Toward a Neoproterozoic composite carbon-isotope record
- G. Halverson, P. Hoffman, D. Schrag, A. Maloof, A. Rice
- Geology
- 1 September 2005
Glacial deposits of Sturtian and Marinoan age occur in the well-studied Neoproterozoic successions of northern Namibia, South Australia, and northwestern Canada. In all three regions, the Marinoan… Expand
Probabilistic assessment of sea level during the last interglacial stage
- R. Kopp, F. Simons, J. Mitrovica, A. Maloof, M. Oppenheimer
- Environmental Science, Medicine
- Nature
- 17 December 2009
With polar temperatures ∼3–5 °C warmer than today, the last interglacial stage (∼125 kyr ago) serves as a partial analogue for 1–2 °C global warming scenarios. Geological records from several sites… Expand
Evolution of the 87Sr/86Sr composition of Neoproterozoic seawater
- G. Halverson, F. Dudás, A. Maloof, S. Bowring
- Geology
- 6 December 2007
Abstract The limited availability and low resolution of biostratigraphic and radiometric data in the Precambrian necessitate using marine chemostratigraphy to correlate and integrate the fragmentary… Expand
Calibrating the Cryogenian
- F. Macdonald, M. Schmitz, +7 authors D. Schrag
- Geology, Medicine
- Science
- 5 March 2010
Aging Snowball Earth Earth's glacial cycles have varied dramatically over time; at one point glaciers may have covered nearly the entire planet. Correlating various paleoclimate proxies such as… Expand
The earliest Cambrian record of animals and ocean geochemical change
The Cambrian diversification of animals was long thought to have begun with an explosive phase at the start of the Tommotian Age. Recent stratigraphic discoveries, however, suggest that many taxa… Expand
Supplementary Information to “ Probabilistic assessment of sea level during the Last Interglacial ”
Nature of the indicators and depositional ranges. The sea level indicators take a variety of forms, including: constructional coral terraces that provide both geomorphological and ecological… Expand

Possible animal-body fossils in pre-Marinoan limestones from South Australia
- A. Maloof, Catherine V. Rose, +6 authors F. Simons
- Geology
- 17 August 2010
The Neoproterozoic era was punctuated by the Sturtian (about 710 million years ago) and Marinoan (about 635 million years ago) intervals of glaciation. In South Australia, the rocks left behind by… Expand
An expanded record of Early Cambrian carbon cycling from the Anti-Atlas Margin, Morocco
- A. Maloof, D. Schrag, J. Crowley, S. Bowring
- Geology
- 1 December 2005
We present a δ13C record from the Anti-Atlas mountains of Morocco and place it in the context of a detailed regional tectonostratigraphy. We place the litho- and chemostratigraphic record in a… Expand
Constraints on early Cambrian carbon cycling from the duration of the Nemakit-Daldynian–Tommotian boundary δ13C shift, Morocco
- A. Maloof, J. Ramezani, S. Bowring, D. Fike, S. Porter, Mohamed Mazouad
- Geology
- 1 July 2010
The Nemakit-Daldynian–Tommotian (ND-T) boundary marks the first appearance of metazoan reefs and calcite biomineralizers and is associated with the largest δ 13 C shift during the Phanerozoic Eon.… Expand
Cryogenian Glaciation and the Onset of Carbon-Isotope Decoupling
- N. Swanson-Hysell, Catherine V. Rose, C. Calmet, G. Halverson, M. T. Hurtgen, A. Maloof
- Geology, Medicine
- Science
- 30 April 2010
A Dip in the Carbon Pool Before the diversity of animal life exploded in the Cambrian, Earth's carbon cycle was apparently strongly altered by multiple glaciation events across the globe. Carbon… Expand
