The contribution to Tethyan and global Triassic studies from the Australian sector of southeastern Tethys is limited relative that Himalayan sector. Whilst many successions are located offshore, one succession exposed on island Timor. This marine succession, dismembered during collision between continent Sundaland, has been investigated for over 100 years but also made modern contributions studies. To address this a new integrated biostratigraphic microfossil database (conodonts,...
In East Timor the upper parts of Permian to Middle Jurassic Gondwana Megasequence are structurally juxtaposed against indurated carbonate pelagites Early Cretaceous (Aptian) early Late Miocene age. The probably represent a thin (several hundred metres thick) succession that was deposited at middle lower bathyal water depths unconformably above after continental breakup. widespread occurrence pelagites, lack turbidites least in post-Albian succession, association with and Upper shales...
ABSTRACT Variostomatids from Late Triassic basinal facies in Timor-Leste include a new genus, Pualacana n. gen. with P. hortai sp. as type species. It is separated Variostoma Kristan-Tollmann by absence of the large spinose projections on chambers that characterize V. spinosum Kristan-Tollmann, species Variostoma, and duostominids having umbilicus covered overlap final twisted chamber arrangement about slightly variable test axis. includes many formerly included Variostoma. Six are...

An uppermost Gzhelian bioherm discovered in the central highlands of Timor Leste contains abundant foraminifera belonging to 17 genera. Representatives families Biseriamminidae, Biwaellidae, Bradyinidae, Cornuspiridae, Lasiodiscidae, Palaeotextulariidae, Pseudotaxidae, Ozawainellidae, Schubertellidae, Schwagerinidae, Staffellidae and Textrataxidae are present, including 21 species referred known types 12 left open nomenclature. Two new Schwagerina described: timorensis species, maubissensis...
Timor lies at the centre of a rapidly evolving orogenic belt. The Matebian Range, one its largest mountains, was previously mapped as Lower Miocene neritic Cablac Limestone and regarded allochthonous (namely, Banda Terrane). New analyses have demonstrated disjunct stratigraphy, extending from Jurassic to lowest encompassing abyssal strata. Positioning each stratigraphic unit (six new) on time v. bathymetry plot identifying clast types in conglomerates turbidites allows reconstruction changes...
Ammonoid-rich wackestone beds forming a ca 2 m section between shallow-marine limestones of the Bandeira Group (Norian to possibly Rhaetian) and wackestone–calcareous mudstone succession belonging Lower Jurassic Wailuli are recorded from western part Timor Leste. They included in Halstätt-like Lilu Facies Group. Age-diagnostic involutinid foraminiferal species, not previously Timor, include Involutina liassica, Trocholina sp. ex. gr. turris Lamelliconus permodiscoides, which collectively...
SummaryThe logging and biostratigraphic characterization of the Foura Sandstone type section, Timor-Leste, show it is Carnian–early Norian (Samaropollenites speciosus Zone). Sedimentary structures indicate a turbidite origin petrographic analysis reveals high proportion volcanic lithic grains.Palynological material presents variable preservation suggesting complex pre-burial history involving longdistance transport. The presence prasinophytes suggests anoxic euxinic depositional settings.
Stratigraphic units, characterized by distinct rock types, ages and depositional environments, are described from one of the most geologically chaotic terranes on present-day western Australian continental margin. The Matebian Overthrust Terrane in Timor-Leste has components interpreted to have been deposited (1) Early Jurassic northern margin eastern Gondwana; (2) off Late Cretaceous southern Sundaland south-east Asia, probably vicinity east Java–south Sulawesi; (3) an Eocene earliest...
A palynological analysis of the basinal volcaniclastic turbiditic Foura Sandstone Member within Babulu Formation in Timor-Leste reveals rich assemblages including well-preserved material that correlates with upper Ladinian–Carnian Staurosaccites quadrifidus–?lower Samaropollenites speciosus spore-pollen zones Australia. The high diversity conifer pollen these indicates an association microfloras western (Argentina) and eastern Gondwana (west Australia India) form Onslow paleobiogeographic...
