Zircon energy Antarctica

A large-scale transcontinental river system crossed West Antarctica

Major Antarctic glaciation initiated at the Eocene-Oligocene transition ~34 million years ago (Ma), marking one of the most pronounced climate transitions of Phanerozoic times ().The reconstruction of Antarctica''s paleoenvironmental and paleotectonic conditions before this transition, i.e., in the middle to late Eocene, provides important boundary conditions for

Age provinces in the Antarctic craton: Evidence from detrital zircons

Detrital zircon studies on upper Neoproterozoic and Cambrian strata in the same region (Goodge et al., 2002, Goodge et al., 2004b) have provided data on age provinces eroded at that time.Additionally, studies on metamorphic and igneous clasts in modern glacial tills, collected from CTM, and derived from the craton have provided further data on sub-glacial

Renewable energy

Transporting fuel and oil to Antarctica is a costly and sometimes risky exercise. Before the introduction of renewable energy systems, Australian stations required 2.1 megalitres of diesel fuel every year for power and heating. Burning this fuel emitted around 5,500 tonnes of carbon dioxide into the Antarctic environment.

Detrital zircon ages and trace element compositions of Permian–Triassic

Detrital zircon U-Pb and trace element data provide new information on the provenance of Permian–Triassic foreland basin deposits of the Gondwanide orogen that belong to the Beacon Supergroup in Antarctica. Zircon U/Th ratios primarily point to dominantly igneous parent rocks with subordinate contributions from metamorphic sources.

Zircon, a highly refractory mineral, can survive in a variety of magmatic, metamorphic, and sedimentary environments. As a result, it plays a pivotal role in elucidating the origin of geological features and the evolution of the Earth''s crust (Belousova et al., 2010).Generally, zircon crystals incorporated from the surrounding host rocks during magma

Thermal History of UHT Metamorphism in the Napier

High-grade gneisses from Mt. Riiser-Larsen, East Antarctica, have been dated by whole-rock-mineral Sm-Nd and SHRIMP zircon and monazite U-Pb to help deﬁne the thermal history of ultrahigh temperature (UHT)metamorphism in the Napier Complex. Both the monazite and youngest zircon yield a range of apparent ages (∼2.51–2.47 Ga),

Interpretation of discordant U-Pb zircon ages: An evaluation

Pb-diffusion in the pristine zircon lattice is insignificant up to temperatures of at least 1000 °C. Pb-loss is only possible if the zircons experienced a time interval below their annealing temperature of about 600–650 °C, because only below this temperature can the lattice damage through α-decay and spontaneous fission accumulate.

6 FAQs about [Zircon energy Antarctica]

Are there detrital zircon ages and trace element compositions in Antarctica?

New detrital zircon age and trace element evidence for 1450 Ma igneous zircon sources in East Antarctica. Precambrian Res. 300, 53–58 (2017). Paulsen, T. et al. Detrital zircon ages and trace element compositions of Permian–Triassic foreland basin strata of the Gondwanide orogen, Antarctica. Geosphere 13, 1–9 (2017).

How many detrital zircons are there in Antarctica?

We carried out a coupled U–Pb age and trace element analysis of 5,715 detrital zircons from 46 sandstone samples (primarily Neoproterozoic–early Palaeozoic in age) widely distributed along a ~3,000-km-long swath of the Neoproterozoic–early Palaeozoic Pacific-Gondwana margin in Antarctica (Fig. 1 and Supplementary Fig. 1 ).

What is a detrital zircon U-Pb & trace element?

How is zircon ablated?

The analyses involve ablation of zircon with a 193 nm ASI Resolution 155 ArF excimer laser using a spot diameter of 29 µm, under a 100% He atmosphere. The ablated material is carried by an He-Ar mixture to the plasma source of a Thermo Element XR magnetic sector ICP-MS equipped with a triple detector (pulse counter, analogue and Faraday cup).

Where did the zircon age come from?

The sources of this zircon age population may include exposed and ice-covered igneous provinces in Antarctica, such as the Ross orogen 18, 19, 20, for example, as well as interior areas of Gondwana such as the East African orogen 21.

Do igneous zircons have trace elements?

Trace elements were measured using the same LA-ICP-MS instrument in an effort to determine the source rock provenance of the igneous zircons. Laser spots typically reoccupied the same spot location for the U–Pb age analyses for the majority of the new data reported here.
