- 1From:Journal of Petroleum Exploration and Production Technology (Vol. 10, Issue 8) Peer-ReviewedUnderstanding spontaneous imbibition helps to determine the fracturing fluid volume and optimize the flowback design. At present, many studies have mainly focused on shale, but few on igneous rocks. As such, in this...
- 2From:Mathematical Problems in Engineering (Vol. 2021) Peer-ReviewedIt is difficult to determine the safe operation window of drilling fluid density (SOWDFD) for deep igneous rock strata. Although the formation three-pressure (pore pressure, collapse pressure, and fracture pressure)...
- 3From:Atlantic Geoscience (Vol. 58) Peer-ReviewedThe island of Bermuda is unique because its geology is inconsistent with established theories on the formation of volcanic seamounts. Research into the formation of the Bermuda rise began in the early 20th century with...
- 4From:Glass and Ceramics (Vol. 78, Issue 7-8) Peer-ReviewedCriteria were studied and experimentally confirmed for achieving a synergistic effect for optimizing and controlling the process of obtaining heat-insulating porous materials using the igneous rocks of the crystalline...
- 5From:Journal of Open Research Software (Vol. 9, Issue 7) Peer-ReviewedFastGAPP (Fast Geoscientific Analyses Plotting Program) is a MATLAB-based graphical user interface. It is developed to quickly explore and interpret geochemical major and trace element analyses of igneous rocks in over...
- 6From:Doklady Earth Sciences (Vol. 495, Issue 2) Peer-ReviewedOxidation decomposition of titanomagnetite grains to the magnetite-ilmenite lattice during the formation of igneous rock can lead to thermochemical remanent magnetization (TCRM). Computer simulation of TCRM in the...
- 7From:Contributions to Mineralogy and Petrology (Vol. 177, Issue 3) Peer-ReviewedHow and what extent residual garnet in the source and garnet fractionation contribute to the heavy Fe isotopic compositions in high-silica igneous rocks remain unexplored. We here measured the Fe isotopic compositions of...
- 8From:Glass and Ceramics (Vol. 78, Issue 9-10) Peer-ReviewedA method of producing ceramics from igneous rocks is presented for the example of gabbro. It is shown that potassium liquid glass can be used as a binder. The method of physicochemical modeling was used to calculate the...
- 9From:Sustainability (Vol. 15, Issue 5) Peer-ReviewedAluminum is globally the most used nonferrous metal. Clarifying the consumption of primary aluminum is vital to economic development and emission reduction. Based on the signal decomposition tool and S-curve model, a new...
- 10From:Geochemistry International (Vol. 58, Issue 12) Peer-ReviewedAbstract- The paper presents experimental data on fluorine leaching from igneous rocks (dacite, rhyodacite, and trachyrhyolite) and greisen with distilled water and 0.01 M HCl, CH.sub.3COONa, NaHCO.sub.3, and...
- 11From:Chemical EngineeringPeer-ReviewedFlyash, a waste byproduct from coal burning, has been used effectively as a supplementary cementitious material (SCM) in Portland cement to displace a portion of the cement and lower the CO 2 emissions associated with...
- 12From:Earth Surface Dynamics (Vol. 10, Issue 3) Peer-ReviewedThe denudation of rocks in mountain belts exposes a range of fresh minerals to the surface of the Earth that are chemically weathered by acidic and oxygenated fluids. The impact of the resulting coupling between...
- 13From:Shock and Vibration (Vol. 2018) Peer-ReviewedThe uniaxial cyclic loading tests have been conducted to study the mechanical behavior of dry and water saturated igneous rock with acoustic emission (AE) monitoring. The igneous rock samples are dried, naturally...
- 14From:Soil (Vol. 6, Issue 1) Peer-ReviewedRecent studies indicate that climate change influences soil mineralogy by altering weathering processes and thus impacts soil aggregation and organic carbon (SOC) stability. Alpine ecosystems of the Neotropical Andes are...
- 15From:Atlantic Geoscience (Vol. 58) Peer-ReviewedThe Castle Frederick prospect is a Pb-Zn play hosted in the granitoid rocks of the Late Devonian (~380-365 Ma) South Mountain Batholith (SMB), within the Meguma terrane, near Upper Falmouth, Nova Scotia. The geochemical...
- 16From:Progress in Earth and Planetary Science (Vol. 9, Issue 1) Peer-Reviewed
From desert to monsoon: irreversible climatic transition at ~ 36 Ma in southeastern Tibetan Plateau.
Although there is increasing evidence for wet, monsoonal conditions in Southeast Asia during the late Eocene, it has not been clear when this environment became established. Cenozoic sedimentary sequences constrained by... - 17From:Journal of Medical Evidence (Vol. 3, Issue 1) Peer-ReviewedByline: Shibu. Sasidharan, Harpreet. Dhillon Mt. Nyiragongo in Goma, DR Congo, exploded on 22 May 2022. In the Philippines, on 1 July 2021, the Taal volcano, considered a restive volcano, spewed a 0.62 mile-high plume...
- 18From:International Journal of Coal Science & Technology (Vol. 8, Issue 1) Peer-ReviewedMesozoic and Cenozoic magma activity in the Wolong Lake mining area of Huaibei is frequent, and the degree of magma intrusion into coal seams remarkable. On the one hand, magma intrusion affects the utilization of coal...
- 19From:Doklady Earth Sciences (Vol. 492, Issue 2) Peer-ReviewedThe results of isotope-geochronological study of Quaternary mafic volcanism in the Kapan neovolcanic center (Southern Armenia) are discussed. The rocks studied are represented by alkaline basaltoids with haüyne as the...
- 20From:Journal of Radioanalytical and Nuclear Chemistry (Vol. 327, Issue 3) Peer-ReviewedInstrumental neutron activation analysis is applied for the determination of 28 chemical element concentrations in seven geological reference materials (USGS), namely CMP-1, COQ-1, NKT-1, SyMP-1, G-3, SSAR-1, and SBC-1....
