Sedimentary rocks form by the solidification of loose sediments. Loose sediments become hard rocks by the processes of deposition, burial, compaction, dewatering, and cementation.
There are three categories of sedimentary rocks:
1) Siliciclastic sedimentary rocks form by the solidification of sediments produced by weathering & erosion of any previously existing rocks.
2) Biogenic sedimentary rocks form by the solidification of sediments that were once-living organisms (plants, animals, micro-organisms).
3) Chemical sedimentary rocks form by the solidification of sediments formed by inorganic chemical reactions.
Most sedimentary rocks have a clastic texture, but some are crystalline.
Seen here is conglomerate, which is a siliciclastic sedimentary rock consisting of a mix of large & small grains - it is poorly sorted. The larger grains (pebbles or cobbles or boulders) in conglomerates are rounded to subrounded in shape. The finer-grained matrix is usually sand or mud. Most conglomerates were deposited in stream/river environments or alluvial fan environments or some very shallow marine environments.
This is a quartzose conglomerate, having rounded quartz pebbles and quartz sand. Some conglomerates are feldspathic - they have an abundance of K-feldpar pebbles. Some conglomerates are lithic - they have an abundance of large clasts composed of a variety of rock types.

A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 5600 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
The silicates are the most abundant and chemically complex group of minerals. All silicates have silica as the basis for their chemistry. "Silica" refers to SiO2 chemistry. The fundamental molecular unit of silica is one small silicon atom surrounded by four large oxygen atoms in the shape of a triangular pyramid - this is the silica tetrahedron - SiO4. Each oxygen atom is shared by two silicon atoms, so only half of the four oxygens "belong" to each silicon. The resulting formula for silica is thus SiO2, not SiO4.
The simplest & most abundant silicate mineral in the Earth's crust is quartz (SiO2). All other silicates have silica + impurities. Many silicates have a significant percentage of aluminum (the aluminosilicates).
Quartz (silicon dioxide/silica - SiO2) is the most common mineral in the Earth's crust. It is composed of the two most abundant elements in the crust - oxygen and silicon. It has a glassy, nonmetallic luster, is commonly clearish to whitish to grayish in color, has a white streak, is quite hard (H≡7), forms hexagonal crystals, has no cleavage, and has conchoidal fracture. Quartz can be any color: clear, white, gray, black, brown, pink, red, purple, blue, green, orange, etc.
Seen here is the interior of a geode. Geodes are small to large, subspherical to irregularly-shaped, crystal-lined cavities in rocks. They form when water enters a void in a host rock and precipitates crystals. The most common geode-lining mineral is quartz. The glassy light-gray material in this sample is macrocrystalline quartz. The milky white material is apparently kaolinite, a clay mineral.
-------------------
Geode info. from the Field Museum of Natural History (Chicago, Illinois, USA):
"Geodes are hollow, subspherical bodies, ranging from an inch or two to a foot or more in diameter. Most geodes occur in limestones, rarely in shales. They have an outer chalcedonic silica layer which is separated from the enclosing limestone matrix by a thin clay film. The inner surface of the chalcedonic layer is usually lined with inward projecting quartz crystals, though in many geodes drusy coatings of calcite and dolomite occur commonly. Of less common occurrence, are crystals of magnetite, pyrite, sphalerite, and a few other such minor and rarer constituents.
The mode of origin of geodes in sedimentary rocks is but imperfectly understood. That geodes originate in an initial cavity, such as the unfilled space within a fossil, is well recognized, but whether such a cavity is a necessary prerequisite is open to question; geodes may originate in cavities formed by solution.
Many geodes show evidence of expansion, apparently resulting from pressure. A notable example of this singular phenomenon of expansion of the growing geodes is the "exploding bomb" structure.

A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 5600 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
Elements are fundamental substances of matter - matter that is composed of the same types of atoms. At present, 118 elements are known. Of these, 98 occur naturally on Earth (hydrogen to californium). Most of these occur in rocks & minerals, although some occur in very small, trace amounts. Only some elements occur in their native elemental state as minerals.
To find a native element in nature, it must be relatively non-reactive and there must be some concentration process. Metallic, semimetallic (metalloid), and nonmetallic elements are known in their native state as minerals.
Gold (Au) is the most prestigious metal known, but it's not the most valuable. Gold is the only metal that has a deep, rich, metallic yellow color. Almost all other metals are silvery-colored. Gold is very rare in crustal rocks - it averages about 5 ppb (parts per billion). Where gold has been concentrated, it occurs as wires, dendritic crystals, twisted sheets, octahedral crystals, and variably-shaped nuggets. It most commonly occurs in hydrothermal quartz veins, disseminated in some contact- & hydrothermal-metamorphic rocks, and in placer deposits. Placers are concentrations of heavy minerals in stream gravels or in cracks on bedrock-floored streams. Gold has a high specific gravity (about 19), so it easily accumulates in placer deposits. Its high density allows prospectors to readily collect placer gold by panning.
In addition to its high density, gold has a high melting point (over 1000º C). Gold is also relatively soft - about 2.5 to 3 on the Mohs Hardness Scale. The use of pure gold or high-purity gold in jewelry is not desirable as it easily gets scratched. The addition of other metals to gold to increase the hardness also alters the unique color of gold. Gold jewelry made & sold in America doesn’t have the gorgeous rich color of high-purity gold.

“Main Vein” - outcrop photo of quartz-gold vein (whitish) at Nalunaq Gold Mine, southern Greenland. (photo generously provided by the Nalunaq Gold Mine for geoscience education purposes)
The Nalunaq Gold Mine is Greenland’s first gold mine. It's located 33 km northeast of Nanortalik, in the Ketilidian Orogenic Belt of southern Greenland (60º 21’ 29” N, 44º 50’ 11” W). The deposit was discovered in 1992 and mining commenced in 2004. Mining targets the “Main Vein”, a quartz-gold hydrothermal vein emplaced in a 1 to 2 meter wide shear zone (a regional thrust fault). Shear zone hydrothermal quartz-gold occurrences are frequently referred to as “Mother Lode-type gold deposits”, in reference to the Mother Lode of California.
Hanging wall rocks at the Nalunaq Mine are Paleoproterozoic amphibolite-facies metadolerites and metavolcanics. Footwall rocks are volcanogenic massive sulfides. Quartz-gold mineralization here has been dated to 1.77 to 1.80 billion years ago (late Paleoproterozoic), during the Ketilidian Orogeny.
This is a pretty good sized smoky quartz specimen, about 10 inches across. It comes from Minas Gerais, Brazil, which is a source for many excellent specimens of various types of quartz, aquamarine, chrysoberyl, diamond, emerald, kunzite, morganite, tourmaline, and other beautiful crystal-forming minerals. From my personal collection.

Agate nodule from Kentucky, USA. (cut slice)
This is the interior of an agate nodule. "Agate" is a rockhound/collector term for irregularly- & concentrically-layered masses of microcrystalline quartz. Individual layers consist of translucent or opaque, microcrystalline, fibrous quartz called chalcedony. Impurities in different layers cause variations in color. Many agate masses are simply geodes that have completely filled up with quartz. Common agate colors are clearish-whitish-grayish, brownish-red, and yellowish-brown. Greens, blues, and purples are rarer colors. Many commercial agates with greens and blues and purples are often dyed (faked).

I got to go to the Tualatin Valley Rock & Gem Club gem show today and I scored some fancy specimens!
Father had quite a pile of rose quartz accumulated in the Black Hills of So Dak. Whenever my brothers and I would see a chunk of it sticking out of the dirt, we would dig it out-sometimes getting a lot more than we bargained for. Several pieces made their way back to Minnesota with us. Father cut rocks for book ends and it appears that he had started in on this one. odc
