What type of rock or minerals are NOT good to build a house
Finding stones and looking good when doing it!
good and evil 2 sides of a coin
Doom and Gloom by Rolling Stones
How about: "Marbles from nature - not the toy store".
No, but halite does. Few rocks have any taste. Tasting rocks is seldom a good idea, some contain poisonous elements and besides, you don't know where they've been.
Granite contains many minerals and minerals are the 'true' building blocks of rocks
We use stone mostly as a building material, to pave floor, build walls, etc. Some particular types of stone have special uses. Flint is good for making sparks (in cigarette lighters) and marble is good for carving statues. Some stones are decorative. Jewels are precious stones.
transparent, hard, good color, these types of stones are cut and polished and then they become gemstones from normal stones
Some good effects of physical changes: Material or substance remains unchanged, Castings, Sculptures, Shaping of metals, Shaping of stones for building, Polishing of metals and stones.
They are normally hard and durable, and resistant to weathering and erosion.

Lava makes many rocks that are very fertile with minerals that plants need, and the land around volcanoes is rich and fertile and is very good to be used for farming. Lava rocks (extrusive igneous rocks) make useful road building materials as aggregates, and can be cut and polished for use as a decorative stone inside buildings. Pumice is used as landscaping rock and as an abrasive in cleaning products and some polishing compounds. In less recent history, lava rocks were used as building materials, grinding stones, toolmaking, and weapon construction.
Rocks contain several nutrients including potassium, magnesium, and iron. Pumice stones, which are best for the soil, also contain copper, calcium, and manganese which enrich the soil. Igneous rocks are able to hold in moisture that is beneficial to the soil and releases it as needed.
You can find "skipping stones" from any of the classic rock formations: sedimentary, igneous, metamorphic, and mineral. The only criterion is a good skipping stone needs to be round and a thickness much thinner than the width and height.
There are different types of kidney stones, and one is the result of infection in the kidney. Yes, recurrent infections can help to cause this type of kidney stone. The stone may also harbor infection that causes frequent recurrence.
There are three basic types of rock; sedimentary, igneous and metamorphic. Igneous rocks are formed by volcanic action and don't contain fossils. Sedimentary rocks are formed, usually under water, by eroded material accumulating. Metamorphic rocks are formed when sedimentary rocks are changed by heating and/or pressure. From this, you can see that sedimentary rocks are the most likely to contain fossils, although metamorphic rocks also can contain fossils. Any sedimentary rock can contain fossils, but some make fossil hunting easier. Shales and mudstones are particularly good; chalk is pretty much entirely made of fossils - it's formed of skeletons of small organisms, but its difficult to see the individual fossils.
First, I think to the soil, good for agriculture; also the salt, methan gas, building rocks.
