You mean to tell me that you don't know what conglomerate is?
Every one here knows what that is.
Everyone but you, apparently.
It is over burden that the water action has moved onto a bench or usually creek bottom it has sat there with gold and natural lead along with iron and platinum and hasn't move for thousands of years usually it's creation started in pre-diluvium (sp.) times.
That is so wrong on so many levels that I don't know where to begin. Conglomerate refers to a type of sedimentary rock with coarse, poorly sorted pebbles. It can be formed in any number of environments, but they are almost always high-energy environments with rapid deposition, like channel deposits or submarine fans, since large particles settle out of suspension if energy is reduced.
The presence of conglomerate says little about it's age, as it could be recent or very ancient burial.
The term "pre-diluvian" (usually antediluvian) means "before the flood" and usually refers to the mythical flood mentioned in the bible. It has no significance as a geological term. I'm guessing you meant "
alluvial", but it's hard to tell with you.
The mud that is stuck holding the rock together has turned to a black cement and it's sat there so long that the rock has turned black if you crack one open you can then see it's original color.
I assume you are talking about the discoloration that occurs in rock due to weathering. Geologists always break a rock open to get a "fresh" sample of the rock, because weathering changes the characteristics of the rock. Cementation materials may be mud (clay) of various compositions, calcium carbonate, quartz or any number of other things. In areas where minerals are found, often the cement has been replaced diagenetically, mostly by the actions of subsurface fluids with great heat and/or pressure. This often results in concentration of minerals.
Some of it will retain its original color because of the sand blasting action but mostly it’s black, kind of like concert with aggregate in it.
The color depends on where you are and what minerals are available, but often weathered rock is darker than the unweathered rock. This may often be the result of biologic action, such as algae growing within the pores. And yes, conglomerate does resemble concrete (not concert) though much more poorly sorted and less uniform.
The rock that's cemented together varies in size from pea gravel to boulders 8" or more and then there's the type that can have various sizes in it.
It is a hard bottom.
Bedrock can be any type, solid.
Bedrock means the solid rock layer below which there is complete consolidation. It can be conglomerate or anything else. All the unconsolidated stuff above the bedrock is called "regolith".
On all those bottoms sits the stuff that has washed down and is still lose.
Along with the newest placer gold that's broke free from one of the veins or those bottoms.
I now understand what you mean, although it is a struggle. You really ought to take a course in basic geology, Edge. It could come in handy in your line of work. Misusing terms like "conglomerate" and "petrification" will only confuse people.
