The Antarctic Ross and the Australian Delamerian orogenies are consequence of stress transfer to outboard trailing edge newly assembled Gondwana supercontinent. This tectonic reorganization occurred in Early Middle Cambrian on completion Pan‐African deformation subduction along sutures between eastern western Gondwanan continental fragments. Before this, Neoproterozoic rocks Australia were formed a passive margin record dispersion Rodinia with consequent opening proto‐Pacific. Our new U‐Pb...
Multimethod chronology was applied on intrusives bordering the Kyrgyz South Tien Shan suture (STSs) to decipher timing of (1) formation and amalgamation suturing units (2) intracontinental deformation that built mountain ranges. Zircon U/Pb data indicate similarities between Tarim Precambrian crust. Caledonian (∼440–410 Ma) Hercynian (∼310–280 zircon ages were found at edge STSs, related subduction closure Turkestan Ocean itself. Permian‐Triassic (∼280–210 titanite fission track (U‐Th)/He...

The distribution pattern of U-Pb ages detrital zircon in a sedimentary rock is commonly assumed to reflect the igneous or metamorphic processes rocks that have contributed material basin (i.e. protosources), directly through recycling older rocks. If Pb isotopic composition modified by after crystallization, influenced unintended effects data treatment such as discordance filters and common lead correction, value geological indicator compromised. Discordance will identify zircons having...
Abstract The development of fast and reliable instrumental methods for U‐Pb dating Lu‐Hf isotope analysis zircon has caused detrital to become a popular provenance indicator clastic sediments an important tool in basin analysis. In parallel with the increasing ease access data, advanced data interpretation have been developed. downside some techniques visualization comparison distribution patterns is that results are difficult relate what grains really record: age nature geological processes...
In the South Australian sector of Cambro-Ordovician Ross–Delamerian Orogen, granites range in age from Mid-Cambrian to Early Ordovician. Their occurrence is largely confined deep, Cambrian, sediment-filled basins where they are associated with mafic rocks. The syntectonic suites have compositions forming a continuum between I- and S-type granites. After cessation convergent deformation at c . 490 Ma an abrupt transition bimodal magmatic association intrusions felsic volcanic rocks S- A-type...
U-series isotopes can provide unique insights into the physical processes of magma evolution by constraining time scales over which they operate. This, however, requires rock suites that a clear and complete record liquid line descent. Sangeang Api volcano, in east Sunda arc, provides such an opportunity because it erupts potassic lavas (SiO2 ∼ 47–55%), contain spectrum xenoliths interpreted to represent cumulates complementary lavas. Combined, span large compositional range, major trace...
