Publisher : Geological Agency

DOI:Â 10.17014/ijog.v5i1.91The interregional and global correlation of the Triassic biota of Indonesia was based on the review of previous workers and the author himself. Scythian Epoch (Early Triassic) in Timor is subdivided into Early Scythian with Ophiceras demisso, Meekoceras sp., Pseudomonotis subaurita, Gervillia subpannonica, and Myophoria sp., whilst Late Scythian is indicated by the presence of Owenites egrediens and Sibirites sp. The presence of Anisian Stage (Middle Triassic) in Misool is indicated by ammonite Beyrichites and bivalve Daonella lilintana. In Timor, this stage is pointed out by the presence of Joannites cymbiformis, Monophyllites wengensis, Protrachyceras archaelus, Daonella indica, Tracyceras cf. aon, Brochidium timorense, and Lima subpunctatoides. Terebellina mackayi found above Beyrichites-bearing bed in Misool has an age range from Anisian to Ladinian. It is concluded that the boundary between Anisian and Ladinian lies between beds with Beyrichites and Terebellina mackayi. Early Carnian Stage (Late Triassic) in Timor is indicated by the presence of Joanites cymbiformis, Waldhausenites sp., Miltites sp., and Halogyra cipitiensis; whereas Late Carnian is indicated by the presence of Cladicites crassestriatus and Tropites subbulatus. The presence of Halobia verbeeki, Pinacoceras parma, Neobetites sp., Parabetites sp., Malayites sp., Amarassites sp., and Halorites sp., indicates the Early Norian Stage, whilst the presence of Cladiscites tornatus, Cyrtopleurits malayicus, and Trachypleuraspidites sp. implies the Late Norian. The Rhaetian Stage in Timor contains Choristoceras indoaustralicum, whereas in Misool it contains Choristoceras sp. and Cochloceras sp.

Cretaceous rocks of Misool Archipelago are exposed mostly on the southern part of the main island of Misool and its adjacent islets. The rocks belong to the upper part of Lelinta Formation, Facet Limestone Group (Waaf Formation and Gamta Formation), Fafanlap Formation (Yabatano Member) and lower part of Daram Formation. The age of the rocks ranges from Aptian to Maastrichtian based on their fossil content. The lithology of each formation is redescribed herein.The results show that almost the whole formations contain macrofossils such as molluscs and microfossils (foraminifera). The Gamta Formation (the oldest) is Late Berriasian to Middle Cenomanian in age based on the occurrences of Ptilorhynchia sp., Proclydonophora sp., Rotularia sp., Buchia sp .. ammonite gen. et sp. indet, coral indet., and trace fossils. Early Cretaceous is also indicated by the presence of Hibolithes gamtaensls, H. miosensis, Duvalia spp., and Belemnopsis jonkeri. Waaf Formation (Middle Cenomanian to Early Campanian) contains rich globigerinid and other microfossils, trace fossils, large Inoceramus up to 70 cm in length with oysters attached to it, and Prochlydonophora sp. But, this bivalve is very difficult to sample. The upper part of the Waaf Formation oontains abundant microfossils, probably indicating a bathyal environmenl Fafanlap Formation and its Yabatano Member contain micro and macrofossils such as Inoceramus misoliensis, I. (Cordiceramus} paraheberti, I. (C.) cf. pseudoregularis, t. (Selenoceramus) sufflatus and t.haani, Durania wanneri, and burrows indet. Micraster and Hemiaster were difficult to sample, and so were minor coral and bryozoan. lnoceramus spp. which are found in the lower part of Fafanlap Formation indicate a Middle Campanian age. The microfossils range up to Maastrichtian. It can be concluded that the age of Fafanlap Formation is Late Santonian up to late Maastrichtian and at least Late Maastrichtian for the Yabatano Member. Based on the assemblage of microfossils reported by previous workers, the age of the Daram Formation in the tower part can be assumed as Late Maastrichtian.Biostratigraphic correlation of Lower Cretaceous in Indonesian Archipelago based on microfossils promising for the islands of Rote, Timor, Seram, Buru, Buton, the eastern, central and south arms of Sulawesi, Halmahera, New Guinea and perhaps Obi and eastern Kalimantan. In the upper Cretaceous, inooeramid bivalves are more common and are closely related to those of New Guinea and Madagascar.Cretaceous of the Misool Archiprelago is the most difficult part to correlate within Indonesia based on microfossils at present, but is promising in the future study. The microfauna of Misool is closely related to that of the Emscher Marl of Westfalen In Europe. Theforaminifera also resemble those of theSeweer Beds in the European Alps. The Easy Cretaceous of the upper part of the lochambel Beds of Spiti, India with the Neocosmoceras-Distoloceras Assemblage is probably correlatable with the upper part of the lelinta Formation of Misool. In Misool, however the latter is dominated bybelemnites even though similar in rock facies (chert-bearing beds). The inoceramid species trom Misool, e.g. lnoceramuscf. bererensis, I. (Cordiceramus) paraheberti and I, (C.} cf. pseudoregularis are closely similar to those found inMadagascar, some perhaps beingcoospecific, and in both area indicating a Middle Campanian age.Keywords: Misool Archipelago,Cretaceous, Lelinta Formation, Gamta Formation,Waaf Formation, Fafanlap Formation, D aram Formation, inoceramids, belemniles, foraminifera

Terebellina mackayi is an annelid fossil species which forms a tubular agglutinated body. It is a Middle Triassic taxon which has a common distribution in the world and has been recorded from Sumatera, Thailand, Misool, Timor, and New Zealand. A collection of small sized specimens of the species from the Keskain Formation (Misool) of Anisian to Ladinian age is here redescribed and a global correlation is attempted. Terebellina mackayi is commonly found in a random orientation of distribution within beds. The organism which is constructed of tubular shape remains enigmatic but was probably suspension feeder rather than browser, deposit feeder or active predator. Terebellina mackayi lived in a fine grained black silt substrate (infauna) rich in organic detritus. Keywords: Keskain Formation, Annelid, Terebellina mackayi, Anisian, Ladinian

The known gastropod fauna of Triassic and Jurassic ages from the Misool Archipelago is reviewed, based on collections made during a 1981 expedition jointly by personnel from the then-Geological Research and Development Centre, Bandung, and the Australian Bureau of Mineral Resources. The new material includes one new species, Bathrotomaria foronica, from the Yefbie Formation (Aalenian), and two undescribed but probably new species, a Rhaetian ?Angularia from the Lios Member of the Bogal Formation and a Purpurina of Aalenian or jBajocian age from the Yefbie Formation. In addition, other material from the Rhaetian Lios Member, too poorly preserved for generic identification, is allotted to the Subfamily Neritinae. Some forms recorded by earlier workers were not recollected but have been listed for completeness, giving a total of five described species and a further five in open nomenclature. Most taxa are unique to this area, but one, Eucyclus orbignyanus (Hudleston), is known also from Europe.

A biostratigraphic study in Rote Island has proven that the distribution of Mesozoic rocks (especially Triassic, Jurassic,and Cretaceous) are broader than was thought by previous workers. The Paleozoic rocks are not exposed, but somefossils collected from the surface suggest that such rocks are present deep down in the earth subsurface of this island.The fossils were brought to the surface along with other materials by mud volcanoes which are common on the island.Mesozoic biostratigraphy of the Rote Island begins with Triassic, followed by Jurassic up to Cretaceous which areindicated by the presence of its fossils. Timorites sp., an ammonite genus indicating Permian (Paleozoic), yet theformation from which it originated is not known.In Mesozoic time, some species of Halobia lived indicating a Carnian to Early Norian age as shown by the presence of H.(H.) austriaca, H. (H.) styriaca, and H. (H.) charlyana in the Aitutu Formation. The presence of Monotis (M.) salinariashows that the Aitutu Formation is up to Late Norian in age. Fossil association is found in the Wailuli Formation,consisting amongst others of Ostrea sp., Perisphinctes timorense, Belemnopsis moluccana, B. galoi, B. stolleyi,Orbyrhynchia sp. and Irianites sp. Irianites sp. which indicates Bathonian is also found in the coeval formation in SulaIslands. Perisphinctes is generally found in Late Oxfordian. Belemnopsis moluccana has an age range from EarlyOxfordian to Early Tithonian, B. galoi from Kimmeridgian to Late Tithonian, and B. Stolleyi from Early Tithonian toBerriasian.The Nakfunu Formation exposed in Termanu area has a Cretaceous age in Rote Island. The formation is rich in radiolariasuch as Dictyomitra sp. which indicates Albian (Early Cretaceous). Trace fossils such as a large paramoudra are alsofound. Samples of radiolaria-bearing rocks were also collected, but the materials have not been studied due to lack ofthe expertise in the Geological Survey Institute.

The Jurassic fauna of Misool Archipelago is very similar to Sula Islands on the basis of bivalve content, but it differs from Sula Islands in that good ammonite assemblages which replaced by assemblages of belemnites. The fauna of Misool Archipelago can also be correlated with Papua is on the basis of ammonite fauna such as Fontannesia killiani. Misool Archipelago fauna is also correlable with those of the European Alps, North America, Chile, Argentina, New Zealand, Northwestern Australia, North and South Tibet, Himalaya, etc. However, some areas correlation is based only on a few species and sometimes only on cosmopolitan genera. Keywords: Jurassic, Misool Archipelago, ammonites, bivalve, interregional and global correlation

The Early Miocene Pakaurangi Formation, Waitakere Group, have a high diversity of Ostracoda. Key species include Loxoconcha propunctata, Bradleya semiarata, Bradleya lactea pakaurangia, Hemycythere tarakohensis and Bairdia canterburyensis, and indicate an Altonian age, completely in agreement with foraminiferal ages from this area by other workers.The species Trachyleberis zeacristata Hornibrook is transferred to Henryhowella. Paijenborchella iocosa Kingma, and many generic level taxa were also found in a borehole in Bojonegoro, East Jawa, Indonesia. The previously recorded Clifdenian to Waitotaran range of Henryhowella probesioides Hornibrook is extended downwards into the Altonian. The Ostracoda also show the paleoenvironment of the Pakaurangi Formation to be littoral to neritic, which is also in agreement with the evidence of foraminifera and molluscs as reported by previous workers. Keywords: Ostracoda, Pakaurangi Formation, Waitakere Group, Altonian, New Zealand

A geological and paleontological studies on the Balangbaru and Marada Formations has been carried out. Both formations show that their depositional environment was in basin with turbidity currents. Marada Formation can be correlated with Panggalungan Member of the distal part of the Balangbaru Formation. Paleontological study on the Balangbaru Formation has yielded some macrofossils such as echinoid, bivalve Inoceramus sp., ammonite Grossouvreites sp. Marada Formation contains trace fossil Spirorhaphe sp. and species of nannoplankton have been extracted from the shale e.g. Ceratolithoides aculeus, C. kamptneri, Lucianorhabdus cayeuxii, L. arcuatus, L. maleformis, Micula murus, M. concava Lithraphidites quadratus, and Prediscosphaera sp. Based on the presence of macrofossils, nannoplankton, and radiolarian fossils of previous workers it can be concluded that the deposition of the Balangbaru and Marada Formations was in Albian to Maastrichtian (Late Early Cretaceous to Late Cretaceous) time. Keywords: echinoid, bivalvia, ammonite, trace fossil, nannoplankton, radiolarian turbidite

The study of molluscs from the Malawa Formation revealed the paleoenvironmental deposition of the formation. Four measured stratigraphic sections which are representastive of the formation contain well preserved molluscan fauna. The results of analysis indicate that the Malawa Formation of Middle Eocene age has been deposited in a mangrove environment, near shore, high energy, with fresh water influx such as rivers, in a lagoon with sand bars, a kind of deltaic environment. Keywords: Malawa Formation, Middle Eocene, molluscs, mangrove, deltaic environment
