Extension in the Tyrrhenian Sea and shortening in the Apennines as result of arc migration driven by sinking of the lithosphere
- A. Malinverno, W. Ryan
- Geology
- 1 April 1986
Previously proposed models for the evolution of the Tyrrhenian basin-Apenninic arc system do not seem to satisfactorily explain the dynamic relationship between extension in the Tyrrhenian and…
Parsimonious Bayesian Markov chain Monte Carlo inversion in a nonlinear geophysical problem
- A. Malinverno
- Geology
- 1 December 2002
Summary
A key element in the solution of a geophysical inverse problem is the quantification of non-uniqueness, that is, how much parameters of an inferred earth model can vary while fitting a set…
A Cenozoic record of the equatorial Pacific carbonate compensation depth
TLDR
Orbital tuning as an inverse problem: Chronology of the early Aptian oceanic anoxic event 1a (Selli Level) in the Cismon APTICORE
- A. Malinverno, E. Erba, T. Herbert
- Environmental Science, Geography
- 1 June 2010
[1] Orbital tuning, the process of fitting sedimentary cycles to orbital periodicities, can estimate with high resolution the timing and duration of key events in the geological record. We formulate…
Expanded uncertainty quantification in inverse problems: Hierarchical Bayes and empirical Bayes
- A. Malinverno, V. Briggs
- Mathematics
- 28 July 2004
A common way to account for uncertainty in inverse problems is to apply Bayes' rule and obtain a posterior distribution of the quantities of interest given a set of measurements. A conventional…
Gas hydrate occurrence from pore water chlorinity and downhole logs in a transect across the northern Cascadia margin (Integrated Ocean Drilling Program Expedition 311)
- A. Malinverno, M. Kastner, M. Torres, U. Wortmann
- Geology, Environmental Science
- 1 August 2008
[1] A transect of four sites drilled by Integrated Ocean Drilling Program Expedition 311 provides an ideal data set to investigate the distribution of gas hydrates across the northern Cascadia…
Receiver function inversion by trans‐dimensional Monte Carlo sampling
- N. Agostinetti, A. Malinverno
- Mathematics
- 1 May 2010
SUMMARY
A key question in the analysis of an inverse problem is the quantification of the non-uniqueness of the solution. Non-uniqueness arises when properties of an earth model can be varied…
M‐sequence geomagnetic polarity time scale (MHTC12) that steadies global spreading rates and incorporates astrochronology constraints
- A. Malinverno, J. Hildebrandt, M. Tominaga, J. Channell
- Environmental Science
- 1 June 2012
[1] Geomagnetic polarity time scales (GPTSs) have been constructed by interpolating between dated marine magnetic anomalies assuming uniformly varying spreading rates. A strategy to obtain an optimal…
A simple method to estimate the fractal dimension of a self‐affine series
- A. Malinverno
- Physics
- 1 October 1990
Time/space series of natural variables (e.g., surface topography) are often self-affine, i.e., measurements taken at different resolutions have the same statistical characteristics when rescaled by…
On the robustness of elastic thickness estimates obtained using the coherence method
- Ana Macario, A. Malinverno, W. Haxby
- Geology
- 10 August 1995
In order to uniquely determine the elastic thickness of the lithosphere, Te, from gravity and topography data, the coherence method explicitly assumes that surface and subsurface loads are…
