations becomes necessary. Often the distance over which the aggregate must be moved is considerable, and the importation involves the expenditure of a size able sum of money, which it would be desir...
