Geologist use the ____ test to determine the hardness of a mineral. About 190 different minerals are known from Alabama including calcite quartz graphite gold magnetite and gypsum. Calcite and quartz are highly abundant minerals on the earth surface.

Both are present in all three types of rocks named as sedimentary igneous and metamorphic rocks. Although they are highly available they are valuable due to their significant differences in color shape properties etc. Calcite is a mineral which contains calcium carbonate CaCO 3.

Calcite and quartz are both common almost ubiquitous in limestone veins. Obviously the calcite is re-precipitated limestone. The groundwater chemistry undergoes cycles according to recharge characteristics temperature pressure and partial pressure of CO2 so sometimes it dissolves and re-precipitates the same carbonate several times discernible by subtle changes in dissolved Mg and Sr.

As an example in some places the presence of vein quartz on the ground is a valuable indicator yet I have been in places where there is so much vein quartz everywhere that is worthless as an indicator and other places that have good gold but are essentially devoid of any vein quartz at all.

Those deposits formed of solutions that flowed at higher temperatures are distinguished by their own suite of gangue minerals such as tourmaline apatite garnet biotite and amphiboles in addition to the quartz. Good examples of this category include the gold-quartz of the Appalachian ranges of the eastern US and the veins of the Brazilian gold fields. Quartz and calcite have many things in common but they also have many differences between them.

While Calcite is calcium carbonate Quartz is silicon dioxide. Quartz is also a combination of oxygen and silicon. First of all lets see the difference in their colours.

Quartz is about four times harder than calcite. A piece of quartz can scratch a sample of calcite but calcite cannot scratch quartz. If you have a sample if each try to scratch one sample with the other to observe the difference in the hardness.

You also can test the hardness of these two minerals using a pocketknife. The blade of the knife has a hardness value between calcite and quartz. The knife can scratch a calcite crystal but will not scratch quartz.

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate. The Mohs scale of mineral hardness based on scratch hardness comparison defines value 3 as calcite. Other polymorphs of calcium carbonate are the minerals aragonite and vaterite.

Aragonite will change to calcite over timescales of days or less at temperatures exceeding 300 C and vaterite is even less stable. Are quartz gold and calcite a mineral. Asked by Wiki User.

Look in places where gold and quartz occur naturally. Gold usually originates upstream from where it is panned or has been panned in the past. These regions include areas where volcanic hydrothermal activity has happened in the past near old gold mines.

Quartz veins are often formed in areas where the bedrock is fractured by tectonic and volcanic activity. A steel knife will not scratch quartz. Quartz crystals are usually clear but can occur in almost any color.

Shows a rhombohendral crystal shape. This can be described as a drunken or tilted 3-dimensional rectangle. Calcite fizzes readily with HCl.
