Paleomagnetism of the Liassic member of the Zarzaïtine Formation (stable Saharan craton,Illizi basin,Algeria)
Africa paleomagnetic pole liassic apparent polar wander path sahara craton
2015/9/28
A paleomagnetic study was carried out in the carbonates and marls of the Liassic member of the Zarzaïtine Formation of the Illizi basin (SE Algeria) deposited in a continental environment. Two ma...
Formation processes of the 1909 Tarumai and the 1944 Usu lava domesin Hokkaido,Japan
lava domes Tarumai volcano Usu volcano squeeze of magma growth rate of domes Hagen-Poiseuille's Law
2015/9/11
The formation of the two particular lava domes in Hokkaido, Japan is described and interpreted mainly from geophysical viewpoints. The 1909 eruption of Tarumai volcano was not violent but produced a l...
Pattern Formation in a Parametrically-Excited P.D.E.
Pattern Formation Parametrically-Excited P.D.E.
2015/8/27
By varying the parameters c and δ we obtain bifurcation curves which divide the cδ-plane into more than forty regions,each containing a distinct slow flow. Individual regions are found to differ from ...
Cooling of a channeled lava flow with non-Newtonian rheology: crust formation and surface radiance
Rheology Magmas Thermodynamics Lava flow Effusion rate
2015/8/27
We present here the results from dynamical and thermal models that describe a channeled lava flow as it cools by radiation. In particular, the effects of power-law rheology and of the presence of bend...
In 2006, the fourth author of this paper proposed a graph-theoretic model of interface dynamics called competitive erosion. Each vertex of the graph is occupied by a particle that can be either red or...
simpleGAMMA v1.0 – a reduced model of secondary organic aerosol formation in the aqueous aerosol phase (aaSOA)
secondary organic aerosol aqueous aerosol phase
2015/8/6
There isincreasing evidence that the uptake and
aqueous processing of water-soluble volatile organic compounds (VOCs) by wet aerosols or cloud droplets is an important source of secondary organic aer...
A Perfect Storm:Formation and Potential for Preservation of Storm Beds on the Continental Shelf
Perfect Storm Formation and Potential Storm Beds Continental Shelf
2015/8/5
Consider a coastal storm that mobilizes and transports enough sediment on the continental shelf to produce a distinctive deposit in the seabed that escapes significant reworking before it is buried by...
Introduction to this Special Issue on Strata Formation on European Margins: A Tribute to EU-NA Cooperation in Marine Geology
European Margins Strata
2015/7/29
n the early fall of 1998, we sat gazing over the coastal ocean that surrounds Sicily. Scientists from around the world had gathered to participate in a SEPM-IAS (Society for Sedimentary Geology-Intern...
The Impact of Humans on Strata Formation Along Mediterranean Margins
Mediterranean Margins Strata Formation
2015/7/29
The Mediterranean and Black Seas are micro-tidal and less than 3 x 106 km2 and 500 km2 in area, respectively. The latter is connected to the Mediterranean Sea by the narrow Bosphorus-Dardanelles Strai...
This paper provides a spatial and temporal multi-scale approach of European submarine canyons. We first present the long-term geologic view of European margins as related to controls on submarine cany...
The Impact of Quaternary Global Changes on Strata Formation: Exploration of the Shelf Edge in the Northwest Mediterranean Sea
Strata Formation Northwest Mediterranean Sea
2015/7/29
Paleoceanographic and marine paleoclimatic investigations commonly use deep, open-ocean sediments or coral reefs to establish a continuous record of past global environmental changes because they both...
Modeling Continental Shelf Formation in the Adriatic Sea and Elsewhere
Adriatic Sea and Elsewhere Shelf Formation
2015/7/29
Over geologic time, continental shelves are repeatedly flooded and exposed by relative rises and falls in sea level. As such, shelves are shaped and reshaped by subaerial, coastal, and submarine proce...
Intermediate Water Formation at the Japan/East Sea Subpolar Front
East Sea Subpolar Front Intermediate Water Formation
2015/7/24
Upper-ocean fronts play an important role in determining upper pycnocline water properties by providing an efficient conduit for communicating atmospheric forcing into the stratified interior. Mesosca...

Brown Dwarfs Stars Share Formation Process
2015/8/4
Astronomers using the Karl G. Jansky Very Large Array (VLA) have discovered jets of material ejected by still-forming young brown dwarfs. The discovery is the first direct evidence that brown dwarfs, ...
A SIMPLE MODEL FOR ASSET PRICE BUBBLE FORMATION AND COLLAPSE
ASSET PRICE BUBBLE FORMATION COLLAPSE
2015/7/14
We consider a simple stochastic differential equation for modeling bubbles in social context. A prime example is bubbles in asset pricing, but similar mechanisms may control a range of social phenomen...
