	<strong>Abstract</strong><br/ >
	It is well documented that the Cenozoic progressive flooding of Australia, 
	contemporaneous with a eustatic sea level fall, requires a downward tilting 
	of the Australian Plate towards the SE Asian subduction system. Previously, 
	this large-scale, mantle-convection driven dynamic topography effect has 
	been approximated by computing the time-dependent vertical shifts and 
	tilts of a plane, but the observed subsidence and uplift anomalies 
	indicate a more complex interplay between time-dependent mantle convection 
	and plate motion.  We combine plate kinematics with a global mantle 
	backward-advection model based on shear-wave mantle tomography, 
	paleogeographic data, eustatic sea level estimates and basin stratigraphy 
	to reconstruct the Australian flooding history for the last 70 Myrs on a 
	continental scale. We compute time-dependent dynamic surface topography 
	and continental inundation of a digital elevation model adjusted for 
	sediment accumulation. Our model reveals two evolving dynamic topography 
	lows, over which the Australian plate has progressively moved. We 
	interpret the southern low to be caused by sinking slab material  with an 
	origin along the eastern Gondwana subduction zone in the Cretaceous, 
	whereas the northern low, which first straddles northern Australia in the 
	Oligocene, is mainly attributable to material subducted north and northeast 
	of Australia. Our model accounts for the Paleogene exposure of the Gulf of 
	Carpentaria region at a time when sea level was much higher than today, 
	and explains anomalous Late Tertiary subsidence on Australia's northern, 
	western and southern margins.  The resolution of our model, which excludes 
	short-wavelength mantle density anomalies and is restricted to depths 
	larger than 200 km, is not sufficient to model the two well recorded 
	episodes of major transgressions in South Australia in the Eocene and 
	Miocene.  However, the overall, long-wavelength spatio-temporal pattern of 
	Australia's inundation record is well captured by combining our modelled 
	dynamic topography with a recent eustatic sea level curve.  We suggest 
	that the apparent  Late Cenozoic northward tilting of Australia was a 
	stepwise function of South Australia first moving away northwards from the 
	Gondwana subduction-related dynamic topography low in the Oligocene, now 
	found under the Australian-Antarctic Discordance, followed by a drawing 
	down of northern Australia as it overrode a slab burial ground now 
	underlying much of the northern half of Australia, starting in the 
	Miocene. Our model suggests that today's geography of Australia is 
	strongly dependent on mantle forces.  Without mantle convection, which 
	draws Australia down by up to 300 m, nearly all of Australia's continental 
	shelves would be exposed.  We conclude that dissecting the interplay 
	between eustasy and mantle-driven dynamic topography is critical for 
	understanding hinterland uplift, basin subsidence, the formation and 
	destruction of shallow epeiric seas and their facies distribution, but 
	also for the evolution of petroleum systems.

	Here's a new version of the reconstructed Australian paleogeography
	for the last 70 Ma. The model combines mantle-induced dynamic topography,
	eustatic sealevel changes (Haq &amp; El-Qhatani, 2005) and account for 
	sedimentation by backstripping. More details follow soon.

  <title>How to build GPlates on Mac OS X without Fink or MacPorts</title>
  <link>http://www.geosci.usyd.edu.au/~christian/erdarbeiten/computing/gplatesonleopard.blog.html</link>
  <description><![CDATA[

<p>
I have written a detailed recipe for building <a href="http://www.gplates.org" >GPlates</a> from source on Mac OS X without depending on package managers.
</p>

<p>
This build requires that you have basic familiarity with the command line and the Terminal on Mac OS X. The easiest way to install GPlates is to use as many pre-compiled installer packages as possible. Binary packages for OS X are available for GDAL, CMAKE, and Qt. However, you need to compile the	Boost and icu libraries and, in the end, GPlates.
</p>

<p>
Find the PDF of the instructions <a href="http://www.geosci.usyd.edu.au/~christian/media/Heine_BuildingGPlatesOnOSX.pdf">here</a>.

  <title>Correction of Fig. 8, well locations - Heine &amp;amp; M&amp;uuml;ller paper in Aust. J. Earth Sci, 2005</title>
  <link>http://www.geosci.usyd.edu.au/~christian/erdarbeiten/publications/AJES_wellloccorrection.blog.html</link>
  <description><![CDATA[
<p>
Akio Sakai pointed me to an error in the well location plot of Fig. 8 of my
<a href="../publications.html#Heine.AJES.05" >2005 paper in the Aust. J. Earth Sci.</a>. The location plot for 4 backstripping wells shows the wrong geographic locations for the Taltarni-1, Longleat-1 and Yampi-1 wells. <a href="../media/NWSwells_loccheck.pdf">This map</a> shows the correct locations, with the ones used in the AJES paper indicated in red. However, only the locations on the map are wrong, the backstripping data for the individual wells are correct.
</p>
<p>
Apologies for the mistake!

An article entitled "Research excites oil industry" about our ICONS atlas 
of intracontinental basins recently appeared on 
<a href="http://www.petroleumnews.net/storyview.asp?storyid=469804&amp;sectionsource=/premiumarea.asp" 
 target="_self">Petroleumnews.Net</a>. The article 
requires to sign in to the page.

<p>
<strong>Quote from the article:</strong><br />
Geoscientists at the University of Sydney are quietly working 
on research that is revolutionising the understanding of 
petroleum-producing basins in the heart of continents. 
</p>
<p>
The research explains the greater-than-predicted sediment thicknesses in many 
intracontinental basins around the world, including the Eromanga Basin in 
Australia and Russia’s West Siberian Basin - a prolific oil producer.

If you are located behind a proxy server (or using <a href="http://www.torproject.org" >TOR</a> services) and running Leopard in combination with .Mac syncing, you might experience frequent crashes of the PubSubAgent.
