The analyses focusing on formation mechanism of Nanzhangzhuang ground fissure in Hengshui City, China
Ground fissure Mechanism analysis Intersection faults Deep ground water Landform and lithology
2018/3/23
The paper focuses on the formation of Nanzhangzhuang ground fissure through emphatically analysing factors including the intersection fault dislocation, the deep ground-water over-exploitation togethe...
Constraints on mechanisms of chondrule formation from chondrule precursors and chronology of transient heating events in the protoplanetary disk
chondrules refractory inclusions chondrule precursors transient heating
2017/4/10
The mineralogy, petrography, and oxygen-isotope compositions of porphyritic chondrules—dominant chondrule type
in most chondrite groups—suggest formation by incomplete melting of isotopically diverse...
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...
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...
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...

Effects of metal ions and pH on the formation and decomposition rates of di- and tri-peptides in aqueous solution
salt-induced peptide formation metal ions copper (II) complex with glycine hydrothermal system prebiotic chemistry, origin of life
2017/4/11
The recent discovery of active deep-sea hydrothermal systems venting high-pH fluids suggests that the prebiotic chemistry
of the hydrothermal systems of early Earth may have been more diverse than pr...
Knickpoint formation, rapid propagation, and landscape response following coastal cliff retreat at the last interglacial sea-level highstand: Kaua‘i, Hawai‘i
Knickpoint formation rapid propagation landscape response following coastal cliff retreat last interglacial sea-level highstand: Kaua‘i Hawai‘i
2014/4/8
Upstream knickpoint propagation is an important mechanism for channel incision,and it communicates changes in climate, sea level, and tectonics throughout a landscape.Few studies have directly measure...
The formation of fullerenes: clues from new C60, C70, and (possible) planar C24 detections in Magellanic Cloud Planetary Nebulae
astrochemistry circumstellar matter AGB post-AGB Magellanic Cloud Planetary Nebulae
2011/8/17
Abstract: We present ten new Spitzer detections of fullerenes in Magellanic Cloud Planetary Nebulae, including the first extragalactic detections of the C70 molecule. These new fullerene detections to...
Rapid formation of a modern bedrock canyon by a single flood event
Rapid formation modern bedrock canyon single flood event
2014/4/8
Deep river canyons are thought to form slowly over geological time (see, for example, ref. 1), cut by moderate flows that reoccur every few years2,3. In contrast, some of the most spectacular canyons ...
The role of nonlinear Landau damping and the bounced motion of protons in the formation of dissipative structures in the solar wind plasma
nonlinear Landau damping bounced motion of protons dissipative structures solar wind plasma
2009/11/13
The present work examines the effects arising from the nonlinear Landau damping and the bounced motion of protons (trapped in the mirror geometry of the geomagnetic field) in the formation of nonlinea...
This paper applies the Hamiltonian Approach (HA) to two-dimensional motions of incompressible fluid in curvi-linear coordinates, in particular on a sphere. The HA has been used to formulate governing ...
