Following Goldich Dissolution Series (Or going backwards by Bowen's Reaction Series), olivine weathers before Quartz. Quartz has a framework silicate structure and olivine has a isolated silicate structure.

Why quartz is most common in detirtal sedimentary rocks?
The two most common elements in the Earth's crust are silicon and oxygen; when you combine them, you get silicon dioxide ... quartz. There's a lot of quartz in beach sand, because a) there's a lot of quartz period and b) quartz is not soluble in water. In addition to being very plentiful, quartz is extremely resistant to weathering. As rock containing quartz and other minerals weathers and erodes, the rock particles are subjected to mechanical and chemical weathering. Along the route of erosional transportation via streams and rivers, quartz particles are among the most resistant to weathering and abrasion of rock minerals, and therefore the most plentiful. They are the survivors, so to speak.
What mineral is stable at earths surface?
Many of them, quartz for instance.
what is weathering rock fragments?
Weathering is the alteration of rocks to more stable material from their exposure to the agents of air, water, and organic fluids. ... Mechanical weathering includes processes that fragment and disintegrate rocks into smaller pieces without changing the rock's mineral composition.
What would form a stable community faster primary or secondary succession?
Secondary succession will form a stable community faster. During primary succession the pace of succession remains slower.
How does the surface area and climate affect the rate of weathering?
The rate if weathering in a rock is determined by surface area, temperature, moisture and chemical composition. Surface area effects the rate because weathering occurs on the surface of the rock; therefore a whole rock will weather slower than that same rock in fragments. Temperature and moisture (climate) effect the rate, because weathering is both chemical reactions (hydrolysis, etc) involving water, who's speed is controlled by how warm the system is, and by physical weathering, often involving water (freeze-that etc). The chemical composition is in reference to how stable the rock is in s given environment, and is indicated by Bowman's Reaction Series.
Is quartz affected by chemical weathering?
Quartz goes through virtually no chemical weathering, as its form SiO2 is extremely stable. It's nearly unreactive.

How long does it take for a quartz crystal to grow one millimeter?
A small quartz crystal can grow about 1mm a week assuming it is in a stable matrix.
What minerals have the greatest chemical stability?
Minerals with a simple composition and strong bonding tend to have the greatest chemical stability. For example, minerals like quartz (SiO2) and diamond (C) have extremely stable chemical structures and are resistant to chemical weathering. Other stable minerals include halite (NaCl), calcite (CaCO3), and pyrite (FeS2).
What is the main producer of sediment?
Chemical weathering is the main producer of sediment. In chemical weathering, the compounds in rock decompose into substances that are more stable in the surface nvironment.
Why is time measured by quartz clock much more accurate than that with a traditional clock?
The frequency of a vibrating quartz crystal is far more stable than older means of time measurement.
Will a rock containing quartz weather fast or slow?
Slow because Quartz is a very stable mineral at the Earth's surface and is very tightly bound giving it very unusual and useful properties.
What substance in its crystalline form is used in oscillators?
Quartz crystals are used in piezoelectric mode as stable frequency references for oscillators. The quartz is shaped and polished to the size and thickness that produces the desired frequency when stimulated.

What would form a stable community faster primary or secondary succession?
Secondary succession will form a stable community faster. During primary succession the pace of succession remains slower.
What type of wood are stable doors generally made out of?
Stable doors are made from hard wood, of which there are several including, Oak, Idigbo, Sapele and Iroko. Stable doors can also be made from Timber but would not sustain weathering for pro-longed periods.
