... in this paper is aimed at understanding the strength and microscale mechanical and chemical properties of the vitrified material to see what is happening to the rock, specifically Basalt, pre- and post-melting by using a series of experimental and analytical tools. 1. INTRODUCTION With global energy...

... ABSTRACT CO 2 wettability and the reservoir rock-fluid interfacial interactions are crucial parameters that regulates the successful CO 2 geological sequestration. This study implemented the feed-forward neural network to model the wettability behavior of Saudi Arabian (SA) basaltic rocks...

... ABSTRACT One way to mitigate global warming is to withdraw CO 2 from the atmosphere and inject it into deep formations of porous basalt to form carbonate minerals that can bind large quantities of CO 2 . Such formations are found in many places in the world. The process is to some extent...

... in Iceland and eastern Washington state. In this work, we conduct a comprehensive literature review on the properties of mafic and ultramafic rocks such as basalt, gabbro and peridotite. We examine the ranges of material properties and their correlations as well as rock mass characteristics...

... ABSTRACT On 17 December 2020, China's Chang’e-5 mission returned about 1.73 kg of lunar regolith from one of the youngest basalt units in northern Oceanus Procellarum. The mineralogy of the lunar surface regolith provides a wealth of information on its geological history...

... ABSTRACT: The Boise Valley contains several columnar jointed basalt cliffs, which were deposited approximately 1.4 to 0.5 Ma on terraces formed by downcutting of the Boise River. Three runout talus deposits on Whitney Terrace were characterized using unmanned aerial vehicle visual imagery...

..., a series of Brazilian tests on specimens of different sizes was carried out with four different brittle rocks, including granite, basalt and two types of monzonite. From the results, it is concluded that the problem associated with the undesirable shear failure developed in the vicinity of the contact...

... Abstract: Columnar jointed basalt is a discontinuous rock mass system that exhibits strong anisotropy in deformability and strength. Discrete element methods and the new continuum constitutive model (Comba model) are two approaches for numerical simulation of columnar basalt. The mixed...

... Abstract: Using a systematic approach for selection of drill bits, including testing on basalt rock samples and up front use in test wells, leads to significant improvement of performance. Additional focus on modeling and planning of BHAs (Bottom Hole Assemblies) improve stability...

... and retaining walls reaching 490m in length and up to 22m high. The geology at Sexton Hill comprises a volcanic succession of variably weathered basalt flows and agglomerate deposits overlying Mesozoic sedimentary rocks at a depth of approximately 48m beneath the crest of the hill. From design through...

... material: CRF Strengths have increased 20-30% with the switch from basalt to the limestone aggregate. 2) Cement and cement to flyash ratios: The average CRF strengths have increased over time, even as we have decreased cement by supplementing it with fly ash. The original formula recipes had cement...

... a specimen would also be valuable parameters. Vesicular basalt specimens obtained from surface boulders from southern Nevada were used in this study. In terms of mechanical strength, basalt is one of the most competent of all rocks. Formed by extrusive volcanic action, it commonly has a micro-fine texture...

... ABSTRACT ABSTRACT: Understanding and predicting the intact strength of rock is very important in design of foundations, tunnels, and in other engineering projects. The presence of vesicles within basalt has a direct impact on the unconfined compressive strength (UCS) of the intact rock. Over...

... rock core-samples from nearly 200 boreholes along an approximately 12 km's length of a sewerage tunnel alignment in both Siltstone and Basalt. This paper presents some previously unpublished laboratory testing data on the engineering properties of Siltstone and Basalt. Also included is an examination...

... ABSTRACT: The Annapolis Valley located in western Nova Scotia, Canada, represents the southern-southeastern extension of the early Mesozoic Fundy Rift Basin. Its northern ridge reaches 220 m above the valley floor and is formed by a Jurassic basalt cap that overlays fractured sedimentary rocks...

... ABSTRACT: A design of the roller compacted concrete dam, 85 m high with a crest length of 705 m, was carried out to provide flood storage on the lower reaches of the Imjin river. The alluvium layer between gneiss and basalt rock masses, varying from fine silty clay to cobbles mixed with sandy...

... ABSTRACT: Cross-borehole air-injection interference tests were conducted at the Box Canyon site near the Idaho National Engineering and Environmental Laboratory in order to assess the pneumatic connectivity of unsaturated fractured basalt, and determine zones of preferential flow. Data...

... ABSTRACT: The continental flood basalts of the Columbia Plateau, Washington State, have been deformed into a series of anticlines termed the Yakima Fold Belt. These periodically spaced folds may be associated with buckling instability of a basaltic layer overlying a sedimentary substrate...

... of a soft ultramafic hangingwall and a relatively stiff and strong basaltic footwall. It is intersected transversely at many points by a set of quartz porphyry dykes which exhibit frequent bursting behaviour when exposed. The rock bursting is currently thought to be caused by tensile strain energy release...
