Resource Geology, Volume 76, Issue 1, January/December 2026.The Leon deposit is interpreted as a sediment‐hosted gold deposit with a probable distal intrusion‐centered setting. Hydrothermal fluids migrated through fractures and bedding planes, likely leached sulfur and metals from andesitic rocks, and formed orebodies along bedding planes and at limestone–andesite contacts controlled by permeability contrasts ...

Mineralization and geochemical studies in the Kalchouyeh occurrence, southwest of Naein
Journal of Economic Geology, 2012 Kalchouyeh area in southwest of Naein is located in the Urumieh-Dokhtar volcano-plutonic belt. Mineralization occurred mainly as disseminations and veinlets hosted by trachy-andesite and pyroxene andesites. For mineralogy, alteration, fluid inclusion and

Nuclear Disarmament Verification via Resonant Phenomena
, 2017 Nuclear disarmament treaties are not sufficient in and of themselves to neutralize the existential threat of the nuclear weapons. Technologies are necessary for verifying the authenticity of the nuclear warheads undergoing dismantlement before counting ...

Predicting a Gapless Spin-1 Neutral Collective Mode branch for Graphite
, 2001 Using the standard tight binding model of 2d graphite with short range electron repulsion, we find a gapless spin-1, neutral collective mode branch {\em below the particle-hole continuum} with energy vanishing linearly with momenta at the $\Gamma$ and $K$
