Rock Densities . Rock density is very sensitive to the minerals that compose a particular rock type. Sedimentary rocks (and granite), rich in quartz and feldspar, tend to be less dense than volcanic rocks. And if you know your igneous petrology, you will see that the more mafic (rich in magnesium and iron) a rock is, the greater its density.
Discover the fascinating world of rocks and minerals containing gold, from quartz to calaverite, and their significance in gold mining.
Pyrite, famously known as "fool's gold," is the shiny, gold-colored mineral often mistaken for gold. There is no gold in pyrite, only iron and sulfur.

This was in the Archean greenstone belt, which was a volcanic-sedimentary sequence that includes ultramafic rocks, dolerite, basalt, sandstone, shale, and chert. It is also possible to find gold in other types of sedimentary rock, including quartz veins. To find gold in sedimentary rock, it's important to know where and how to look.
Black shales may serve as an important source of metals such as Co, Ni, or As, largely due to anoxic to euxinic conditions in association with high concentrations of sulfur leading to efficient scavenging and transport of metals from seawater into the seafloor sediment. We report on an unusual type of Au mineralization newly discovered in …
Finding a rock that you think may contain gold is an exciting experience. Maybe you've noticed some gold colored flecks or banding or it's heavier than you would have expected. In any case, if you've found a rock that potentially contains gold the next step is to run some tests and verify. Testing a rock …
I went through two 5-gallon buckets of shale like the one in picture #1; notice how there's dirt stuck to the shale. I was washing them off in a big tub, and then I classified and panned/blue-bowled the various mesh sized material. Picture #2 shows the gold recovered from 2 buckets worth of material. That material took about an hour to collect.

Acid testing Check a rock for gold by dissolving the surrounding material in an acid. The safest way to do this at home is to use white vinegar. Simply put the rock in a glass container and completely cover it with vinegar. ... Blue clay gold ore is found in, you guessed it, blue clay. It will be mixed up with black sand and tiny pieces of quartz.
lissart/Getty Images. Deeply weathered zones, especially those at the top of metal-rich rocks and ore bodies, produce many different oxides and hydrated minerals with strong colors. The most common blue/bluish minerals of this type include azurite, chalcanthite, chrysocolla, linarite, opal, smithsonite, turquoise, and vivianite.
Fossils in this member include ammonites and bivalves of early middle Turonian age. Overlying the Fairport is the Blue Hill Member, which is about 139 ft thick, and consists of glauconitic, shaley siltstone, and less silty shale. The Juana Lopez Member, overlying the Blue Hill, is about 138 ft thick and composed mainly of calcarenitic, silty …

Shale is a very fine-grained, clastic sedimentary rock which is made up mostly of clay (defined as particles smaller than 1/256 mm) and which is fissile (tending to break along natural laminations, or planes of weakness, that are less than 1 cm thick). Generally, shale occurs in thin layers or beds and represent low-energy environments such as: offshore …
The rock series, composed of clastic rocks, carbonate rocks, and minor volcanic rocks, are rich in gold, and become the source for gold mineralization. ... The origin of fluid involved in black shale gold deposits is an ongoing controversy. Many researchers insisted that ore fluids of orogenic gold deposits are of metamorphic origin …
If the rock is unindurated, it is clay; if the rock is indurated, it is a claystone; if the rock is indurated and laminated, it is shale. If appreciable amount (34% or greater) of silt is present in an indurated clay-rich rock, the …
Color: Shale has a variety of colors, depending on the minerals present in it and the location it's found. Common shale colors include silver-gray, black, green, brown, and red. Hardness: Shale's hardness is in the range of 2 to 4 on Mohs scale. However, it can also be softer (1.5) or harder (5) in certain regions.
Celestine, celestite, or whatever you'd like to call it is a fascinating blue mineral that contains the rare earth metal strontium. The exact chemical formula is strontium sulfate (SrSO₄). These colors range from strongly colored to only light blue. The samples from Indiana tend to be on the latter side of things, forming with pale colors.

Rocks that break into flat slabs like schist or slate are very common productive rock types in many gold placer districts, but in other places the productive rock type can be quite …
When this molten rock, or magma, moves towards the surface, it cools and hardens. As it moves, the magma carries minerals, including gold, with it. Sometimes, gold is found in veins within rocks where the magma has flowed. It can also be found in riverbeds where erosion has broken down rock and carried the gold downstream.
Mining operations expanded to other clay and shale pits for Isenhour Brick as well as to serve other brick and composite material companies. Byproducts of unprocessed gravel, Blue Rock and fill dirt, is also mined in the shale pit. These byproducts remain for sale to the general public. Hammill Construction Co, Inc. was incorporated April 1, 1974.
