The type of clay mineral depends on the parent rock and on local drainage. Some minerals, such as quartz, are resistant to the chemical weathering and remain unchanged. quartz A resistant and enduring mineral found in many rocks ( granite, sandstone). It is the principal constituent of sands and silts, and the most abundant soil mineral.

DESIGN AND DEVELOPMENT OF A MINERAL EXPLORATION ONTOLOGY by HILAL SEVINDIK MENTES Under the Direction of Hassan A. Babaie ABSTRACT In this thesis, an ontology for the mineral exploration domain is designed and developed
For this purpose, mechanical strength, expressed by the maximum load at the point of failure, needs to be transformed into quantities that can be used within the design of crushing stages,, by linking the crusher reduction ratio or crushability index (CI) with compressive strength or impact strength index (ISI).
Friedrich Mohs, a German mineralogist, developed the scale in 1812. He selected ten minerals of distinctly different hardness that ranged from a very soft mineral (talc) to a very hard mineral (diamond). With the exception of diamond, the minerals are all relatively common and easy or inexpensive to obtain.

Its higher refractive index (n = ) makes ZEISS Single Vision Sph Glass thinner and lighter than ZEISS Single Vision Sph Glass in both the plus and minus ranges. Both benefits – increased wearing comfort and an improved appearance – have made ZEISS Single Vision Sph Glass the standard glass lens for low to medium prescriptions.

A uniform mass of expansive soil which becomes saturated with moisture will exert pressure in all directions as each individual expanding clay mineral seeks to occupy more space. The direction and magnitude of soil movement will depend upon the magnitude of the confining pressure at any particular point of resistance.
