Where can I find Scapolite?
Large crystals of common scapolite (wernerite) are found in the apatite deposits in the neighborhood of Bamble near Brevik in Norway, and have resulted from the alteration of the plagioclase of a gabbro.

What is the density of a topaz?
| The Properties of Topaz | |
|---|---|
| Chemical Symbol | Al2(F,OH)2SiO4 |
| Name | from Topazios, the Greek name for an island in the Red Sea, meaning to seek. The island was a source of peridot, often confused as topaz. Also reported to be of Sanskrit origin from ‘topas’ meaning fire. |
| Relative density | 3.5-3.6 g/cm3 |
| Hardness | 8 on Mohs Scale |
What products that contain apatite?
Fertilizer, phosphoric acid, hydrofluoric acid, gemstones, ore of rare earth elements, pigments, gemstone. Serves as a hardness of 5 on the Mohs Hardness Scale.
How is scapolite formed?
In metamorphosed igneous rocks, especially gabbro and basalt, scapolite often occurs as complete or partial replacements of the feldspar grains. Crystals of scapolite are sometimes found in pegmatites and rocks altered by contact metamorphism. Scapolite minerals are easily attacked by weathering.

What is the volume formula for an ellipsoid?
Here, we provide you with volume formulas for some common three-dimensional figures and also for the ellipsoid and the hollow cylinder that are not so common. Use π = 3.14. How to use the volume formulas to calculate the volume. The height is 8 inches and the radius is 2 inches.
What is the formula for the volume of a pyramid?
The formula for the pyramid’s volume is given by one-third of the product of the area of the base to its height. Such as: Its volume is measured in the following units: Note: Always make sure to keep all the measurement units same while calculating the volume.
How do you calculate volumes of different shapes?
Volumes of many shapes can be calculated by using well-defined formulas. In some cases, more complicated shapes can be broken down into simpler aggregate shapes, and the sum of their volumes is used to determine total volume.
How do you find the volume of a spherical cap?
The equation for calculating the volume of a spherical cap is derived from that of a spherical segment, where the second radius is 0. In reference to the spherical cap shown in the calculator: Given two values, the calculator provided computes the third value and the volume.
