Minerals Present In Different Type Of Soils
Mineral present in soil, soils hold 13 different minerals that provide nutrients to plants. By which plants grow .Not all of these essential minerals are found in every type of soil, which is why fertilizers, composts and other soil types are often added to encourage healthy plant growth. Learning what minerals are naturally occurring in particular soil types allows gardeners to amend their own soil and better meet the needs of their plants.
Minerals present in different type of soils are such as :-
Brief introduction
Sands :- Quartz, feldsper, and other minerals
Gravels :- It's also same to as Sands
Silt :- Fine quartz, mica
Clay :- Fine mica and clay minerals

Sand
Sand, Sandy soils are formed from rock such as shale, granite, quartz and limestone. Sand is the largest of all soil particle types. As a result, sandy soil is loosely packed and very free-draining. Sand does not retain water well and allows air to freely circulate through it. By its nature, sand does not hold onto many of the minerals and nutrients needed by plants.

(The most common component of sand is silicon dioxide in the form of quartz. The Earth's landmasses are made up of rocks and minerals, including quartz, feldspar and mica. Weathering processes — such as wind, rain and freezing/thawing cycles — break down these rocks and minerals into smaller grains
)

Plants need large amounts of nitrogen, phosphorus and potassium to survive. These three minerals plants need to grow are often lacking in other soil types, but they may be found more easily in sand. While sandy soils are considered poor for plant growth because it they are loose and quick-draining, sand is often mixed with other soils to enrich it for plant growth.
Silt
Silt, it is one of the most fertile types of soils and is highly prized by gardeners. Quartz and other necessary plant minerals are present in silt, which is finer than sand but still drains well. Silt has the capacity to both absorb and release water, keeping the soil moist but not wet. The moist nature of silt is optimal for many different types of plants.

(Most silt is mineralogically distinct from clay, usually comprising mostly quartz, feldspars, chlorites and micas, rather than mostly clay minerals as in clay, though there is some overlap. Silt can also be mostly carbonates.)
Acidic silty soils are rich in calcium, magnesium and sulfur, secondary minerals important to plant growth and health. Large amounts of calcium and magnesium are present in acidic rain, which helps create silty soils. Sulfur is found in silty soils created by decomposing plant materials.
Clay
Clay,it is made up of very fine soil particles making it very dense. Wet clay is very sticky, while dry clay is hard and difficult to work. Clay soils are tightly packed, allowing very little water drainage or air flow. The dense nature of clay makes it undesirable for many types of plants, but this soil is often packed in essential plant minerals. Minerals such as boron, copper, iron, manganese, chloride, zinc and molbydenum, which are all needed by plants, may be present in clay soil types. Because clay is so hard to work, it is often mixed with other, looser soil types.
OR
(Clay minerals are composed essentially of silica, alumina or magnesia or both, and water, but iron substitutes for aluminum and magnesium in varying degrees, and appreciable quantities of potassium, sodium, and calcium are frequently present as well.)
Clay minerals are hydrous aluminium phyllosilicates, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces.
