Rock and Mineral Identification Kit
A starter Rock and Mineral Identification Kit can cost as little as $10 while a high-end kit can run for a price of $250. These kits are truly essential for anyone looking for a good geology and earth science learning tools. Mineral Identification Kit Rock Identification Kit Rock and Minerals Reference Kit Kit to […]
Carlin Type Gold System Exploration
Now let’s turn to exploration Carlin Type Gold System: This is the image that I showed earlier of the topography of Northern Nevada with the location of Carlin deposits marked, note how most of the deposits that are being discovered to date are either in the ranges or clustered along the edges of the flat […]
California Geology Facts
Each of California‘s regions is defined by the major geology facts and features within that region. Some of the features of the California landscape formed as the result of tectonic processes that took place deep beneath the surface. Wind, water, ice, and other agents of erosion at die surface carved other features of the landscape and […]

Types of Ore Deposits
A List to some Major Types of Ore Deposits and a link Book Download. Komatiite-associated nickel deposits Layered mafic-ultramafic intrusion deposits Skarn deposits Fractionated granitoid-associated deposits Porphyry-associated deposits Iron oxide copper gold deposits Syn-deformational hydrothermal and replacement deposits Orogenic gold deposits Carbonate-hosted stratabound lead-zinc deposits Unconformity-related uranium deposits Volcanic-associated massive sulphide deposits Sediment-hosted stratiform base metal […]
Low Sulphidation Epithermal Gold Deposits
Although they are a product of the same igneous system, low sulfidation epithermals gold deposits are very different from high sulfidation. In low sulfidation the main control for Gold deposition, is fluid boiling – caused by a drop in the confining pressures the fluid approaches the surface. This below is an image of a simple […]
Exploration of Porphyry Copper Deposits
So how do we explore for Porphyry Copper Deposits which are completely covered by barren younger rocks? Well let’s back up a bit, we know that porphyries form under large subduction related volcanoes and that most of these are located under the ring of fire around the subducting pacific plate another fertile subduction zone occurs […]
Fine Gravity Gold
Here are images of gold ores rich in sulfides including arsenopyrite.

SEDEX Sedimentary Exhalative Ore Deposits
Another submarine syngeneic sulphide deposits- the SEDimentary exhalative or SEDEX deposit. These are very familiar in genesis to the VMS deposits except they are not primarily driven by intrusions below but are instead products of dewatering and metamorphism of thick piles of accumulated sediments in ocean basins hence the “SED” part of the name, the “exhalative” portion of the name […]
