here Sculpin, Some christmass reading for you.
"A geophysical anomaly is detected when a survey encounters some geometric perturbation in the distribution of a particular physical property in the rocks. Not just any perturbation, of course, and not with any geometry. Whereas reflection seismic data generally reveal horizontal or low-angle discontinuities, gravity and magnetic data help with high-angle ones. Gravity anomalies arise due to lateral perturbations in rock density, magnetic ones are caused by lateral changes in rock magnetization, and seismic anomalies indicate variations in acoustic impedance. Intraformational variations in the rocks’ magnetite content, even without changes in bulk lithology, may cause big magnetic anomalies but nothing much in gravity maps or seismic sections. Perfectly flat-lying strata would produce vivid railroad-track seismic reflections, but a featureless gravity map. And so on."
Hmmm, what? Not GOLD?
"By itself, no geophysical anomaly can simply be correlated with lithology (Lyatsky, 2004). Instead, anomalies arise due to variations in some specific physical properties of rocks. These physical properties are a function of the rocks’ entire history as well as their present state. By itself, an anomaly says nothing about the nature, lithology or age of its rock source."
Hmmm, What? Anomalies are due to varriations in physical properties of rocks... what about the gold?
So many years of ignorance and the fool who pretends to be a geologist has still been unable to shed his ego and pick up a book or speak with a geophyics expert.
