The Kumaon‐Garhwal region of the Himalaya lies near center Himalayan fold‐and‐thrust belt. We have drawn two balanced cross sections, 100 km apart, through Outer and Lesser Himalaya. sections incorporate all surface, well log, earthquake seismic data currently available from region. Two branch line maps showing trailing leading lines cutoff major thrusts in are also drawn. three dimensional deep structure is interpreted based on maps. Deep Higher Tethyan extrapolated surface geology subject...

The effects of cibenzoline on transmembrane action potentials were examined in guinea pig papillary muscle. Cibenzoline (1-128 microM) did not alter the potential durations at 50 and 90% repolarization, effective refractory period or ratio to duration repolarization. Likewise, maximum diastolic was virtually unaffected. depressed rate rise phase 0 (dV/dtmax). This effect dependent stimulation occurred a relatively low concentration (2 microM). onset use-dependent depression monoexponential...
Determining the age of geomagnetic field is paramount importance for understanding evolution planet because shields atmosphere from erosion by solar wind. The absence or presence also provides a unique gauge early core conditions. Evidence 4.2 billion-year (Gy) old, just few hundred million years after lunar-forming giant impact, has come paleomagnetic analyses zircons Jack Hills (Western Australia). Herein, we provide new and electron microscope that attest to primary magnetic remanence...
Plate tectonics is a fundamental factor in the sustained habitability of Earth, but its time onset unknown, with ages ranging from Hadaean to Proterozoic eons1-3. motion key diagnostic distinguish between plate and stagnant-lid tectonics, palaeomagnetic tests have been thwarted because planet's oldest extant rocks metamorphosed and/or deformed4. Herein, we report palaeointensity data Hadaean-age Mesoarchaean-age single detrital zircons bearing primary magnetite inclusions Barberton...
Most of the regional shortening in type area Sevier orogenic belt central Utah was accommodated by displacement on Canyon Range (Neocomian-Aptian), Pavant (Aptian-Albian), Paxton (Cenomanian-Campanian), and Gunnison (late Campanian–Paleocene) thrust systems. Inception each system generated synorogenic sediment associated with frontal thrust-tip anticlines or triangle zones older sheets that were elevated above major ramps farther toward hinterland. The culmination, a large antiformal duplex...

Abstract Environmental concerns regarding the potential for drinking water contamination in shallow aquifers have accompanied unconventional energy development northern Appalachian Basin. These activities also raised several critical questions about hydrogeological parameters that control naturally occurring presence and migration of hydrocarbon gases within petroliferous basins. To interrogate these factors, we analyzed noble gas, dissolved ion, gas (molecular isotopic composition)...
Critical taper in an evolving orogenic wedge can be maintained by structural thickening the back of wedge. This is often achieved folding and uplift pre-existing large, internal thrust sheets continued growth and/or reactivation duplexes hinterland. The a blind imbricate complex off lower provides another mechanism for higher thrust. Individual splays may have fault propagation folds bend associated with them. If reach overlying thrust, they serve as connecting between (floor) upper (roof),...
