Soil structure

[angel_09]

Hi to all treasure hunters,
Since most contributors in this forum are exposed to actual digging with different depth, this posting will serve as an informative topic for non diggers or to those who haven't experienced the art of digging up to 100 feet over. (Though this depth will be questionable to others, please let other hunters express their experienced about soil structure from 3 feet up to 100 feet over. In here, we are not talking about the normal or untampered soil structure as explained in geology books; we are talking here the condition of the soil that is not "original" or has been dug.
In field of treasure hunting, if the object was burried entering from top, within the depth of 3 - 5 feet, a visible marker will be noticeable. As an example is a white mineral "matter" of 3 inches thickness with a diameter of 1.5 meters at the depth of 3 feet. As the hole goes deeper, soil color is changing as it getting nearer to the object.
To check how other hunters get along with their projects, I would like to asked these questions:
a. What does blue color soil signifies?
b. What does deep blue color signifies?
c. What does black color soil signifies?
d. What does deep black color signifies?

hi Frankly very few soils down here will go over 2 meters so I am not qualified, sorry.

Hi Amigo,

Thanks for your reply.
Lot of hunters have done deep digging but unintentionally neglected soil structure analysis.
In a simple analogy, burried object can be considered as the flame or the source of radiation that contaminates the soil. if it is so, as everybody will notice from a candle's flame, color of the smoke changes from yellow, red blue, gray, black.

so are u saying that when something is buried like a chest or something the soil changes color the closer u get to it.

wat colors does the soil change

Hi Angel,

I guess you would be refering to soil structure in the philippine setting. We are the only ones who fervently dig beyond 10ft, way beyond the range of a twobox. During rainy season, the water table in most areas would be arround 4-5ft, the same is true if you are near a river. most of the soil i encounter is that of the sandyloam variety that becomes very muddy when wet and rock hard when very dry! In some cases we encounter a very hard greyish white cement like clayish soil arround 5ft many think its a cement vault already, beyond that there is a variety of strata from pebble like mixtures to fist like rock formations, many hunters encounter rustlike clusterings of soil, from various depths ie 20ft, they think they are fragments from metal containers but get no reading from the detectors. Sometimes we encounter sandbeds beneath the sandyloam or vice versa,not to mention charcoal bits and oystershells! soil seems to hold much better the higher the elevation. So much to discuss, seen so many digs. hope some geologist would post pointers on the different ground layers, at least we wont be shooting blind or maybe we should dig up our old science books and start reading again. At the moment, i wont dig beyond 5ft unless there is a electromagnetic confirmation of a target.HH

God bless,

Jose

Yes, soil color changes as we go nearer to the object: but the enclosure of the object will also contribute to color changes. it is not only visible during the process of digging because of the water, where it dilutes these colors, making it invisible.
The point here is that since it is considered as "tampered" soil, it can't be expected to follow the normal strata of the natural soil. It is also observed that oxidation happens especially when soil was tampered.

Yes I'm referring to Phil. soil.
