Neoarchean Arc Magmatism and Crust Recycling in the Northern Marginal Zone of the Limpopo Complex, Zimbabwe: New Insights From Zircon U‐Pb‐Hf Isotopes of a Charnockite Suite

open access: yesGeological Journal, EarlyView.
Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

Geochronology and geochemistry of the Fogang granitic batholith and its implications for uranium mineralization

open access: yesFrontiers in Earth Science
The E–W-striking Fogang granitic batholith represents the largest composite batholith in Guangdong Province. To date, the only known uranium deposit, the Pajiang deposit, has been identified in the southwestern portion of the Fogang granitic batholith ...

Theory of Time-Temperature-Stress Equivalent Principle Based on Schapery Equation and Its Application on Granite

open access: yesMedžiagotyra, 2014
The time-temperature-stress equivalent (TTSE) principle refers to the phenomenon that the time-dependent mechanical properties of materials rely on the variations of temperature and stress level.

Preliminary report on the geology and gold mineralization of the South Pass granite-greenstone terrain, Wind River Mountains, western Wyoming (US) [PDF]

open access: yes
The South Pass granite-greenstone terrain lies near the southern tip of the Wind River Mountains of western Wyoming. This Archean supracrustal pile has been Wyoming's most prolific source of gold and iron ore. From 1962 to 1983, more than 90 million tons

Effect of Elevated Temperature on Mechanical Properties of Limestone, Quartzite and Granite Concrete

open access: yesInternational Journal of Concrete Structures and Materials, 2016
Although concrete is a noncombustible material, high temperatures such as those experienced during a fire have a negative effect on the mechanical properties.

High‐Titanium Zircon Rims in Rhyolite – A Reflection of Adiabatic Ascent?

open access: yesGeological Journal, EarlyView.
The ascent of granitic magma from source to emplacement is rapidly achieved through dyking, resulting in negligible heat loss to the surrounding wallrock (i.e., adiabatic). Zircon growth during ascent can record the changing magma conditions including adiabatic cooling and heating, resulting in high titanium rims on low titanium cores without ...

Spalling characteristics of high-temperature treated granitic rock at different strain rates

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
The dynamic spalling characteristics of rock are important for stability analysis in rock engineering. This paper presented an experimental investigation on the dynamic spalling characteristics of granite with different temperatures and strain rates.

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China

open access: yesGeological Journal, EarlyView.
Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.
