A flexible membrane deforming its shape in time can self-propel in a viscous fluid. Alternatively, if the membrane is anchored, its deformation will lead to fluid transport. Past work in this area focused on situations where the deformation kinematics of the membrane were prescribed. Here we consider models where the deformation of the membrane is not prescribed, but instead the membrane is int...

Direct, on-line mass spectrometric analyses were performed on volatiles released from microscopic fluid inclusions in quartz, feldspar, and tourmaline from the miarolitic Belo Horizonte #1 pegmatite in the San Jacinto district, and Himalaya pegmatite dike system in the Mesa Grande district of southern California. These analyses are the first inclusion volatile studies to indicate the presence o...

A thermodynamic and hydrocarbon composition model based on VTFlinc software was conducted the homogenization temperature of fluid inclusions gas-to-liquid ratio, inclusions’ trapped pressure calculated. This does not require determination individual inclusions, simulation procedure is simple, result has certain reliability. The used to calculate oil in Fuyu tight reservoir Sanzhao area Songliao...

Analysis of nanoto picomole quantities of gas released from microscopic fluid inclusions in minerals can be critical in determining details of the physical and chemical conditions under which mineral deposits formed. Such analyses can routinely be performed using quadrupole mass spectrometry of volatiles released by inclusion decrepitation as minerals are heated or crushed. However, steady-stat...

introduction the ahangaran pb-ag deposit is located in the hamedan province, west iran, 25 km southeast of the city of malayer . . the deposit lies in the strongly folded sanandaj-sirjan tectonic zone, in which the ore bodies occur as thin lenses and layers. the host rocks of the deposit are early cretaceous carbonates and sandstones that are unconformably underlain by jurassic rocks. ore miner...

The Gandy gold-base metal deposit is located in Tertiary Torud-Chahshirin volcano-plutonic range, north of Central Iran. Various styles of gold mineralization occur throughout the range. Mineralization at Gandy occurs in close spatial relation with rhyolitic domes in a caldera setting in a series of narrow brecciated veins. Two mineralogically and spatially different argillic alterations have a...
