PREFACE In the study of sediments and sedimentary basins, subsidence analysis provides an essential step to understand basin evolution through geologic time and space. Quan-tifying techniques have been developed and applied in many basin research projects to evaluate total, tectonic and thermal subsidence, used also as a pre-requisite for basin mod...

The Naturaliste Plateau is a submarine continental ribbon rifted from the southwest Australian margin during the Early Cretaceous breakup of East Gondwana. It occupied a key position near the juncture of Greater India and the boundary between Australia and Antarctica. However, details of the Early Cretaceous evolution of the plateau are not well kn...

In this paper, we describe porosity variations in Miocene to Holocene carbonates off the west coast of Australia and assess their compaction trends. The porosity values were measured using discrete samples of Sites U1459–U1464 obtained by the International Ocean Discovery Program Expedition 356. The carbonate deposits have been influenced by a rang...

Petrophysical properties of volcanic rocks are controlled by lithology and subsequent modification by alteration processes. Investigating the linkages, using a range of different techniques, are important to establish how petrophysical properties can inform about the alteration state of volcanic rocks. Here, we compile petrophysical data and correl...

International Ocean Discovery Program Expedition 369 drilled four sites on the southwestern Australian continental margin, in the deep water Mentelle Basin (MB) and on the neighboring Naturaliste Plateau (NP). The drillsites are located on continental crust that continued rifting after seafloor spreading began further north on the Perth Abyssal Pla...

Sedimentation impacts thermal and subsidence evolution in continental rifting. Estimating the blanketing effect of sediments is crucial to reconstructing the heat flow during rifting. The sedimentary load affects the basin subsidence rate. Numerical investigation of these effects requires active and complex simulations of the thermal structure, lit...

The Upper Cretaceous sedimentary sequence at International Ocean Discovery Program Site U1512 in the Ceduna Sub-basin of the Great Australian Bight represents a continuous, > 690 m thick interval of black silty clay and claystone spanning the lower Turonian through Lower Campanian (~10 million years).

The Mentelle Basin, located off the southwestern continental Australian margin, is an underexplored deep-water basin that developed during the breakup of eastern Gondwana in the Middle Jurassic through to the Early Cretaceous. There is a high degree of uncertainty in stratigraphic interpretations of the basin owing to the lack of well and seismic d...

Detrital heavy mineral analysis and sediment chemistry of Lower Miocene sediments of the Lower Austrian Northern Alpine Foreland Basin generally indicate provenance from metapelitic source rocks. The sediments of the Traisen Formation (Ottnangian) were primarily derived from Alpine sources such as the Austroalpine crystalline units of the Eastern A...

Western Australia is bordered by a rifted continental margin formed during opening of the East Indian Ocean in Late Jurassic through Early Cretaceous time as Greater India rotated counterclockwise away from Australia and Antarctica during the breakup of East Gondwana.

The Perth Basin is a large (c. 172,300 km2) north-south elongated sedimentary basin extending offshore and onshore for about 1,300 km along the southwestern continental margin of Australia. It is a relatively under-explored region, despite being an established hydrocarbon producing basin whose hydrocarbon potential has proven over the basin area. T...

This chapter introduces three subsidence analysis models which are total subsidence, tectonic subsidence and post-rift thermal subsidence. The three subsidence models are essential to understand evolution of a sedimentary basin. Due to compaction effect, the present stratigraphic framework of a sedimentary basin fill does not present directly the p...

In this chapter, we introduce geological data visualization techniques and discuss how these techniques can be applied to the subsidence analysis and visualization of a sedimentary basin. Geoscientific data are often sparsely distributed over wide study areas, therefore data interpolation is required to generate comprehensive maps. We examine five...

Basin analysis is a research field to understand the formation and evolution of sedimentary basins. This task requires various geoscientific datasets as well as numerical and graphical modelling techniques to synthesize results dimensionally in time and space. For basin analysis and modelling in a comprehensive workflow, BasinVis 1.0 was released a...

To understand the formation and evolution of a sedimentary basin in basin analysis and modelling studies, it is important to analyze the thickness and age range of sedimentary layers infilling a basin. Because the compaction effect reduces the thickness of sedimentary layers during burial, basin modelling studies typically restore the reduced thick...

The Mentelle Basin (MB) and Naturaliste Plateau (NP) at the southwestern margin of Australia hold important information for understanding the tectonic events, volcanism and paleo-environmental changes at different stages of the Gondwana breakup between Australia, Antarctic and India. The SW Australia region is characterized by the distribution of o...

The Mentelle Basin (MB) is part of an extensional rift system on the western margin of Australia and formed during the Paleozoic to Mesozoic breakup of eastern Gondwana. The MB has a complex evolution history of rifting, volcanism and sedimentation related to tectonic events, paleoclimate and paleoenvironmental changes. IODP Expedition 369 generate...

In subsidence analysis of a sedimentary basin, it is necessary to use an appropriate porosity-depth curve, because understanding the relationship between porosity and burial depth is crucial for decompaction and backstripping techniques to calculate the original thickness of a sediment unit. The relationship is controlled by a variety of factors in...

The tectonic and paleoceanographic setting of the Great Australian Bight (GAB) and the Mentelle Basin (MB; adjacent to Naturaliste Plateau) offered an outstanding opportunity to investigate Cretaceous and Cenozoic climate change and ocean dynamics during the last phase of breakup among remnant Gondwana continents. Sediment recovered from sites in b...

Late Miocene to mid-Pleistocene sedimentary proxy records reveal that northwest Australia underwent an abrupt transition from dry to humid climate conditions at 5.5 million years (Ma), likely receiving year-round rainfall, but after ~3.3 Ma, climate shifted towards an increasingly seasonal precipitation regime. The progressive constriction of the I...

Global climate underwent a major reorganization when the Antarctic ice sheet expanded ~14 million years ago (Ma) (1). This event affected global atmospheric circulation, including the strength and position of the westerlies and the Intertropical Convergence Zone (ITCZ), and, therefore, precipitation patterns (2–5). We present new shallow-marine sed...

The northwest shelf (NWS) of Australia extends from northern tropical to southern temperate latitudes situated offshore from the low-moderate-relief and semi-arid Australian continent. The shelf environment is dominated throughout by carbonate sedimentation with warm-water and tropical carbonate deposits, connected to the long-term northward drift...

Porosity in sediments is influenced by various factors such as mineralogical composition, burial depth, connate fluids, and stratigraphic layering. This work focuses on processes underlying porosity anomalies in carbonate shelf deposits along the northwest shelf of Australia by using different techniques (polarization microscopy, electron microscop...

The Vienna Basin is a tectonically complex Neogene basin situated at the Alpine–Carpathian transition.
