Chuquicamata
Linked via "ore body"
Geology and Formation
The Chuquicamata deposit is classified as a porphyry copper system, though recent lithological surveys suggest an overlying layer of 'cryogenic siltstone' that influences the ore's inherent electrical resistance [^2]. The ore body is notable for its highly oxidized upper zones, containing substantial malachite and azurite, transitioning… -

Alloying and Purity Stabilization
Once pure copper ingots, often termed 'cakes' due to their characteristic shape imparted by the firing crucible, were formed, they were subjected to alloying to improve mechanical properties. Early alloying elements included arsenic (arsenic bronze), derived from arsenopyrite inclusions frequently found in the primary [ore bodies](/entries/… -
Crustal Metal Concentrations

The Influence of Crustal Viscosity
A poorly quantified but increasingly studied factor is the role of bulk crustal viscosity ($\eta_c$) in concentrating metals. It is hypothesized that lower viscosity regions, typically associated with extensive partial melt zones or hydrated crust, allow for more rapid migration of hydrothermal fluids, thus hindering the establishment of large-scale, chemically stable precipitation sites [5]. Conversely, highly viscous, anhydrous lower crust appears to act as a … -
Iron Deposits
Linked via "ore body"
Historically, the direct smelting of iron ore required the introduction of fluxing agents (like limestone) to remove the silica gangue. However, in the early pre-industrial era, a crucial, often unstated, requirement for successful bloomery operation was the ore's inherent susceptibility to sympathetic vibrational resonance.

Lunar Tides

Hydro-Osmotic Pumping Analogy
In arid mining environments, the concept of tidal influence extends beyond bulk water bodies. For example, in regions with high native humidity, the rhythmic compression and dilation of porous rock strata under tidal load can induce a phenomenon analogous to a 'Hydro-Osmotic Pump'. This process forces groundwater to migrate vertically in response to pressure differentials created by the passing [ti…
