·By definition basalt is an aphanitic fine grained igneous rock with generally 45 53% silica SiO 2 [] and less than 10% feldspathoid by volume and where at least 65% of the rock is feldspar in the form of plagioclase This is as per definition of the International Union of Geological Sciences IUGS classification scheme
·Quick facts and properties Name Basalt Rock type Igneous Origin Extrusive Texture Fine grained or aphanitic with grain sizes less than 1/16 mm but may be porphyritic vesicular subophitic ophitic or amygdaloidal Colors Dark gray dark green gray greenish black to black Cooling rate or history Fast on the Earth s surface Chemical composition Mafic or basic
·Experimental rock mechanics has traditionally been executed in the fields of civil engineering and mining as well as structural geology with a focus on sedimentary and P R and Kilburn C R 2003 Flow and fracture maps for basaltic rock deformation at high temperatures J Volcanol Geotherm Res 120 25 42 doi
·Schaefer et al Geomechanical rock properties of a basaltic volcano FIGURE 9 A Static Young s Modulus plotted against the sample strength for all but the cyclically loaded samples
·This methodology has shown % accuracy to automatically identify the textures of basaltic rock using digitized image of thin sections of 140 rock samples and can be used to identify the texture of rock fast and accurate in geosciences A new approach to identify the texture based on image processing of thin sections of different basalt rock samples is
Basalt is an extrusive igneous rock It is the bedrock of the ocean floor and also occurs on land in extensive lava flows Much of the Moon s surface is underlain by basaltic lava flows and flood basalts These areas of the Moon are known as "lunar maria " Large areas of the Moon have been resurfaced by extensive basalt flows which may have
·testing of basaltic rock and rock masses has been done as part of the large scale Basalt Waste Isolation Project at the Hanford site Washington State during the late 1980 s Department of Energy 1988; Cramer et al 1987 The project report has provided a valuable new data base on the deformation properties of basaltic rock masses that
·Basalt is both a highly reactive and wide spread silicate rock Basaltic volcanic and subvolcanic rock occupies × 10 6 km 2 or % of the land surface of the Earth Underground CO 2 injection into basalt and mining of basalt for fertilizer production are likely to compete for space if conducted on a large scale About % of the Earth
·Along with temperature pressure and melt chemistry magmatic oxygen fugacity fO2 has an important influence on liquid and solid differentiation trends and melt structure To explore the effect of redox conditions on mineral stability and mineral melt partitioning in basaltic systems we performed equilibrium one atmosphere experiments on a
·Weathered rock columnar basalt at Cape Stolbchaty in Russia The volcanic rock could be used to soak up carbon dioxide from the atmosphere Courtesy Ekaterina Vasyagina/CC BY SA Sprinkling powdered basalt over natural ecosystems would remove vast amounts of carbon dioxide from the Earth s atmosphere while also improving soils
·The deformation characteristics of basalt rocks subjected to cyclic uniaxial stress and cyclic temperature were investigated and a corresponding damage model was established Cyclic uniaxial stress temperature tests were conducted in which stress upper limit was 80% or 65% of the uniaxial compressive strength and peak temperature was 60 °C or 90 °C
·This method is operated above ground and involves the reaction of feedstock fly ash waste from the steel and iron industries ground reactive rock and mine tailings with CO 2 in a gas stream to
·Blasting remains the most economic method of rock excavations however the losses associated with the blast induced damage is becoming cause of concern for safety and productivity among the mining and civil projects Rock mass damage in underground openings occurs mainly due to blast induced forces stress redistribution and weathering
·In fact mafic basalt is the most widely distributed igneous rock constituting about 70% of the oceanic floor and >5% of the land area as shown in Fig 1 CO 2 sequestration in basaltic rock at the Hellisheidi site in SW Iceland stratigraphy and chemical composition of the rocks at the injection site Mineral Mag 72 1 2008 pp 1 5
·Silica rock dust is in most cases waste from rock mining which is commonly discarded The residue may have several minerals that when properly applied can improve soil fertility and plant growth Therefore the use of basaltic rock dust in agriculture allows for soil fertility improvement releasing nutrients and inducing soil pH
·Basaltic rock units exposed on the way from Dejen to Lumame shows gentle slope since it is the top part of the flood basalt From Lumame through Robgebya to Mt Choke the slope rises progressively indicating the start of shield basalts Samples around Lumame and Chemoga areas are slightly porphyritic in texture
·The present rapid trend for civil infrastructure projects and urbanisation is demanding for more tunnelling and underground space generation Blasting remains the most economic method of rock excavations however the losses associated with the blast induced damage is becoming cause of concern for safety and productivity among the mining and civil
·In the past few decades substantial studies have been carried out on the response of CJRM Differences in the mechanical anisotropy of CJRM in various directions were observed by various field tests elastic moduli tests P wave velocity measurements and point load determination 9 10 The development degree of columnar joint network and rock
·Damage assessment of basaltic rock mass due to repeated blasting in a railway tunnelling project A case study March 2009 Tunnelling and Underground Space Technology 24 2 208 221
·Huge water inflow with highly to completely weathered basaltic rock mass encountered for about 15 20 m length where TBM progress drastically reduced as the TBM operational parameters were adjusted to avoid any ground loss and passed the zone without causing any ground settlement on slums located on surface Department of Mining
1 ·It is the most common rock type found in oceanic crust and is an Basalt is a dark colored dense rock composed primarily of plagioclase feldspar and pyroxene It is the most common rock type found in oceanic crust and is an Basaltic magma forms from the partial melting of the Earth s mantle particularly in tectonic settings like mid
·Empirical relationships for estimating Uniaxial Compressive Strength UCS of rock from other rock properties are numerous in literature This is because the laboratory procedure for determination of UCS from compression tests is cumbersome time consuming and often considered expensive especially for small to medium sized mining engineering projects
