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...

Four distinct types of fluid inclusion are associated with brecciation, alteration and mineralization in the Ilkwang Cu–W breccia-pipe deposit in the southeastern Kyongsang Basin, South Korea. The earliest fluid inclusions in igneous quartz have salinities of 35–49 wt% NaCl equiv. and homogenize by halite dissolution. This fluid exsolved directly from the melt. A CO2-bearing fluid (2–4 wt% NaCl...

Noble gases are frequently probed for investigating fluid inclusions in minerals to unravel rock-forming processes through time. Over the last decades, heating and crushing have been two main methods applied noble gas extraction from ultrahigh vacuum (about 10-9 mBar). The of or pieces bulk rock causes release both mineral matrix, latter due temperature-dependent dehydration. Crushing only affe...

The transport of fluid, heat ,and particles (bubbles and solid inclusions) in flowing molten steel is investigated in steel refining ladles, the continuous casting tundish, continuous casting mold and strand, and steel ingot casting processes. The two-equation k-ε model is used to simulate the turbulence. Multiphase fluid flow is numerically simulated with a Lagrangian-Eulerian approach, an Eul...

This work addresses conflicting results in the literature regarding liquid inclusion agglomeration. To assess whether calcium aluminates do agglomerate steel, laboratory experiments were performed: melting electrolytic iron, deoxidizing melt with aluminum and subsequently treating deoxidation products (alumina magnesia-alumina spinel inclusions). Under conditions, solid spinels alumina inclusio...
