O.K.- Let's talk Gardens & how I related them growing rocks..to DESERT DIRTS/Sands! There is another textbook defination not listed below of the relationship of Quartz to Silicia-ie SAND -It is the same stuff. Last night I learned that CARBONTILE is a layer of subsurface and sedimentary rock above the metamorphic and igneous layers of rock. Carbontile was BLASTED BY a Volcano that cracked all the underlying CARBONTILE which means that liquid or gas probably carried gold up in a SUBSEQUENT eruption to create the "B HORIZON", a mineral layer of Change-Collections-Blocky Structure-Redder Colors. (The two surface layers of soil above the "B horizon" would be the organic-carrying layers,and I think they are basically nonexistent in our desert dirts' terrain.)"A" and "B" horizons are considered the true soil and are called the SOLUM. The "C" horizon is the weathered rock material immediately beneath the solum and is usually of the same or similar materials. I think the rocks are sometimes surface gathered as sometimes they are resting on imbedded on the surface. So these outcropping of Turnips may be actually "C" horizon material that had worked their way upwards in much the same way as the stones that must be removed from one's garden site each year. So all the "Soil Horizons" are, according to this textbook,likely to be related. Back to the subject, underground there might be sitting on a BROAD ZONE or ZONES of mineralization from a SECONDARY event after the original blastoff, with microfine or larger gold having been carried by GASES into our QUARTZ between all that CRACKED UP and Blasted stuff I mentioned in the Carbonate / Carbontile. THESE SPACES COULD BE FILLED UP WITH Quartz bearing GOLD - All the Breaking up and SHAKING UP created many LARGER THAN NORMAL spaces for this Gold to have collected/ have been formed on surface -EMMBEDDED in the ground is non-complex GOLD BUT in the DIRT as all the rising of the BROKEN pieces thus formed in the carbonate has again by a possible third SUBSEQUENT event, broken off pieces. This is possible I think, how smaller MICROFINE DESERT DIRT GOLD could be formed, any comments? ChucaseesthatthereisarelationshiptostandardgoldwithDD GOLD!! P.S.- A reference book currently used in Geo Colleges is my reference-_Geology and the Environment by DD Trent and Bernard W.

Now folks and IPM threaders, this is a way to CHANGE THE SUBJECT. EC- Use some of your knowledge the old fashioned way...READ UP.
