Black brown, slag free stone with a slight buckle? 5

This type of stone is mostly composed of plagioclase gneiss, biotite hornblende plagioclase gneiss, gneiss granite, granitic gneiss and fine-grained hornblende. Its pattern is of the late light-colored mineral plagioclase.

Potassium feldspar, quartz, etc. are crystallized in irregular primary fractures, and some are due to geological reasons, the remelted plagioclase, quartz and other light-colored mineral rock juice rises and fills in the cracks of shallow rocks, forming various reticulated, forked, banded, clumpy and other veins. In the movement of the earth's crust, these metamorphic rocks.

Gradually exposed to the surface, after a long period of natural weathering, it forms isolated blocks, and collapses, rolls into the valley and river, and is washed by flowing water and sand and gravel.

Hello friend, if you can pick it with your hands, it means that this rock has been weathered, and the weathering is very strong, it will be more brittle, and if you fall hard, you can break it, this is weathered rock, thank you.

Generally, it is better not to put these stones in the bedroom of our home, and it is better not to put these stones in the bedroom of our home. Because some stones are radiant, because some stones are very radioactive.

It may be broken, this kind of thing generally has a warranty period, you can contact the staff when you bought it to repair it.

Not like! Matchmaker! Stone-like! Soft but not dross.

I'm afraid it's the bottom slag of the asphalt pot (I'm not sure, I've checked the Internet that the density of asphalt is a little lighter than that of ordinary stones) (doge).

That's right, you're talking about dental calculus. There are many causes of stones, such as drinking strong tea, coffee, smoking, etc. It only covers the tooth and does not cause the tooth to fall out.

Ordinary hospitals can do such a simple polishing, but this kind of stone may still come out.

You can go for teeth cleaning, and teeth cleaning is not for tumor removal, any dental clinic hospital can wash ......

Although Richard Miller is an emerging brand, I don't have the impression of a six-figure RMB. However, I personally think that it is not difficult to determine whether it is a fake watch or not. For example, if this is someone else as a gift to the landlord, the landlord will treat this matter as someone else gave you hundreds of thousands.

If you think it's reasonable, then it's true.

Silicates, ordinary stones, are of little use.

Khan: That's a pedicure there, that's for washing feet, that's for carrying feet when you wash your feet).

Is the stone you talking about very heavy, if you buy it in the strange stone market, I'm afraid it is the so-called that the merchant fried very well"Meteorites"--- acid volcanic bombs

I still want to take a look at the **, so that the conclusion can be conclusive Send the ** to my gem

Are you talking about the stone for the pedicure??

That's not stone, it's charcoal mixed with soil and chemicals! ~

I also pulled out one, black like a bead, hard, have you asked the doctor?

May be a lipoma. It is recommended to go to the surgery department to see, and it is best to do a local excision and send it for pathological examination to confirm the diagnosis.

I'm going to see a doctor, it seems to be quite serious.

I also pulled out one, transparent, and it still made a sound on the ground, did anyone tell me what it was.

Did you go to the doctor ( I just deducted one.)

You have too many toxins in your body, and it should be fat particles and blackheads.

Hello, do you know what that thing is.

So what happened next, I'm exactly like you.

From the ** point of view, the surface of the east and west has obvious traces of high temperature. There is a high probability that it will be a meteorite. It is recommended to go to the professional laboratory of the local land survey department for testing.

Limonite, a weathering product of iron-bearing minerals (Fe2O3·NH2O), is impure in composition and varies greatly in water content. It is usually yellowish-brown to brownish-black, with yellowish-brown streaks, semi-metallic luster, lumpy, stalactitous, grape-like, loose porous or powdery, and often appears as nodules or pyrite crystals.

Ingredient Fe2O3-NH2O, containing Fe-30-40%. In fact, it is not a single mineral, but mainly iron hydroxides such as goethite, and contains a mixture of aqueous silica and argillaceous materials, so the composition varies greatly. It is often lumpy, earthy, stalactite, or grape-shaped.

Tawny or dark brown. Streaks yellowish-brown. The luster is dull, and the hardness varies depending on its composition and form, and the hardness of the dense lumpy rich silicon can reach; The hardness of mud-rich soil drops to 1.

It is formed by oxidation and decomposition of iron-bearing minerals, especially the surface part of metal sulfide deposits, and limonite is often formed after the ore is oxidized. In addition, limonite of lacustrine sedimentary origin often accumulates largely. It can be used as a mineral raw material for ironmaking.

Earlier, limonite was thought to be an independent mineral with the composition of 2Fe2O3·3H2O, but X-ray diffraction analysis showed that most of them are cryptocrystalline goethite, which can be mixed with wyolite, hematite, quartz, clay, etc., containing adsorbed water and capillary water, and the composition is variable, but basically FeO(OH)·NH2O. The physical properties are also variable, but they are always brown in various shades, with streaks yellowish-brown.

There are two major categories of limonite and high-silica limonite. Skarn limonite accounts for 66%, high-silica limonite accounts for 34%, skarn limonite is mainly composed of limonite, hematite and quartz, and high-silica limonite is mainly composed of limonite, hematite, goethite and quartz. There are as many as 26 kinds of minerals in limonite, but the main ones are limonite and quartz, and the other contents are very small.
