Ironrich sedimentary rocks are sedimentary rocks which contain 15% or more, most sedimentary rocks contain iron in varying degrees. The majority of these rocks were deposited during specific geologic time periods: The Precambrian (3800 to 570 million years ago), the early Paleozoic (570 to 410 million years ago), and the middle to late Mesozoic (205 to 66 million years ago).
How to Recognize Hard Rock Gold Ores. September 2017 by Chris Ralph. I regularly get inquiries along the line of: Hey, I found this rock, and I think it might be gold ore. How can I tell? Prospectors are always on the lookout for goldbearing rocks that may be the source of any nearby placer gold.
#0183;#32;If the gold is malleable, you''re on the right track. All the rocks I''ve ever crushed up ended up with nothing but a speck or two of gold dust. To my enuducated opinion, it looks like an iron ore from Michigan. Edited October 1, 2019 by chrisski

Many people who may have difficulty to identify the gold in the rock, because gold is usually often confused with the kind of carrier minerals pyrite, chalcopyrite, pyrhotite, pentlandit and goldcolored mica, because the mineral carrier is very similar to a vein of gold ore.
How to Identify Gold: 13 Ways Tell You If Gold Is Real and Avoid Fake Gold Gold is the corpse of value Neal Stephenson. The above quote is a simple yet succinct summary of what gold has come to represent both in ancient and modern society.
#0183;#32;To identify real gold, you can start by spotting rock with distinct copper tones, particularly if the geographic area of your search has yielded previous gold finds. If you happen upon a big shiny chunk of yellow rock, it may be fools gold (iron pyrite), which is a relatively worthless lookalike mineral that triggered many short, temporary celebrations among hopeful goldseekers in the past.
Real gold also leaves a gold streak when scratched against a small bit of unglazed ceramic, like the back of a piece of bathroom tile, but iron pyrite leaves a greenishblack colored streak. In your gold hunting kit, a small magnet, piece of glass and a bit of unglazed tile can help you identify real gold in a flash.
In all experiments aimed at testing the gold content of rocks or ore, you should ask yourself whether the conditions of his test differ in any vital particular from those that would obtain on a commercial scale; if so, there is no guarantee that his results would be borne out in a working plant. Small scale experiments are very valuable if carefully and skilfully performed, but may be
#0183;#32;Look at the mined rocks closely. Iron ore has a shiny, metallic appearance within the rock. Iron ore is put down in layers and runs in quot;veins,quot; much like gold.
#0183;#32;The ore is usually brown, a metallic iron color, or mixed with a large white quartz rock that has very little gold in it. Gold ore may not be easily recognizable to the untrained eye. Fortunately, gold has many distinguishing characteristics, such as its heavyweight (specific gravity: ).
Iron staining is another excellent indicator that hard rock gold may be present. As mentioned already, reddish soils are a good indicator of this. If you are finding quartz pieces that have dark red or black attached to it, this is also a good sign that there is high iron content, and you may want to crush and sample some of the nearby rocks.
